40 tooth rear sprocket

Post by Studio263 » Thu Jun 23, 2011 4:48 pm

wanted (needed!) - 40 tooth rear sprocket for my C100 project. I know that the answer is bound to be "NO" but here goes: will the 40 tooth sprocket from the C90 ZZ model fit?

It could fit, if the C100 is 428 pitch?

I've measured the chain pitch at 0.482", have you got your numbers the wrong way round?

Alternatively if they do a 13 tooth front sprocket for the C90 I could change the whole lot over, either way it looks solvable.

I know 428 and 420 chains are the norm across the CUb range, but a 482 to me is new! :lol: :lol: :lol:

6v C90 is 428 chain but C100 (as all other Cubs apart from 6v 90) was 420.

39 tooth from 12v C90 is 420, available everywhere and you won't really notice a one tooth change on the rear.
