Tonight I tore the sidewall on my second NBX lite. Was just going around a turn and poof, big hole in the tire. I have some new ones but am a little hesitant to put them on. However, I have some Python air lites and the sidewall on these seems to be much thinner than the NBx lite but I've had no problems with them. Has anyone had any issues with their pythons tearing? Any other suggestions for a good general purpose race tire in a 2.0 size?
