Meanwhile, I’ve been thinking about commuting via Dionysus this week, but each morning when I get up it looks like rain. Yesterday I could hardly see a thing out the window.
It turns out only some of what I’m seeing is clouds. There’s a big helping of yellow sand from the Gobi Desert out there as well — the stuff we saw in pictures from Beijing last week.
About a month ago, Fearless Leader Joe and I were discussing rides we’d like to do and he mentioned he wanted to ride Shimanami Kaido. The Halfakid and I did this one back in 2018 on rental bikes. We did the route in one direction only that time, opting to take the ferry back from Imabari after the hard plastic rental bike saddles had done a number on our backsides. So we’ve been wanting to get our revenge since that time.
Within a few days, we’d agreed on the dates. I booked the shinkansen for the Halfakid and myself (Joe and Sanborn would be driving), and Nana found a nice onsen hotel within reasonable riding distance of the end of the route in Imabari. (There are apparently no onsen in Imabari proper — at least none we’ve been able to track down.)
As we prepared for the ride and counted the days, I started checking the weather forecast for Onomichi. With 10 days to go, it was showing a more than 70% chance of rain both days. I checked every day thereafter and we crossed our collective fingers as the forecast slowly improved.
I had another bit of excitement in the interim: Nana and I woke up one morning with fevers and coughs. We were eventually diagnosed with pneumonia. With antibiotics and a lot of rest, I quickly recovered. But I wasn’t really confident I’d be able to make the trip until about 10 days before the start.
Packed and ready
I had a spare travel bag for the Halfakid, a real rough-and-ready rinko-style bag, while Kuroko got her usual pampered treatment in the padded bag. It was my first time taking this bag on the shinkansen. I’d reserved the seats with luggage space, and the bag stuck out a bit into the aisle. No one complained about it, though. (When the Halfakid boarded at Shin Yokohama, he stuffed his bike in behind and partly atop this — I didn’t get a photo.) After three-and-a-half hours on the bullet train, we switched to a local and arrived in Onomichi on schedule, four hours after I’d departed from Tokyo Station.
The latex scare
We’d had a message from Fearless Leader Joe that he and Sanborn (blues name: Sambone) had arrived an hour ahead of schedule, but there was no sign of them at the station. The Halfakid and I set about unpacking and assembling our bikes, and then changing into our riding gear. I’d deflated my tires to help them fit in the travel bag, and the front in particular had leaked some sealant along the rim. I was a bit concerned it might not seal again when I pumped it up, but there was no trouble. The errant duo arrived just as we’d finished, and FLJ gathered up our bike bags to stow in his car. He returned, pushing his beautiful Chapman bike — he’d had to remove the handlebar to fit it in the back of his car, and he wanted my help to get it back on the bike. That took just a minute or two, and then I fitted a new pannier to the rear rack for him as well. (What happened to the bags I put on the bike in England, Joe?)
The outlook quickly improved
We started a bit after 11, which was later than we’d hoped. But we were in luck with the weather. It had been raining in the morning, but the sun was beginning to shine as we took the ferry from Onomichi Port to Mukaishima. I started the Garmin and we set out on the first few, flat kilometers. As soon as we got to the first climb, though, an easy 3% grade up to the 1,270m Innoshima Bridge, the others raced past me as I slowed to a crawl. I’d let them know that there was a good spot for photos at the entrance to the bridge, and that’s where I found them waiting when I eventually got to the top.
Skinny guys get there first
That set the pattern for the rest of the day. As the weather continued to improve, allowing us to enjoy the views across the Seto Inland Sea, the lads would follow me on the flats and let me set the pace. But when it came to the climbing, they would rocket ahead as I shifted progressively downward and took my sweet time. The lead-up to each bridge is a gradual and winding 3%, but the climb up to Miyakubo Pass on Oshima is a long stretch at 5-6%. Four years ago, the Halfakid took a long breather halfway up this climb, but this time he was far ahead of me as I soldiered onwards and upwards.
More blossoms
As the day wore on my energy decreased and each new climb seemed longer and harder. I was very pleased when I recognized the spiral ramp leading up to the Kurushima Kaikyo Bridge, the last of the day. The others stopped at the top of the ramp to chat but I continued immediately across the 4km-long bridge, doing my best to enjoy the view as I anticipated the spiral descent down the opposite side.
