Most affordable tubes I've found, bonus that they are also heavy duty. No issues on install, just inflate them slightly so they take form.
I use these tubes on all my bikes. Very tough. Heavyweight but I stopped pinching tubes on rocks in the mtns and square edge holes on the vintage mx.
Compared to the OEM tube it's twice as thick. Install wasn't much worse than regular tube. Great deal, I'll be buying more of these!
I’ve been using STI tubes for a while and have no complaints
Super heavy duty for the price
So far, also didn't pinch when i slapped it in
Bought for my starcrosses seem to be heavy duty!
Works great. No problems
