rubber peels off from cotton
- Jakub, 7 December, 2016
A great tub overall. Feels great on grass, packed dirt, and dry harder surfaces (not tarmac or cobbles, but rather gravel roads). Gives a lot of confidence in corners in dry conditions. Out of three tubs I had, two separated between cotton and rubber (with the thread). Both times after ~350k off road. It started flapping as I was riding. I only wash my bike with water, no detergents. One surprising aspect was that they felt very slippery (more than I expected) on wet tarmac or stones & cobbles. Maybe only in comparison to their performance off road :).
