Do you think it is a bad idea to single track mountain bike with a professional bmx "race" bike. It seem to be physically punishing. the last time i rode my back got all jacked up. what kind of safty gear?
You're kidding right?....Sure I suppose you can but its your body, how long do you need it for? Yes, it is a bad idea to use that bike. This is why they make 26" and 29er size wheels and mountain bike frame/ fork bikes. Would you use a VW bug at Daytona? sixsixone makes some of the best safety gear on the market as well as Fox racing what more do you need to know?
