I run tires between 25 and 32mm, and these tubes are my go-to for all of them. My rims go up to 30mm depth, and I think that up to 4-5 more mm would still work fine. Not much to report, as I've had zero problems with these tubes and haven't gotten any flats lately.
I've been useing this tube for many years and have yet to find a negative side.They are easy to mount,hold pressure well,and not alot of flats.A great product.I dont use any other.
I use a racing bike as a commuter in the city. It makes it so keeping up with cars and riding on the streets is less rough. However, with all the bumps, potholes, glass, etc using full blown racing tires and tubes is a pretty bad idea. I try to find the balance of durability and speed. Right now I have Gatorskin tires, a PVC liner, and these tubes and things are going great. With this setup I've only had one puncture in the last 6 months (used to be one a week), and I can pump with High PSI to still have good performancedurability. The added rotational weight is present, but less than other tubes and the price is good.
Smooth. Pump them up and weeks later you are at 90%. They seem to help good tires resist punctures. Don't ask me how.
I have been using these tubes with the Michelin Mud2 tires for cyclocross racing. They are most resilient tubes I have used. A small puncture only resulted in a slow leak and I was able to finish the race. I have pinch-flatted on one occaision, but that comes with the territory.
These, in combination with Continental Gator Hardshell tires have eliminated my frequent flat problems. These tubes are noticeably thicker than any other tube I have used. So they are going to be slightly heavier. But man, do they give confidence that I'm not going to have a lot of flats. These are the only tube that I have ever used that will hold 90 psi pressure for extended periods of time. I'm a weekend rider, and before using these tubes, my tires would typically be down to about 40 psi after the 1 week interval. These tubes are usually still up in the 80 psi range after a week.
I've been using Michelin tubes for more than thirty years and find them to be reliable. I've never had one fail at the valve stem, where the cheaper tubes tend to fail.
I've been using these tubes for years and have had only one defective tube. This is a much better record than I've had with house-branded tubes such as Performance. These aren't the lightest tubes out there, but the rubber thickness appears uniform, the seams are well made, and the valves work great. Sorry that the previous reviewer had problems with these, but my friends and I have all had good results with these.
Ive used a lot of these tubes over the last few years. They hold air pretty well and dont give me any pinch flats. The only reason Ive had to replace them was cuts from glass on the road, and no tube is expected to withstand that kind of damage. Will definitely keep using these.
