Shimano CS-R8101 Ultegra 12-speed cassette 11 - 34T
The Shimano Ultegra CS-R8101 12-speed, 11-34T cassette is a high-performance road choice, offering a wide range for steep climbs and varied terrain. Its Hyperglide+ technology ensures fast and flawless shifting under maximal pedalling force. The rigid alloy sprocket carrier contributes to better power transfer and reduced weight (approx. 345g). Crucially, it remains compatible with a standard Shimano 11-speed road Freehub body.
Features:
- Hyperglide+ sprockets have a computer designed tooth configuration with contoured shift gates, resulting in 1/3 faster shift time than current HG cassettes providing seamless, smooth operation even under load
- 11-34T wide ratio gearing allows a more efficient use of energy
- Sprockets are cut away extensively and drilled to further reduce weight without reducing rigidity
- For use only with Shimano HG L and HGL2 freehubs
- Alloy cassette lockring
- For use with Shimano 12-speed Ultegra and 105 12 Speed derailleurs
- Average weight 345g
