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.\u003c\/p\u003e\n\n\u003cp\u003eThis 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).\u003c\/p\u003e\n\n\u003cp\u003eProduct Details \u0026amp; Features\u003cbr\u003e\n• \u003cstrong\u003eHyperglide+ System:\u003c\/strong\u003e Consistent, shock-free up and down shifting without interruption of propulsion\u003cbr\u003e\n• \u003cstrong\u003eRobust Material Mix:\u003c\/strong\u003e High-quality, nickel-plated steel sprockets on a weight-optimized aluminum carrier\u003cbr\u003e\n• \u003cstrong\u003eDi2 System Integration:\u003c\/strong\u003e Perfectly matched to the electronic 12-speed derailleurs RD-R8150 and Dura-Ace RD-R9250\u003c\/p\u003e\n\n\u003cp\u003eData \u0026amp; Identification\u003cbr\u003e\n• \u003cstrong\u003eBrand:\u003c\/strong\u003e Shimano | \u003cstrong\u003eModel:\u003c\/strong\u003e CS-R8101 (Ultegra Series) | \u003cstrong\u003eGear Steps:\u003c\/strong\u003e 12-speed | \u003cstrong\u003eGraduation:\u003c\/strong\u003e 11-12-13-14-15-16-17-19-21-24-27-30 T\u003cbr\u003e\n• \u003cstrong\u003eFreehub:\u003c\/strong\u003e HG L (Road 11\/12-speed) \u0026amp; HG L2 (Road 12-speed) | \u003cstrong\u003eWeight:\u003c\/strong\u003e approx. 291 g | \u003cstrong\u003ePart No.:\u003c\/strong\u003e ICSR810112130 | \u003cstrong\u003eGTIN (EAN):\u003c\/strong\u003e 4550170849894\u003c\/p\u003e\n\n\u003cp\u003eScope of Delivery\u003cbr\u003e\n1x Shimano Ultegra CS-R8101 12-speed cassette (11-30 teeth) including original, anodized aluminum lockring.\u003c\/p\u003e\n\n\u003cp\u003eConclusion\u003cbr\u003e\nThe Shimano Ultegra CS-R8101 cassette is the ultimate performance component for ambitious road racers and Di2 enthusiasts.
