SHIMANO CS-R8101-12 (ULTEGRA) | 12-speed Cassette Sprocket for High-Speed Shifting and Efficient Gear Ratios
Smoothly responds to all pace changes.
The SHIMANO ULTEGRA R8100 series "CS-R8101-12" is a 12-speed road cassette sprocket adopting HYPERGLIDE+ technology.
The refined 12-speed configuration supports efficient cadence maintenance in a wide range of situations, from racing to long rides. It demonstrates smooth and quick shifting performance even under high load, such as during acceleration or climbing.
The adoption of HYPERGLIDE+ achieves an even more natural shift feel than before. The chain moves quickly to the sprocket, allowing for comfortable shifting without stopping pedaling.
Furthermore, it is compatible not only with new generation 12-speed road freehubs but also with existing 11-speed road freehub bodies. The ability to upgrade to the latest 12-speed system while utilizing existing wheel assets is also a major appeal.

Among the R8100 generation ULTEGRA, the CS-R8101-12 particularly stands out for its high level of perfection.
Thanks to HYPERGLIDE+, shifting is incredibly smooth even while pedaling. Especially when downshifting on climbs or shifting gears to respond to an attack, there's minimal shift shock, maintaining your riding rhythm.
The 11-30T is recommended for races and predominantly flat rides, while the 11-34T is ideal for hill climbs and long rides. The fact that some wheels can still use an 11-speed freehub body is also a welcome point.
This 12-speed sprocket is a highly refined product that truly allows you to experience the shifting performance characteristic of the latest ULTEGRA.
