CEBEP, I thought your chain rubbing problem was with the original, medium elastomer? Could the new harder elastomer allow 34-36t?
If not, it might be possible to raise the swingarm just enough by inserting a shim of a hard material between the elastomer and the swingarm. This must be done with great care and in small millimeter increments, and it may void the warranty. But done carefully it could allow you to use the 36t.
I installed hard elastomer after cassette was was installed so I can’t say. Still I assume elastomer will deform a little after usage and/or loading the rear with 15kg of bags and the last thing I want is it starting to rub again. My mechanic offered to leave the bike to him so he can experiment with different cranksets but I didn’t want to spend anymore time or money on it. 32t is after all a factory wide cog so I thought I’d just leave it at that. I’ll use it the way it is and see if 32t is enough for where I ride.
