coaster sprocket question
i ride a coaster conversion, and have had extreme difficulty in getting a sprocket under 17t, so i run a 56t chainring. i still would like a smaller sprocket so i kept looking, then read on sheldon brown's site that modern coaster sprockets are the same as the ones on internal 3 speed hubs. he also has them available for order on his site. the coaster hub i use is a shimano hi-stop and i was wondering if anyone has had any luck with using the sprockets on his site or any other information as to where (besides velosteel) i can get a coaster sprocket under 17t.
thanks in advance
