AFAIK, it isn't up to dealng with the rpm of a bicycle wheel and IME its use isn't that widespread. I wouldn't worry about rpm if that related to rotating mass concerns or imbalances, that wouldn't bother me. My MTB already rides with a pronounced "whop-whop-whop" effect due to all that stuff inside the tires. Getting a solid 100-110psi performance with foam is the challenge AFAIK unless it is a material that hardens inside. Anything much lower would seriously slow down a rod bike ride. -- Regards, Joerg http://www.analogconsultants.com/ |

A standard pack of 1/4" chrome steel balls in grade 25 is 4000 pieces in one matched sealed lot. That's what bearing makers sell in the same way that tire fill makers sell drum of this or drum of that. I've known riders who went with foam fill and had it installed at a Bobcat dealer for a moderate price. Not to my taste, but it's just not all that difficult or unusual a thing. -- Andrew Muzi www.yellowjersey.org/ Open every day since 1 April, 1971 |

It lost pressure suddenly and overnight without being ridden the day before. It started to split along a factory seam. This seems to happen ever since they started making them less than the usual 3mm thick towards the rim. Does anyone know who still makes the real stuff, 3mm thick all around? Or maybe another good version thorn-resistant tube? I am running 700c 25mm tires with an additional tire liner in there. Might go to 28mm in back some day. The only time I ever lost 3mm all-around tubes was upon violent tire blow-outs (sidewall failure). -- Regards, Joerg http://www.analogconsultants.com/ Joerg, you sure must be one hell of a rider in terrible conditions. Not really. I use my bicycles not much differently than my car. "Pavement ends" is not a reason for me to give up and turn around. On the contrary: https://cdn.shopify.com/s/files/1/23...g?v=1587241131 Today I had a large cut in my tubeless tire and that was the last straw. It is just too messy to use and fix out on the roads. Back to tubes and clinchers. I think that's a wise decision. It you'd add a tire liner that's even better. Two of us three riders yesterday have liners, one doesn't. Guess who got a goat's head flat ... -- Regards, Joerg http://www.analogconsultants.com/ I talked to a friend that does a lot of your type of riding and he said that you can buy tubes that have removable presta valves in them and you can shoot Orange or Stan's Racing sealant into them and pretty much end flat tires. The sealant in a tube I’ve used a few times over the years, I’ve always given up since they only seal very small holes, I’ve always found they puncture quite easily, make a right mess and not seal! Yup. I used the slime stuff years ago. One fine day I had slow leaks and barely got home. Next morning I found a mess in the garage under the MTB. Same with other riders. No more of that stuff. Tubeless you can seal with those kits roadside apparently, with both valves will clog if one doesn’t clean or take care. I found that switching to mildly less racy tyres on the gravel bike solved stopped the bike being a puncture magnet, and feels just as fast/lively etc. For me it's "thicker is better". To hell with weight-weenie concerns. Tire surface, tire liner, 3-4mm wall thickness in the tube. That requires a hell of a goat's head to punch through. On the MTB there is another tube around the tire liner, gives extra protection and prevents chafing. Of course, my dream would be some stuff I could fill the tire with, no more air. However, that would envirnmentally not be too good. They are available. See: https://air-fom.com/ Seen it but this does not instill confidence with me: https://air-fom.com/wp-content/uploa...comparison.jpg ???? The photo is showing that with a load of 12.5 kg the tire diameter is 50 cm whether air inflated or air foam. (which is printed in thelower portion of the photo) -- cheers, John B. |
