For a 1x on a mountain bike (even for minimal gnar) probably yes, as a dropped chain is sooo annoying and potentially mech-destroying. This was my 1x 9spd set up after a spin in Ashton Court - awesome trails - and prompted my move to 1x (2nd hand) 10spd:
Would you say a clutch mech is worth it? I’m happy to have a mish-mash of parts and it’ll likely be 2nd hand all the way.
