SHIMANO Ultegra CS-R8100 Di2 System Silver Cassette 12-Speed

SHIMANO Ultegra CS-R8100 Di2 System Silver Cassette 12-Speed

*** For Di2 Shifting Systems Only ***

The Shimano Ultegra CS-R8100 Cassette brings Hyperglide+ technology to the road. Hyperglide+ allows for better shifting under load so it is no longer necessary to ease up on the pedals when making a shift. For simple compatibility, Shimano 12-speed road cassettes fit on the same hub body as 11-speed road cassettes. This allows riders to use their current wheels for 12-speed. Shimano also managed to add the extra sprocket without increasing the total weight of the cassette.