Imabari Castle
At the foot of the off-ramp we departed from the Shimanami Kaido route and continued along the sea into Imabari. I’d selected this route to avoid traffic going into the city, and it was a success. In the end we only had a couple of kilometers of city traffic to negotiate before arriving at Imabari Castle shortly before 5 p.m.
We took a brief rest at the castle, finished our snacks and called the hotel to let them know to expect us about 6 p.m. On the plot of the route from the castle to the hotel it showed a steady climb, just 1-2% along most of the distance, but with an upward flip to 5-6% at the end. In my tired state I wondered if I’d really be able to make it in an hour. As the shadows were lengthening, I put on my bright yellow windbreaker and turned on my taillights before setting out.
The climb turned out to be so gradual for the most part that it was hardly noticeable. When we’d gone a few kilometers out of the city, we saw road markings for a cycle route to our goal: Nibukawa Onsen. We soon came to a decision point when the road markings said to continue straight ahead while the route I’d set in the Garmin was telling us to turn. We voted to go with the Garmin and it turned out to be a good choice. My route took us through some lovely rural farm country, and I could hear Joe and Sanborn discussing what a great, scenic ride it was.
I stopped for a final breather on a bridge over a small waterfall on the Nibukawa, just where our route joined up with the road markings again. The Garmin showed 1.5km remaining, so I put all I had into it and powered my way up the final steep portion. We soon rolled through a gateway and found the hotel just a few dozen meters on, surrounded by cherry blossoms.
View from the hotel parking lot
The hotel staffer greeted us and opened up a spacious garage with bike racks inside. This was a welcome development! We checked into our room and headed immediately for the baths, knowing our bicycles were securely out of the elements.
Place setting for dinner
The baths — indoors and out — were relaxing and refreshing after the day’s ride, but they weren’t quite warm enough to fully satisfy us. Dinner on the other hand was sumptuous, with a variety of delicious dishes. There was so much food, in fact, that I wasn’t able to finish it all (something that rarely happens, particularly after a 90km ride).
Did not die
Day 2
We got a much better start for our return, departing at 8:21 after a delicious but not quite filling breakfast. I’d set a somewhat different route at the start, staying away from Imabari Castle and shaving off a couple of kilometers. But there were a couple of steeper climbs before getting to the Kurushima Kaikyo Bridge, and for the first time on this adventure I stopped for a rest midway up one of the longer rises. The day was warming up quickly, with blue skies and fluffy white clouds, by the time we reached the bridge’s spiral entrance ramp. I made it up to the top without having to stop for a rest, and soon we were speeding our way across the 4km span.
Park bench showing the waypoints of the Shimanami Kaido
We stopped at a convenient park on the opposite end of the bridge. We wanted to buy water from the vending machine, and I wanted to confirm a mechanical that had been brewing from the previous day: my rear derailleur wouldn’t shift up past about the middle of the sprockets. I pulled back the shift lever hood to expose the cable, and the Halfakid confirmed my suspicions with his eagle eyes: the shift cable was fraying.
This was the same issue that hit me in the middle of Lejog, and ended with me putting the chain into the spokes, breaking several. I knew from that experience not to try to mess with the derailleur adjusting screws. Because I still had full use of the lower half of the sprockets — the ones I need for climbing — I just shrugged and hoped the cable wouldn’t break completely before the end of the ride. Without the use of the higher gears, it just meant I’d coast more on downhills instead of pedaling to increase my speed.
View of the Seto Inland Sea Four cyclists, one bike
With our early start, we covered much more distance before lunch than we had the previous day. In fact, we ended up in the same location at lunchtime, with just 30km left to ride. We looked about for a different restaurant and chanced upon a very nice place serving anago. We dallied an hour over lunch before heading out into the bright sunshine once again.
Tatara Bridge
In the afternoon we had just 30km left to go, and Miyakubo Pass was behind us. There were just a couple of brief climbs remaining. The entrance to Innoshima Bridge is marked by an enormous dinosaur statue and a steeply rising road. I paused to catch my breath and drink some water before continuing up the more forgiving cycle path.
