The Hope T-Rex Expander Sprocket is just what you need to upgrade your existing 11-36, 10 Speed Cassette to give you an 11- 40 range. Simple to install, it fits behind your existing cassette.

- Precise matching of the tooth profiles and shifting point’s specific to each cassette;
- Perfect mating of supporting tabs reducing flex and aiding shift performance;
- Lower B-tension adjustment is needed ensuring good shifting throughout the cassette range compared to fitting a 42t
- Compatible with: Shimano XT and XTR 11-36 10spd cassettes and Sram PG1030, PG1050 and PG1070 11-36 cassettes

Excellent product. Worked first time. Easy fit. 50 miles no issues.
Excellent. Not cheap for a single sprocket (more than an entire XT cassette) but it has given me the perfect range of gears for 1x10. Love the single chainring, no front mech, uncluttered bars....
Awesome product helps convert to a 1x10 setup easily along with a zee derailleur
I bought this along with a Hope 32T narrow-wide chainring to convert my bike to 1x10. Like many riders before me, after my first day out on the new configuration I had to ask myself "Why didn't I go 1x10 sooner?"
The weight reduction, ease of maintenance/cleaning, lack of friction/chain slap and the chain security are a no brainer. My bike looks and performs way better than ever before. Using a Zee FR (wide ratio) rear mech with this sprocket, shifting is crisp and precise. I have yet to drop a chain and doubt if I ever will with this set-up. It has revolutionised my riding and I highly recommend this product along with the appropriate chainring.
Excellent piece of kit. I am running this with the Retainer Ring (32T) and am not (yet) missing the granny ring. The drivetrain is now much quieter too.
Great piece of kit, that has made climbing that bit easier now and really easy to fit and setup on a new XT cassette. Fantastic service from Merlin as well.
