Default Re: Why not smaller chain?

A bike builder here in Santa cruz runs a normal bike chain...he did this by grinding down the teeth on the stock drive cog till they fit, and he modified a normal chainring sprocket to bolt to the rear disc brake mount...he swears by it...a lot less drag when under leg power, and better accelleration and braking under motor power...I would have done this mod to my bike, but I had already spent $50 on an Andy's 34T that I love. But a normal bike chain is plenty strong...have you ever seen the micro chains that run pocket bikes? Those bikes pull way more RPM's and produce more torque, and the tiny chains hold up fine.
