Bought a used Caffeine last year. Very low mileage and use. Shifted fine and all but had a habit of false shifting on the 5th cog down on the cassette under a load(going up hill). Had it to the shop a few times and nothing helped. Called a friend and the first thing out of his mouth was "does it have a Shimano chain on it?" SRAM X7 components on the bike. I looked and sure enough it did have a Shimano chain. Went in to get the chain swapped out and noticed a broken tooth(on another cog that gave me no problems). Decided to change the cassette also.
Unfortunately I didn't get to test the idea of the chain being the problem. Yeah, supposedly it works but...
But it works perfectly now with new cassette and SRAM chain.
Glad to have that behind me. Quite annoying.