Very near the end
The others were waiting for me by the cherry blossoms on the opposite end of the bridge — which had been our first stop the previous day. They continued to chat cheerfully as I drank more water and took a snap of the blossoms.
The tree at the end of the bridge
We descended from the bridge onto Mukaishima, our last island of the day, with less than 10km to go. Sadly, the wind — which had been with us most of the day — suddenly was in our faces. I pressed on the best I could manage, and the others followed close behind. (Sanborn later told me he’d been drafting so close behind that he hadn’t even noticed the headwind. I should have made him lead at this point.) Traffic picked up as we neared the ferry port, and the signs along the edge of the road counted down the kilometers for us. We finally made the last turn towards the port and rolled up to a stop, exhausted (at least I was) and triumphant.
Back at Onomichi station, preparing to pack up
We cooled our heels waiting for the ferry, and then crossed to the station. We arrived just before 3:30, which left us plenty of time to pack up the bikes, change our clothes and sit down for a coffee and some baked goods before our train departure at 5:14. And although Fearless Leader Joe and Sanborn had a long drive ahead, they remained with us until we boarded the train.
Until next time!
The ride home was uneventful except for the fact there was no food or drink service on the shinkansen, as a coronavirus prevention measure. We’d bought snacks at Fukuyama to eat on the way, but I’d been expecting to get a cold beer once the train was in motion.
Continuation of failure to expire
Links
Before I get to the gory details of fixing the shifter cable, here are a couple of resources for Shimanami Kaido that I referred to while writing this post:
We had no flats, and my tires continued to hold air despite having leaked some sealant when I deflated them for the travel. Which brings us to the shifter cable. Saturday morning I unpacked Kuroko, putting the frame in the bike stand, and I checked my stock of cables: three brake cables and one shifter cable.
That’s it on the left
After making sure I had what I needed, I cut the end off the cable and pushed it back through the housing towards the shifter.
The first cut is the deepest The damage is done
With the shifter hood pulled back and the cable pulled free, the damage was apparent. I was a bit worried I’d have trouble freeing the mushroom head from the shifter, as I did the last time when the cable had snapped, but there was no problem. As I had plans to see the cherry blossoms in the afternoon with Nana and her mother, I left the bike in the stand at this point and cleaned up.
This is the way we clean the chain
On Sunday, rather than jump right in at replacing the cable, I decided to clean the chain and rear sprockets first. They were certainly due for a good scrubbing.
Not perfect, but a huge improvement Mushroom in its slot
I threaded the new cable through the shift lever and the cable housings with very little trouble. I wanted to make sure that the mushroom head was fully captured by the rotating slot in the shift lever, because that had been troublesome the last time I replaced the cable. Holding the free end of the cable in tension with my left hand, I worked the shift lever back and forth a few times while watching through the tiny opening in the side of the lever. Finally I was satisfied that the mushroom was fully engaged, and I continued threading the other end of the cable through the remaining slots and housing.
At this point I noticed how dirty the rear derailleur was, so I spent a few minutes cleaning up the jockey wheels. While I was at it, I had a go at cleaning the chainrings as well.
That’s dirty!
Finally, I cinched the pinch bolt tight against the cable. I ran through all the gears a few times as I adjusted the tension via the barrel adjuster. It just took a couple of twists before I was happy with the performance. I tightened the pinch bolt a bit more and cut the cable to length. I wasn’t able to find a cable end immediately — I ended up stealing one from one of the brake cable packages.
Ready for adjustment The finishing touch
After a last run through the gears, I reached for the front wheel to put it back in the fork, only to find it was flat. I’d pumped it up Saturday morning when I unpacked the bike and propped it up against the wall of the Workshop in the Sky, and here it was flat again just a day later. I pumped it up again and this time I could clearly hear the air hissing from the bead, not far from the valve. I swirled the tire around, hoping to get some sealant into the leaking area, but nothing changed.
I finally realized there might not be any more sealant left after all the leaking. With a sigh I let the remaining air out of the tire and removed the valve core. Using the syringe, I poured in a generous helping of sealant. I charged the tire pump reservoir up to 120psi, attached the pump head to the valve and let it fly. The gauge quickly dropped as the air rushed into the tire, but then it slowed and finally held at 40psi.
