Shimano Ultegra CS-R8101 Cassette Description:

The Shimano Ultegra CS-R8101 Cassette utilizes Hyperglide+ technology allowing 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.

Features:

• Refined 12-step gear combination provides maximum efficiency and accelerating performance
• Compatible with 12 speed Shimano Di2 and mechanical shifting systems
• Compatible with 12 speed and 11 speed freehub bodies
• Faster, seamless shifts under maximum pedaling load
