New Sherpa frame due, what Shimano 10 speed front derailleur do I need.
None just 1X it 😉
Being serious now it depends on what crank you have double or triple.
Also depends on frame tubing as some require a high mount.
Running XT double crankset as my knees wouldn't cope with 1x10 where I ride.
you need a 34.9mm regular clamp with top-pull or dual-pull. I'm building up a slackline with a similar design and you could get away with either high mount (like what i have) or regular mount