I listened once again and didn’t hear any leaking. I took the pump head off the valve (letting all the remaining air escape) and screwed in the valve core. Then I pumped up the tire to 60psi a final time. After closing the valve I swirled the tire some more while listening for leaks. Nothing. Satisfied, I put the wheel back in the fork and let Kuroko down off the stand.
Very little remained to do. I put the pedals back on after applying some fresh grease to the threads and remembering which way to turn them. I loosened the seat post clamp and retightened it to the correct torque. Finally I replaced everything I’d removed, either for packing or for the repair: the tire pump, the saddlebag, the lights.
Done and done
Prognosis
I’m two for two now on fraying the rear shifter cable after traveling with Kuroko in a bag. While the Evoc Bike Travel Bag Pro that I used for Lejog is different from the Ostrich OS-500 I used this time, and the placement of handlebar and fork in particular is very different, both involve turning and twisting that is potentially putting some stress on the shifter cable. On the other hand, I’ve used the Ostrich before — for the 2018 Tour de Tohoku and the Kyoto-Nara-Osaka ride the same year without any trouble. Searching for “broken shifter cable” brought up a number of hits, including this blog, but no particular mention of travel bags.
I’ve learned that Shimano shifters in particular are prone to fraying and breakage, with some riders reporting getting as few as 1,000km out of a single cable. Inspecting the cables for incipient wear can be tricky given the tiny access port available — even the Halfakid with his young eyes had difficulty making sure of the fraying when we stopped en route. So to avoid this sort of mechanical again (or to mitigate for it), I’m left with a few options:
Replace the cable periodically, even if there’s no sign of wear. (Signs include resistance to shifting or frequent need to reindex the gears.)
Carry a spare cable and the tools needed to replace the cable in the field.
Embrace the uncertainty as just one more quirk of the cycling life, like ridiculous padded lycra shorts.
Convert to electronic shifting — something I’ve been considering for other reasons, but it’s quite expensive.
Switch to a single-speed bike.
Replace my Shimano groupset with SRAM (which by all accounts is not subject to this same issue) — also rather expensive and not something I’m inclined to do. (Dionysus is on a SRAM 1x set-up, and I’m completely happy with that.)
Go to another gearing system, like the Rohloff Speedhub on Fearless Leader Joe’s Chapman bike. Not only is the Speedhub expensive and heavy, but I’d need a whole new bike.
Sell off the bike and take up darts.
I’m going to ponder these options for a while before coming up with a plan of action.
I’m spending my day off work on important tasks like getting a clean bill of heath from the doctor and packing up Kuroko in the carry bag for an upcoming trip.
Four tires, one wheel drive
Kuroko of course is right where I’d left her after sorting out the slow leak in the rear tire. Before disturbing her rest, though, I reviewed my notes from a previous use of this bag: Yes, I needed to remove the pedals. No, I didn’t have to remove the handlebars, and it was better if I didn’t, but it makes things very tight.
This should be easy, right?
After getting the bag from the closet, I had a go at the pedals. It’s easier when both wheels are on the bike, but I thought I might be able to get the job done with Kuroko in the stand as she was. I was fine, once I remembered which hand was my right hand (for the drive-side pedal), and that the non-drive-side pedal is left-hand threaded.
Bigger wrench helps
I have a pulley I took off a dummy hub I almost never use, and it’s the perfect thing to keep some tension on the chain and derailleur when I’ve got the rear wheel off the bike for transport.
It’s not just the balcony that needs cleaning
And just like that, the pedals were off and the dummy hub on. The next step was to lower the saddle, which was tricky as the bike was held in the stand by the seat post. With the saddle down, it was just a matter of persuading the bike into the bag.
Can I zip it up?
Based on my previous experience with the bag, I let most of the air out of the tires. I’m a little concerned this will allow the beads to unseat and I won’t be able to reinflate them when we arrive at our destination. In the worst case, I’ve got spare inner tubes I can put in to get the bike rolling.
Even with the tires deflated and the seat pushed all the way down — and despite the fact it’s a small frame — it’s still a tight fit in the bag. It took some pulling to get the zipper done up. But it’s all done now and I can concentrate on packing the rest of the things I’m going to carry for trip.
