anybody had just this gear make strange noises? all my other gears shift and make no noise (not even griding in the peak grit), bar the 42cog
I’m running a absolute black oval chainring, kmc x11sl chain and x1 cassette/xt 11speed rear mech, chain length fine, b-tension fine etc
all shifts are crisp etc, but when wynching up long slogs if I use the 42c it makes a kind of pulling/jumpy type noise just in the 42cog, drop down the next and instantly goes, its there every other revolution and as said its like a jumping/pulling type noise (as though it sounds like it skipping but actually doesn’t)
any ideas? its a fair old mix of brands/components though I’m 99.9 sure it didn’t do it when I first had it all (don’t really use the 42very often)
