SHIMANO ULTEGRA CS-R8100 CASSETTE (12-SPEED / 11-30 TEETH) – REVOLUTIONARY HYPERGLIDE+ SHIFTING PERFORMANCE FOR HIGH-END ROAD BIKES
Maximum performance, uninterrupted power transfer, and uncompromising speed: The Shimano Ultegra CS-R8100 12-speed cassette ushers in a new era in road cycling. For the first time, the groundbreaking **Hyperglide+ technology** makes its way into the Ultegra road bike group. Thanks to intelligently placed shift ramps and optimized tooth profiles, the chain is guided absolutely smoothly during both upshifts and downshifts. The result is unbelievably fast, smooth, and shock-free gear changes – even under maximum load in a final sprint or during tough attacks on a steep climb.
This highly functional **bicycle cassette** impresses with its first-class material components and perfect gradation from **11 to 30 teeth**, which always guarantees the optimal cadence. While the robust sprockets made of noble, nickel-plated steel ensure extreme durability, the lightweight, anodized aluminum spider reduces the total weight to a slim approx. **291 grams**. A brilliant trick for wheel upgrades: The innovative sprocket design is fully compatible with the new Shimano 12-speed Road freehubs thanks to the dual HG L / HG L2 splining, and also backward compatible with proven Shimano 11-speed road bike freehub bodies.
