Hope Tech 40T-Rex
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 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
- Compatible with: Shimano XT and XTR 11-36 10spd cassettes or Sram PG1030, PG1050 and PG1070 11-36 cassettes (15t or 17t sprocket sprocket has to be removed).
