SHIMANO ULTEGRA CS-R8101 CASSETTE (12-SPEED / 11-30 TEETH) – REVOLUTIONARY HYPERGLIDE+ TECH FOR ULTRA-FAST SHIFTING
Maximum performance, uninterrupted power transfer, and uncompromising speed: The Shimano Ultegra CS-R8101 12-speed sprocket cassette represents the most modern evolutionary update for high-end road bikes. Equipped with the groundbreaking **Hyperglide+ technology**, this sprocket set ensures seamless, fluid gear changes in both directions. The chain is guided without jolting, even under maximum load in a final sprint or during hard attacks on a steep climb. This allows you to always maintain your cadence in perfect rhythm and concentrate fully on the road.
This highly functional **bicycle cassette** comes in the perfectly graduated road bike version from **11 to 30 teeth**. The precise gear progression allows for the finest adjustments to the route profile. For an optimal balance of weight and durability, Shimano uses robust, nickel-plated steel sprockets mounted on a lightweight, anodized aluminum spider. As a result, the cassette weighs only approx. **291 grams**. A brilliant advantage for maximum flexibility: The sprocket set is fully backward compatible with the proven Shimano 11-speed road freewheel bodies (HG L) and fully compatible with the new 12-speed road freewheel bodies (HG L2).
