I have made a decision, any advice is greatly appreciated!!
Thanks for all the advice so far, and the links were VERY helpful. As I mentioned I am a truck driver and keep the bike with me to ride. What I didn't mention is that i also have a 7yo son who travels with me full time, I have custody of him. So I have decided to build 2 bikes out of the frames I have, a Gary Fisher and a Haro. They are both going to be the same.. single speed, freewheel, front disc brakes. I may have to use shorter cranks for my sons bike but I think I can make it work. Any info, parts recommendations or parts for sale would be greatly appreciated.
