Do you know the manufacturer of your casesaver, Jerry ?

I would much rather stick with 15/39 if I can get a casesaver in there with enough clearance.

Also, it turns out that 15/39 with a 98 link chain is an ideal combo for evening out wear in the final drive ... it takes 15 full chain rotations before a tooth on the front sprocket returns to a link with which it has previously engaged ....and 39 full chain rotations in the case of a tooth on the rear sprocket.
See here for a calculator ...https://www.blocklayer.com/chain-sprocket.aspx

The 14t front sprocket fares much worse in those stakes.
Fortunately I think the 98 link chain will do for either set-up, so I can still switch back to the 15t if I can solve the casesaver issue.
