Details
The Hope T-Rex ratio expander allows you to upgrade your existing 11-36 10spd cassette to give an 11-40T range.
- The T-Rex simply installs behind your existing cassette and replaces one of the smaller sprockets, usually 17T.
- Shimano and Sram specific 40T sprockets have been designed, this gives us the following benefits which wouldn't be possible with a larger sprocket size or with a universal type design…
- Precise matching of the tooth profiles and shifting points 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
