03/29/2026 JPBT Day 7 : Swiss (Near) Miss
It’s always fun to meet other bike tourists, and yesterday we met Nicholas and Manuela, along with Manuela’s sister. Nicholas and Manuela had ridden across Asia by bike, starting in Albania, making it all the way to Thailand, and then flying to Kagoshima - the same starting point as us. They were using Komoot to plan their route, and with the dizzying number of possible roads out here, it felt almost impossible that we’d see them again; the road map is as convoluted as a Sumo wrestler’s varicose veins. Yet later today, at one of these tiny mountain intersections, they rolled across our path at a perfect 90-degree angle. It was uncanny enough that we invited ourselves along on their ride.
We are a little more seat-of-the-pants in our touring style, so joining forces with them was like signing up for a guided tour. We just followed them: first to a grocery store, then to monte-belle (an outdoors shop) where we finally were able to buy stove fuel. Just like that; all that fretting, solved in five minutes by following two competent Swiss. Now if we could just magically send the drone and maybe the computer safely home or to storage in Tokyo, we’d be set. Carrying too much stuff weighs on me mentally even more than physically; my brain is wannabe-Swiss efficiency, so I constantly begrudge burdensome baggage.
We then followed them to a campground they knew about (and we didn’t), only to discover it was closed. Being good, rule-following Swiss, they actually called a phone number on a sign to confirm. Janet and I probably would have employed our usual touring strategy, which is somewhere between optimism and trespassing, and operated under the “better to ask forgiveness than permission” model. Now that option was off the table, so we looked elsewhere. This is where we had our amicable breakup, making sure we would remain friends splitting custody of the route 50/50.
We are always intent on meeting mostly local people wherever we go, but there is also something really fun about meeting people with a shared language and more familiar culture. We really enjoyed spending the afternoon with these guys and hope t meet them tomorrow on the volcano.
Speaking of meeting people, most of our local conversations seem to be with motorcyclists. They seem attracted to is, maybe because of the brotherhood of two wheels.
One guy today was especially interesting. He did all of his own maintenance on his BMW, which he had owned for its entire 44 years. This bike seemed big for Japan. It was in spectacular condition and had only 43,000 kilometers on the odometer. I asked whether he belonged to a motorcycle club, and he said, “The motorcycle is the one thing I can do by myself. If I wanted to be with that many people, I would take the tour bus!” That alone made me like him.
His ride home from where we were talking would be two hours, and he seemed to think the USA was safer for two wheels than Japan. Janet and I postured the opposite opinion. I guess the grass is always greener, though in this case I still think we’re right… that the grass is actually greener here than in California (and probably quieter, steeper, and better paved too).
After that, we scurried off into the redwood forest and quickly found a perfect place to hide the tent and have a quiet night.

I thought we were seeing fog. Nope! It is an AQI of 166!! Red zone! I had a sore throat in the morning, and now I know why.
This gorge! It was amazing!
We did an extra ascent… for the view.. oops!
Well, the road was closed but we snuck by. No problems. Later we found out that all 3 of the other cyclists we met also went this way. One of them was ahead of us; we recognized her tire tread.
The tire blew off the rim! This is the second time this has happened to us. The other time was also after a long descent. Both times we did a very steep descent, and then at the bottom - after a couple of minutes - BOOM!💥. We are so lucky that this did not happen while going downhill. Last time, we were using an emergency “non tubelesss tire” - but this time we are using new, high quality tires designed specifically for this type of rim. UGH! Im starting to long for the simplicity of the old days when rims and tubes were more predictable.
Almost all of our riding is on one lane roads. I couldn’t be happier. I hope we can keep riding like this because every route has been my favorite type of riding.

This is the mountain next to the volcano we hope to ascend tomorrow.
Camp! I had a mini water heating fire going but then we saw people and Janet got it out fast.. while I put my clothes on!

