I have an old wheelset with a 16T cog. It's currently a 120mm flipflop hub, and I'm going to be replacing it with a 120mm coaster. The coaster hub that I want doesn't come with a 16T cog (only 14, 15 and 17 for some reason).
Rather than mess around with chain tension, etc, I was wondering if I could just use the cog from the old wheelset on the new hub, or if it's more complicated than that.
More info: old hub is a 32H, 14G, 16T cog. New hub is a velosteel 32H http://www.elegantwheels.net/STORE.html
