Lol. If I was smart I would take them off before hitting the trails. As it is I don't and bushes, rocks, trees and the like, hit them and knock them loose. On that particular day...after becoming loose, that was the only place it would stay without stopping and digging out the tools.
*Sadly that position is not conducive to riding. Hit a rock which bounce the front end up hitting me in the helmet. Probably would have busted out some more teeth had I not had a helmet. LOL
