Find the gear ratio that’s right for you at Escapa. The Shimano Ultegra 12-Speed Cassette CS-R8100 has set new standards for off-road use with its smooth upshifts and downshifts across the entire gear range. For the Ultegra 8100 groupset, the Japanese manufacturer has also adapted 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, among other things, by the longer cogs. Despite the new design and the additional 12th cog, the CS-R8100 cassettes are compatible with previous 11-speed road freehubs.
