Find the gear ratio that’s right for you at Escapa.
TheShimano Ultegra CS-R8101 12-speed cassette has set new standards for off-road riding with its smooth upshifts and downshifts across the entire gear range. For the Ultegra 8101 groupset, the Japanese manufacturer has also adopted this technology for Carrera bikes.
Even when pushing hard on climbs or sprinting toward the finish line, you can now shift gears without hesitation. This is made possible, in part, by the longer teeth. Despite the new design and the additional 12th sprocket, the CS-R8100 cassettes are compatible with previous 11-speed Road freehub bodies.
