• I'm getting chain slap even with the clutch on - it's not grippy enough.

    Take apart the tension spring, clean and regrease, if that gets caked in crud there is not much the clutch alone would do. The tension spring give you the tension, the clutch just dampens the fast twitching motions.

  • I actually have a feeling it's the freehub sticking so whe I'm in a high gear, cranking and suddenly stop, the cassette is spinning still and the top run of chain slackens off. I have the same issue on my Hope gravel wheels because the green seal is a bit shit so the whole thing grips a bit. You don't notice when pedaling but when wheeling the bike, it acts like a fixed gear.

    I'll probably do as you suggest anyway and give it a clean at some point but I'll also have a clsoer look at the freehub.

  • I very much doubt it’s a loose clutch. IME Shimano clutches come way too tight from the manufacturer. I always loosen them off for the same chain holding ability but much less resistance in the shifter.

    Your XT RD has a rubber port that allows it to be adjusted without removing the cover.
