- Hope TRex 40T
gold coming here as soon as the mail gets down under, just got the replacement grips for when I take the twisties off (the hardtail may get an X0 upgrade or 1x) just need the damm ring now and the blanking plate for the front mech direct mount.
MTFU and gone 34 despite the terrain here, 32 probably better but I’m not a fast spinner so I still need something top end.Posted 4 years agoNorthwindSubscriber

Would it work with a 2×10 setup with a medium cage rear mech, or would you need a long cage
It’ll need a fantastic amount of chainslack if you want all the gears to be usable. And mainly what it’ll do is give you a gigantic overlap of the big and little rings.Posted 4 years agocampfreddieMember
Fitted this morning. Still a bit of tweaking to do but it works. Fitted the longer b-screw which was supplied as with the standard screw, the cage of the mech was rubbing. Added one set of links to the chain length too.
This is now on my 29er with a 32t narrow/wide on the front. Should be good for pretty much anything now.

It says compatible with XT or XTR cassettes – anyone know why it wouldn’t work with SLX?
Is it because the cog you need to remove is part of the riveted lump on SLX – instead of separate on XT/XTR? – if so, what’s to stop you splitting the cassette down by removing the rivets and re-assembling?
Have done that on other cassettes before to tweak gear ranges/steps.Posted 4 years agoHob NobMember
Just got in from Swinley. Gearing worked really well, except for where I have replaced the 16 with a15……? I can always put the 15 back in, I suppose.
I’ve put one on my wife’s bike, after running a General Lee and putting up with average/poor shifting over half the block, this seems better.
I have noticed they same, the shift from the 15-19 isn’t great, it’s a big jump low down the cassette, so I guess it’s just a bit lazy as the gap is too big for the chain to get picked up on the pickup ramps.
It needs to be feathered with the shifter to work. Everywhere else is mint though.Posted 3 years ago
I also noticed today that after a ride everything is a bit smoother than it was on the stand last night when I fitted the components. Bearing in mind that that involved a new frame and two new cogs into the existing setup,then what I am hoping for is that once everything has bedded in together shifting might be fine across the entire range. I used a KMC X10 chain, but have a niggling doubt that an XT chain might be better. I’m going to try that next. All in all, I must say I’m pleased that the Zee mech works and think the 40T is a good idea. It didn’t really get much use at Swinley, but I know it will in the Alps…Posted 3 years agomattjgSubscriber
Fitted – had to add 2 chain links as was already running a single on the front and 36 at the back. 1 link was insufficient.
Seems to work fine on the stand and up the street, though I am getting the “dropping on backspinning” issue. Likely that’s a set up issue rather than the TRex.
I had to use the supplied longer B-screw, wound all the way in. RM is Shim M786 XT 10 speed.Posted 3 years ago
