Found a deal on a XTR M985 Race chainset.
Comes with a 30/40t combination. Bit weird but hey.
Looking at going single ring on this crankset as already run it on my other crankset.
Going to need an 88BCD Chainring but will the chain device be ok, as heard that it can sit weirdly due to a different Q Factor of these chainsets?
Also, would a 30/40t work with the Swingarm on an Orange Alpine 160 18 inch?
