quick question for anyone with experience/knowledge on this - I ordered a Shimano XT M771 dual pull front MTB derailleur - the website at the bike shop said it was 44/48T compatible.
Just installing it now and reading the instructions that came with it, I noticed the M771 says 44T only (and my front big chainring is 48T - m770 series). Is this actually an issue? Should it be fine, or should I expect issues, and if so, what are they? Is there a workaround?
'''96 Litespeed Catalyst, '05 Litespeed Firenze, '06 Litespeed Tuscany, '12 Surly Pacer, All are 3x8,9 or 10. It is hilly around here!
If it is indeed designed for a 44T maximum chainring the curve of the cage will be a bit tight for a 48T so you will have to mount it higher than optimum to clear the ring. Shifting should be ok if not perfect. Just mount it as close to the big ring as you can and see how it works.
