Hope 40T-Rex Ratio Expander Sprocket
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. Shimano and Sram specific 40T sprockets have been designed allowing benefits that wouldn’t be possible with a larger sprocket size or with a universal type design:
- 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