AQI due yo the volcano? Or people? Loving the descriptions…

Leonard Zinn has been writing an interesting series on his substack about mainly roadbike tubeless tires blowing off rings catostrophically. Since I'm not a paying subscriber, I've only gotten to read about half of the articles via email. Long story short, I for sure wouldn't trust them at typical "roadie" pressures, maybe gravel is fine, but I suspect you're operating at that safety margins on a loaded touring bike. Glad it happened when you were not moving!
Brian L.
Janti of the Jantai - yea! We don’t measure pressure except by the “pinch test” but never had an issue with the continentals. I aim for 40 psi on the tandem with the 2.2 width, which is fine. Overall, though, I’m leaning towards going back to tubes except for the MTB. It’s tough because I’m so heavily invested in these rims on all the bikes. I bought the hookless cool-aid.
Janti of the J.
The only potential recommendation I can offer, is to add a few more wraps of rim tape. This will better force concentricity of the tire to the rim, and might prevent a looser tire bead from stretching over the rim. Also might make tire swaps more difficult, but also enhances sealing wo use of a compressor because the effective rim diameter is larger
Matt C.
I just don't understand why anybody would think hookless rims are a good thing...we've had rims w/ a bead groove since forever, and now with disc brakes the overheating carbon rim-walls are a thing of the past. Sure they can be a pain to seat the bead, but once you do and the bead is clean, then every tubeless wheel I've ever had locks the tire in like it's glued! And I like that I can go lower pressure when I want with no fear of the blow-off.
Gregg B.
I never liked the idea of hookless rims. Even with disk brakes the tire heats up when doing heavy braking, just no where near as much as rim brakes. That heat increases the tire pressure and with no hook off comes the tire. I’ll stick with fully hooked rims, and the difficulty that brings in getting it to seat.
Brian L.
Janti of the Jantai - almost all of my bikes have no rim tape! I bought rims with no holes and painstakingly threaded each nipple through the valve hole one at a time, maybe with a glass of wine at hand and Traditional Italian Music playing in the background. Each wheel was aboit à day to build, but guaranteed no sealant leaks inside! Gregg Bone - I think you are right about the heat. I plan to get some Bluetooth valve caps when I get home and then measure the pressure change after long descents. Matt Chapek - you’re right.. hookless seems silly. I “drank the Kool-aid” because the manufacturers said it was stronger (thicker) and for the tandem, I prioritized strength. We have never had an issue with Continentals blowing off, but these new RatTrapPass tires are “too close” to the blowoff threshold. We need some more leeway before the tire blows off. Now im riding squish… aboit 35 psi, even though it is rated to 55.
Janti of the J.
Sounds like you should definitely add rim tape
Brian L.
Janti of the Jantai - did Zinn say tape made it safer? On the “shelf”? Or where?
Janti of the J.
Rim tape makes the effective ID of your rim larger. Thus, for a looser tire bead, or one that stretches slightly at higher PSI, the tire can't shift as easily up or down (out of concentricity) and over the rim wall. You'd want rim tape that's ideally exactly the width of the rim bed (or maybe 1mm wider and then stretch it when applying). I'd guess 2-3 layerswhere it's harder to get a tire mounted, but the beads still snap into place, centering the tire at 50-60 psi.
Janti of the J.
Oops I meant OD above... Also, I would toss the tire that blew off the rim. It could just have a manufacturing defect, or be out of tolerance. And I'd guess that after blowing off a rim, it's ID is definitely out of tolerance as a result. Beads aren't supposed to stretch and tires have to be at a very specific diameter to be stay on a hookless room. That manufacturing tolerance is very narrow and probably difficult to achieve. Zinns main point is tire/rim interface safety margins need to be increased. Fwiw, I blew off an old race King recently while working to get the bead to snap into place. That tire had always been a loose fit, and I'd built up the rim bed accordingly to try to get it to seal up. At ~60psi, boom! In the trash it went

My favorite photos of yours are always the bike infrastructure (roads, paths and bridges) maybe because I can imagine how fun it would be to ride them.

Fantastic photos. I liked seeding the setup on Swiss couples' bikes. I know you like to travel light (perhaps even sans drone) but relative to just about anyrider else you two are usualkly the lightest. Sandals on all.