And you can stay there and think about what you’ve done
Hot on the heels of Thursday’s success in tracking down and fixing a slow leak, I returned to the balcony this cloudy but mild Saturday morning to see if I could mount the final tire — the spare front wheel that I’d had no luck with a couple of weeks ago.
New toy
I’ve been out on the balcony a few times since Thursday to give the newly fixed tire a squeeze and a few bounces. This morning I decided to give my new toy a try. The pressure showed nearly 52psi, satisfyingly close to the 60psi I’d inflated the tire to when I was finished on Thursday.
Sanity check
Just as a sanity check, I attached the tire pump. The reading was in fair agreement, particularly considering that attaching the tire pump usually results in a small loss of air.
That done, I put that wheel to one side and pulled out the spare front wheel, the one with the dynamo hub. This has been sitting with the tire on but not sealed since I first tried to mount it two weeks ago. It’s also the one I scavenged the valve from for Thursday’s fix, so the first order of business was to insert a new valve.
New valve in, core removed
With the valve in and the core removed, I pumped up the air reservoir, soaped up the tire and rim, and attached the pump head. The first go just resulted in a lot of air whooshing out of the pump and through the valve, and there wasn’t even enough bubbling anywhere to give me something to investigate. So I just charged up the pump once again and soaped up the tire, and let it rip. This time there was progress. The tire didn’t pop onto the rim, but it held the air for a few seconds, expanding all around the circumference. Large soap bubbles appeared all around the rim, showing that we were close to a seal.
Third time’s a charm — nearly
Charming lack of bubbles
On the third try (pump up reservoir, lather up tire all around the rim), there was a satisfying Pop! Success! I quickly worked to add sealant to the tire.
Latex infusion
At that point I thought I was good, and so inserted the valve core and pumped up the tire — or tried to.
High and tight
I could quickly see I wasn’t getting anywhere. So once again I removed the core, charged up the reservoir and gave it the business. This time I was rewarded with a couple of very sharp Pops!
Elated, I once again inserted the valve core and pumped up the tire. It was holding air this time. By the time I got up to about 40psi, I could hear some leaking. So I removed the pump head and picked the tire up to swirl the sealant around inside. After a few seconds of swirling, the hissing of leaking air stopped, and I resumed pumping up the tire to 60psi (or thereabouts).
As always, I finished up the job with more swirling of the sealant, a few bounces of the tire on the balcony floor, and a close inspection of the bead all the way around to make sure it’s evenly seated. Done!
Four for four
I’m now four for four on tubeless tires seated to Kuroko’s wheels — the main set and the spares. I have plans for the spares, which have a somewhat more aggressive tread pattern than the slicks on the main wheels, but they’re not quite ripe. In the meantime, I picked up the spare rear, the one I’d seated the tire on two weeks ago. It was noticeably soft, and yet was holding air. I decided to top it up again and call it a day.
A wee bit low Four tires, one wheel drive
(I have more time today. I could probably clean up some of those old tires … )
Overall Kuroko’s new Panaracer tires have been a huge improvement over the René Herse skins with their weeping sidewalls. But a few days after I first got the GravelKings on, I noticed the rear had a slow leak. It would be fine for the course of a ride, but over a couple of days it would lose most of its pressure. If I left the bike sitting for a week, it would be totally flat.
I’ve let it go for a few weeks because I was fine with topping the tire up before each ride, but I knew that I wanted to sort it out sometime. As this afternoon was warm and wind-free, and I had some free time on my hands, I knew this was the perfect chance for some maintenance.
Not quite what I envisaged
The time-tested method for finding a slow leak is to inflate the tire and immerse it in water. I pumped the tire up to its limit, filled the bucket to the brim with water, and … the result was laughably unlike what I had envisaged. I suppose I could use the bathtub, but I could imagine Nana’s reaction when I carried the wheel into the bathroom, even after I promised to clean the tub when I was done. Instead, I filled the bucket with soap suds and used a brush to lather the suds all around the tire where it meets the rim.
J’Accuse…!
