Shimano Electronic Shifting|Holiday Shopping|Dura-Ace CS-R9200 Cassette (Silver) (12 Speed) ( HG) (11-30T)

The Shimano Dura-Ace CS-R9200 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.

Features:

• Faster, seamless shifts under maximum pedaling load
• Refined 12 step gear combination provides peak efficiency and accelerating performance for every situation
• Compatible with 12-speed and road 11-speed freehub bodies
• Compatible with the Shimano Di2 12-speed road derailleurs
