Next year I want to try my hand at mountain bike racing. What I wanted to do was buy a single speed over the winter and use it to race next year, I was inspired by Jericho/WTB team in the 24hrs of Adrenaline race. The reason I'm considering this is because I'm a big strong boy and I tend to leave my bike in one gear all the time anyway when trail riding. I would use my geared bike for racing but it would take at least a $1000 just to get it in half decent shape for racing, its basically the bike shop equivlent of a Walmart bike, really not worth the money it would take. Plus it is really heavy, worse then my free-ride hardtail for weight, which is fine for trail riding but it wouldn't be competative for a race. So I was wondering if I stood a chance of being competative in beginners or sport class on a single speed.
