Ive been out of the loop for a while,but seeing how im returning back to Chicago after 3 years in LA, Im bring back home a Schwinn Riverside 7 speed thats just dying for some 4 stroke lovin. My problem is that I can't seem to track down a 4 stroke grubee 4g kit cheap enough,let alone a new one with the fixed bearings, if anyone can point me in the right direction Id appreciate it.