I inspected the rim carefully all around the bead on both sides of the tire. I didn’t find what I was looking for, and so I lathered up the tire again and had another look. Around and around and … nothing! I set the tire on the floor and pondered my next step. The bathtub suggestion kept peeking its head out from the corners of my thoughts. And then I saw it! Bubbles forming around the valve core!
I took off the valve cap, lathered up the valve again and watched: no mistake, the valve was the source of the leak.
With the source of the leak identified, I quickly loosened the valve core to inspect it. (Note to self: Let the air out of the tire first next time.) There was a bit of grime and latex sealant stuck to it, so I spent some time cleaning it up until it was spotless. I also tried to clean out the valve stem with some twisted paper towel. Then I reinserted the core in the valve and filled the tire.
Once again, the soap bubbles betrayed the leaky valve. I used the tool to make sure the valve core was in as tight as it would go, but it made no difference. The bubbling continued to grow as the air continued to leak.
OK, I have a spare
In order to replace the valve, I needed to remove the tire — at least partly. I worked the tire levers with care to avoid spilling the latex sealant inside the tire. I was mostly successful. Of course a little seeped out onto the rim, but it cleaned up quickly with some paper towel. And I only needed to remove one side to get the valve out.
Not a huge amount left
There was not quite as much sealant left inside the tire as I imagined. This allowed me to work without creating a huge mess, but I think I should probably add some more before I get a puncture.
I’m sure if I were to search through the parts bin I could come up with several spare valves, but the first thing that came to mind was the one I’ve got on the spare front wheel, which has been sitting unused on the balcony since my return from England nearly two years ago now. I’d put a new valve in a couple of weeks ago in preparation for mounting a new tire, but as I haven’t seated the new tire yet, it was a moment’s work to get the valve out and insert it into this rim.
The new core (top) and the bad old valve (center left)
With the new valve in place, it was the work of a minute to get the tire back on the rim, wipe up the leaking latex, and prepare for inflation.
Satisfied!
I charged up the air reservoir, connected the pump head and turned the tap. Immediately the tire gave a satisfying Pop! Two more, louder Pops! followed in quick succession as the tire seated itself on the rim. I hastily removed the pump, screwed in the valve core, and then inflated the tire once again. In about a minute I was lathering up the new valve and looking for leaks.
OK now it’s leaking in a new spot
Immediately I noticed some bubbling around the valve, but this time from a new location. With the old valve, the bubbles had been forming around the valve core at the end of the stem. This time the bubbles were coming from the base, where the valve emerged from the rim.
Satisfied!
I picked up the wheel and swirled it around, allowing the sealant to coat the interior in every possible location. After a few seconds of swirling, I set the wheel down and once again lathered up the valve. This time no new bubbles formed. I waited a minute or two, reapplied the soapy water and watched: no new bubbles!
I’m not going anywhere the next couple of days. I’m going to check the tire again tomorrow. If it’s low again I’ll remove the valve core and add some sealant (which I forgot to do in my haste after the tire inflated with the new valve) and try once again. Regardless, I’m confident Kuroko will be better off now that I’ve disposed of that rotten old valve core.
I don’t have a lot to say about today’s ride. I’ve been thinking about a new route that includes both Tamagawa and Arakawa. But the short version of that ride clocks in at 125km, and as Nana pointed out this morning, I should have got going before 9 a.m. if I’d planned to make that kind of distance.
So I set out with just “Tamagawa” as a destination, and along the way remembered I hadn’t seen the kawazuzakura yet this year. These are an early blooming variety of sakura, with dense, intensely pink clusters of petals. So I decided that was the first order of business.
I was making good time until I hit the river, and there I was heading into the wind. I just kept shifting down to keep my cadence up, rather than trying to power my way into the wind. I realized at this point I didn’t have my legs today, and similes involving the strength of kittens came to mind.
Pink as you wanna be!
The kawazuzakura were in full bloom — in fact a bit past it, as the green leaves were vying with the pink blossoms. Some joggers and cyclists were stopping for photos, like me, but others were simply passing by. I should have come last week, when the skies were blue.
Masks for peace
I continued fighting the wind all the way down the river to Haneda Peace Shrine. I’d set the GPS on navigation mode, so I wouldn’t be constantly checking it for stats, but I did sneak a peek now and again. I’d been making 16-18km/h into the wind, whereas I typically make 25-30km/h on this stretch. After grabbing the photo at the shrine, I had a lunch of Nana’s world-famous onigiri and then messaged her I was on my way home.
