Fuji Track / Fuji Track Pro / Fuji Track Classic

put a 19t on the rear and you'll have 19 skid patches, easier and cheaper than getting an 49 chainring which give you 1 less skid patch.

The thing is I love my gearing at the mo, I thought of going to a 19 but it would be that little bit too low, so I thought when my 48 wears out get a 49 and go down to 17, thus keeping a closer gearing to what I like and getting more skid patches(I think).Plus 49 will be better for me getting into track racing.
