I still get chainslap with 1×10. It helps for a while but then things slacken. The clucth, the chain, plus chainring (narrow wide essential) starts to wear.
On top of that, I’ve been starting to use Squirt lube, but the result is the chain appears to have no lube on at all. It does, it’s just a waxy layer and mostly inside where it’s doing the job, but I feel that adds to noise as the shiny chain rattles against the chainring. At least that’s my theory. If I wiggle the chain I can hear it clunk on the chainring. Didn’t do that with thicker oil lube (just had a horrid oily grinding sound instead when mucky).
Anyway, clutches I think need further refinement. Had a Type 2 that developed the classic knocking noise under suspension compress. That’s now on the hard tail and is okay on there. Next Type 2 decided to keep locking itself forward (not on the lock pin, just would get stuck inside). Needed service basically a year after I’d bought it, but I needed a working mech so I’ve bought another. So far okay, though I’m not convinced it’s always providing the tension required. There’s some fiddling you can apparently do with a bolt inside on Type 2 mechs but not really played with it.
