Need to choose crankset for 135mm rear hub of MTB I replaced older 8 speed cassette on my Cannondale Trail with new Shimano Deore M6000 10 speed cassette (11-42). But since the axle spacing is of older type, want to get a matching crankset (2x preferred). Any suggestions?
Deore M6000 crankset I presently tried, but has chainline issue.
You can look up the specs of Shimano cranks here: https://productinfo.shimano.com/#/spec/MTB/Front%20Chainwheel.

The tables give the OLD (over locknut distance) aka rear hub spacing for each crank. Most are for 142 or 148mm.

Many cranks for 142mm rear spacing have a chainline of 48.8mm, which is just over the old standard of 47.5.mm for triple cranks on 135mm spacing, so any of those should be fine. You just want to avoid cranks with chainline of 50mm or or more.
