Hope 40T-Rex Ratio Expander Sprocket - Black

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
