as the title says...but that 49/46 Williams half-step chain ring and the Cyclo 5 speed (big ring is 22T) is just too tough for me to enjoy riding. First off--what were they thinking? be ok for Kansas or Miami, but cant imagine anywhere else that would have worked. So, if I'm going to keep and enjoy the bike, I need to change the drive train. I want to keep it old school. I have a 52/36 cottered crank that would slip right on. So...what to match up to it. What FD/RD and what free wheel whould work (upper 20's to low 30T's.) Not sure if there is anything British that would work, but that not critical...just want to enjoy this oh so British bike, retain its character as much as possible and not die on the hills around here.
