Shimano CS-R8101 Ultegra 12-speed cassette 11 - 34T

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
