Went 1x and needed extra high range for climbs. Have a slx 10 speed cassette and this plus the lock ring was my only option. Easy installation plus looks great and functions smoothly. Must tighten the b-screw to push the derailleur where it should be. Just used the new setup recently and was very satisfied with its function.