There’s not a lot to report about the ride home. The wind was more or less with me at this point and I was making much better time. At Futako I had a brief rest and ate the last onigiri. After consulting the time, I messaged Nana that I would be home by 2 p.m.
When I ride to and from Tamagawa or my office, I pass by Blue Lug, a bike shop specializing in custom and made-to-order bike builds. I was ahead of the schedule I’d given Nana at this point, so I decided to finally stop in and have a look. I was not disappointed: If they don’t have it (or can’t order it for you), it’s likely you don’t need it. I’ll make an effort in future to buy things through them rather than Amazon. And maybe I’ll stop in the café
Despite my brief stop for window-shopping, I still arrived home well before the time I’d given Nana. I messaged her that I was home and then walked Kuroko to her berth in the basement. Bath and beer awaited.
The day dawned cloudy and wet, but by noon it was warm with hints of sunshine. I decided to have a go at mounting the tire on my newly rebuilt wheel.
Always the last place you look
I found the bottle of tire sealant right away, just where I expected to find it in the tool box. But it was nearly empty. I knew I’d bought another bottle, and so I started looking for it. I looked, and I looked, and … I took everything out of the toolbox, and didn’t find any sign of it. Then I remembered that I kept a number of bicycle things in a box in my den, as well as in an empty suitcase. The sealant was not in the box, and it was not in the suitcase.
I returned to the toolbox, and emptied it all out again. Nothing. It was a real head-scratcher. I was putting everything back in the toolbox, rearranging a few things as I went, and I was about to stick a small box back into a stack of boxes when I realized I didn’t know what was in the box. Wouldn’t you know it … I’d been looking for a black plastic bottle all along, and I hadn’t removed it from the box.
Charged up for the first attempt
With all the necessary bits in order, I filled a pan with soapy water which I brushed all around the tire bead. I charged up the air reservoir to 120psi, attached the head to the valve and let it go. A lot of hissing, a lot of soap bubbles, but not much luck. The bead was near to seating but it was leaking all the way around.
Valve core out
While I was resting up from the attempt, I looked around at the items I’d prepared, and I realized I hadn’t removed the valve core before trying. That was a moment’s work, and then I pumped up the reservoir again and soaped up the tire bead once more. This time when I opened the valve there was a lot of bubbling and then … it held. I hadn’t heard a loud pop when the beads seated, but the tire was holding some air.
Bubble, bubble, toil and trouble
I worked quickly then, superstitious that if I didn’t finish the job quickly, the seal wouldn’t hold. I removed the pump head and added sealant in through the valve. Then I replaced the valve core and inflated the tire again. This time I was rewarded with a couple of loud pops … the beads were fully seated.
Sealant in, air in
Done! I swirled the sealant around the newly inflated tire to allow it to reach all areas of the bead. Nothing left to do but check that the beads were seated evenly.
Here’s where the crying part comes in
As part of seating a newly installed tire, I like to bounce it sharply against the ground a few times as I rotate it. While I was doing this I thought I heard something loose. I picked up the wheel and shook it. Something rattled. Not the sound of the latex sealant sloshing around, but a definite rattle.
The realization dawned on me with horror. When I removed the most recent broken spoke, I’d dropped the spoke nipple inside the rim. I had spent some time trying to rattle it out and then gave up, figuring I’d take care of it when I was ready to rebuild the wheel. Then, a couple of months later when all the parts were ready and I had time to set out on the rebuild, I’d shaken the rim to get the nipple out, and there was nothing. I remember at the time I’d shaken the rim more than a little bit and given it a few slaps, but there was no rattle. I’d shrugged my shoulders, figuring the nipple had fallen out by luck when I’d stuck the rim out on the balcony.
There was not a peep from the lost nipple the entire time I rebuilt and trued the wheel. But now it’s back. And it definitely needs to come out. With luck I’ll be able to get it out via the valve hole and not have to remove all the rim tape. But it’s going to be a mess with all that latex to deal with.
If I have any luck, the tire will go on more easily the second time around.
