Once again an old Schwinn Varsity! So im wondering can someone help me how do i make the bike able to use a 3 piece crank instead of the 1 piece? and Whats better do you think? Would a 1 piece be good on a fixie or is a 3 piece better? Because if i stick with a 1 piece i can find pedals that a clip adaptable online for cheap but then again i have a 3 piece crank and orgin 8 track pedals? What do i need to make the conversion and what would be better cost wise? Thanks for your help!
