Shimano Ultegra CS-R8101-12 cassette

  • The Shimano Ultegra CS-R8101 cassette is characterised by seamless shifting processes that not only ensure quiet cruising, but also allow the rider to devote their full concentration to climbs and sprints. This is made possible by the Hyperglide+ technology which has already been able to convince in the MTB segment with smooth shifting processes in both directions across the entire gear range.
  • Even under maximum effort or in a direct duel with the opponent, smooth upshifting and downshifting can be realised, while larger teeth maintain maximum efficiency. And the 12-speed cassette is even compatible with Shimano's previous 11-speed freewheel bodies.
  • Sprocket ratios: 11-12-13-14-15-17-19-21-24-27-30-34 teeth

    Hyperglide+

  • The conventional Hyperglide technology ensures smooth shifting upwards thanks to small shifting ramps, which guide the chain towards the next larger sprocket. Also Hyperglide+ uses this functionality but applies it in the opposite direction, too, preventing the chain from falling down when shifting downwards. The result is a smooth and consistent shifting in both directions, free of vibrations and without disrupting the cadence.

    Only treat we give our baby!!!
    Flavor Name: Sweet Potato, Size: 1 Pound (Pack of 1)
    These are all natural treats that our dog loves. Each bag is different, so I know they are freshly made, not like other treats that are all the same shape and color. If you love your dog, you need these. I even send them to my granddogs.