Onwards!
Rather than deal with the loose nipple right away, I decided to put the wheel aside again and have a go at mounting the other tire on the spare front wheel. I’d already prepped the rim with fresh tape and a valve, and I spent a couple of minutes wrestling the new tire into place.
Soaped and ready
I gave the new tire the ol’ college try. Each time it seemed like it was about to get seated, but I was just blowing bubbles.
Blowing bubbles
The tire is still a bit mishappen from having been folded up in the packaging, so it might be easier to let it sit for a week and then give it another try. These are spare wheels, after all, so there’s no real rush to get the job done.
Papa’s got a brand new bag
My last bit of maintenance for the day was to replace the cockpit bag on Kuroko. There’s nothing really wrong with the current bag except it doesn’t leave enough room in front of the saddle when I dismount. Nothing dangerous, just makes things a bit tight. The new bag is a few centimeters shorter, which should make a world of difference.
Fat Wally’s gotta go Sukoshi more room in the crutch
I took everything out of the old bag — tissues, alcohol wipes, tire patches, minitool and omamori — and put it all in the new bag. With all that, my phone just fit. I’m not sure if my wallet will fit in as well. I’ve got a ride planned tomorrow and we’ll see if the change is worthwhile.
Today’s project is not related to cycling. I needed a box to send a small gift overseas, so I decided to fabricate one myself from an empty beer carton.
Initial plan vs beer carton Folds and perforations
I had a pretty good idea how I wanted to go about it, but I searched for some plans as a reference. After measuring the gift I made a rough sketch.
Unfortunately for my plans, the beer carton has a number of unexpected folds and half-perforated lines, to make it easy to use as a dispenser and to fold up for recycling. I realized I’d be better off making the box lid as a separate piece, and then I tried to line up the plans along the existing folds and perforations as much as possible.
Among my challenges were a complete lack of any kind of straightedge or cutting surface. (I guess these aren’t required in bicycle maintenance.) I used the edge of one of the cut-offs of the carton to draw lines, and I used the edge of my desk to make the folds. I scribed shallow grooves along some of the folds, but these ended up going nearly through the material when the fold was made, so I had to tape them up carefully to hold the whole thing together.
Making do with the tools at hand
After taping up the box bottom, I made a trial fit. I was pleased with the results.
Taping and fitting
No one was more surprised than I when the box lid fit on the first go!
Robert Gair spinning in his grave
In the end I was very satisfied with my handiwork, even though (as stated at the outset) it’s unlikely to win any design awards. The fit was good enough there was no need of any packing inside.
Not winning any design awards
Now let’s see if it survives the international post!
Project No. 2
March is filter changing month
The other thing on my to-do list this weekend was to replace the water filter for the kitchen sink. We were very pleased to learn our new flat came with a built-in filter that only needs to be replaced once a year. We no longer have to fool around with Brita replacements and remembering to top up the pitcher and waiting for the filtration.
We pick up the order form from the lobby desk and fax it in (yes! This is Japan!), and a few days later the box arrives. And then it’s just a matter of moving the things out of the way under the kitchen sink to make the swap.
The Fedex man brought my latest goodies today, a cockpit bag and a musette. I already have a cockpit bag, but this one is smaller to leave more room for my … more room when I dismount.
My phone juuuust fits in the bag. The true challenge will be when I put in the multitool, tissues, omamori, keys … It’s going to be a squeeze, but I expect it will be worth the effort.
Very lightweight musette
I’ve also already got a musette, a canvas one that came as an entry prize for the Bike Tokyo event. I use it to carry my water bottles and Nana’s world-famous onigiri from our flat down to the bike garage (where I stow the bottles on the bike and the onigiri in the saddle bag).
This one, in addition to being lightweight and having a slightly larger capacity, closes with magic tape. It also has a stabilizer strap so it won’t slip around in front and tangle with my legs if I ride with it. As you can see above, it packs into a tiny case that can be strapped onto the bike frame.
The burning question
I know after seeing these photos, everyone is going to have the same question: does the musette fit back in that tiny case? Well … almost.
This is on the second try
The forecast is currently for rain on the weekend, so it may be a couple of weeks before these bags get their trial by fire.
