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.\u003c\/p\u003e\n\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\n\u003cp\u003eProduct Details \u0026amp; Features\u003cbr\u003e\n• \u003cstrong\u003eHyperglide+ System:\u003c\/strong\u003e Consistent, shock-free gear changes in both directions without interrupting propulsion\u003cbr\u003e\n• \u003cstrong\u003eRobust Material Mix:\u003c\/strong\u003e Nickel-plated steel sprockets on a weight-optimized, anodized aluminum carrier (spider)\u003cbr\u003e\n• \u003cstrong\u003eDi2 Optimization:\u003c\/strong\u003e Developed for the electronic 12-speed rear 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-R8100 (Ultegra R8100) | \u003cstrong\u003eGear Steps:\u003c\/strong\u003e 12-speed | \u003cstrong\u003eGradation:\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 Number:\u003c\/strong\u003e ICSR810012130 | \u003cstrong\u003eGTIN (EAN):\u003c\/strong\u003e 4550170893767\u003c\/p\u003e\n\n\u003cp\u003eScope of Delivery\u003cbr\u003e\n1x Shimano Ultegra CS-R8100 12-speed Cassette (11-30 teeth) including original aluminum lockring.\u003c\/p\u003e\n\n\u003cp\u003eConclusion\u003cbr\u003e\nThe Shimano Ultegra CS-R8100 cassette is the ultimate upgrade for demanding road cyclists and Di2 enthusiasts.
