Tested out the Hope TRex cassette convertor tonight in the mud didn’t miss a beat. Easy to fit.

good to hear, SRAM or Shimano and more importantly what colour?

Black, looks sweet

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.

Anyone know of a shop local to Newcastle with the T-Rex in stock?

Possibly Daft question.

Is the SRAM/Shimano option to fit an SRAM/Shimano cassette or an SRAM/Shimano chain ?

the cassette

mine arrived this morning many thanks 18 bikes, should be set up and riding tomorrow

Have a few arrive for my bikes, however they’re next door and my neighbour is out on site 🙁

Another possibly daft question

Would it work with a 2×10 setup with a medium cage rear mech, or would you need a long cage

This might be some use:

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.

2×10? so 22/24 x 40t gear? Surely that’s just slower than walking?

I’m assuming you whack on a much bigger front pair… 32/44?

just googled them…..how much!… 😯

Got ours installed, tested mine last night and yep perfect, couldn’t even tell I’d altered it from standard.

Just fitted mine as of 5 mins ago – going to give it a good run out after a bacon sarnie

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.

Was thinking I could live without this until I saw the gold version…
Damn you Hope with your shiny parts 🙂

dinnae worry, Shimano will have their own version out before long to bring things back into perspective

Tested mine out yesterday,as smooth as butter very happy with it

First ride on mine today, great piece of kit and didn’t miss the 17t gear at all

Do you need an SGS rear mech or would a GS be ok with a 32t chainring?

Going to try mine with a Zee. If that works, GS should.

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.

It’s easire to split the XTR and the XT as SLX is riveted, yes.

OneUp say theirs will work if you split an SLX on the smaller cogs, so no reason to think a T-Rex would be any different.

Quick one for those that have fitted one, mine seems to drop down if I back pedal, frustratingly can’t seem to sort it on the stand. Perhaps an issue with chain line and bigger sprocket.

Mine does that too, but I’d rather the rear dropped as there are other cogs to catch the chain, than have it drop off of the front (32tNW).

Good point 🙂

Probably because SLX cassettes are only available in 11-28,32 or 34 and not 11-36.

edit: sorry wrong info I was thinking 9 speed 😳

That was close! 😀

Zee FR mech and Hope T-Rex work on my Trance X. Used the longer B screw and had no issues.

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.

Sweet

andysmiff1,
Arent xt and xtr cassette the ones that let you take out the 17t cog. I think the SLX cassette may be formed of different blocks.

I have a gold SRAM one on order. My 40t General Lee adapter is now pretty worn so I’m going to re-instate the unused top spider on my PG1070 cassette along with a T Rex.

There’s a hack to do it.

Glad it seems OK with a Zee. I’ll be looking at one soon, I reckon.

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.

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…

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.
