I'll reply from the other end. I'm not a racer, but when the right one comes around, I'll do it.
Going down a steep, dry, powdery chute, I slid off course when I saw a downed guy ahead of me. I stayed upright, but the bike hit a tree stopping me in a trackstand. The brake lever was up against the tree. I jumped off my pedals and walked down to the guy. Both of us were alright. I was probably doing only 3-5mph when I hit the tree. I'm lucky that tree was there though! Anyway, the guy was OK and rode down. The marshall then opened it up. I adjusted my lever since I leave them loose for this reason(no wrench necessary). I saw an opening and jumped in. I checked the brakes at the bottom and did a check up on the bike. Everything was fine. I did 2 practice runs to finish off my day, 2 practice runs the next morning and my race run to finish off my weekend.
Once home I wanted to clean the bike up and move my levers in more. WOW! There was a gouge in the bar that was thru the powder coating and into the aluminum about the thickness of 2 business cards. It was a FUNN Fatboy. I thank God it didn't break. I made it a point to build up my bikes with FUNN components though. If it were carbon?.... Ttyl, Fahn
