It looks well made, and went on easy enough.

It was a bit of a faff setting the B tension correctly, it shifts perfectly with the clutch on the mech disabled, but I had to reduce the tension on the clutch to get it to shift properly with the clutch engaged, which I guess somewhat defeats the point of a clutch mech.

Anyway will see how it goes, but it saved just under a pound in weight off the bike.

What rear mech and cage length are you using? I'm interested to try this myself, running SLX rear mechs on both bikes, one long cage one medium. I imagine the long cage one will work fine at least.

I've been running one for the last few weeks with a medium cage XT mech. Very happy so far - smoother shifting than I expected.

B-tension is screwed all the way in and it just about clears.

Which gear do you get rid of on the cassette when you fit these?

Haven't tested mine enough to shout about it yet but it's very impressive so far. I've a sneaking suspicion I've picked up a weird spacing issue in teh cassette where the 17t was though, it shifts lovely on and off the OneUp but there's a slow shift in the middle of the block. More examination needed.

Oh, I had to replace the b-screw on my XT medium cage mech. But I think the Ragley mechhanger just naturally needs a lot of b-screw, it was already wound out almost all the way. You can fit it from the inside but far easier just to fit a longer one.

Mines in a box ready to go on the new build.
I've pulled at 16t off an 11-32 xt cassette for my DH bike to span that spacing gap.

I prefer the general lee cassette, you get 3 more cogs for £30 more. Dpacing through the gears is better and you dont lose your 17
