Tonight i went out riding with some friends and we got on to a long road no cars i knew they were going to take off so i went and when i got up to where i was going to switch from 2nd to 3rd my handle bars just went wild i just hit my front brake and hoped i didnt wreck but i dont know how it happend? I think there might of been a little 5inch climb on the street then went to being straight after that, my front wheel must have just barly came off the ground when i switched gears and then went crazy scared the shit out of me, i was going pretty fast, but is my bike ok or should i go get it looked at? It never happend to me in 4 years of riding, what do u guys think happend?
