Shimano Ultegra R8020 Groupset

The Shimano Ultegra RD-R8000 SS Rear Derailleur creates a reduction in shifting effort at the lever, at the same time remaining sure, quick and precise. Due to the integrated Shadow RD Technology with its race-proven, low profile design, the derailleur is more compact and fits closer to the frame, ensuring less damage in a crash.

Superior choice is at the heart of Shimano's rider-tuned philosophy, and the Shimano Ultegra CS-R8000 11-speed Cassette reflects that philosophy with gear combinations of 11-25T, 11-28T, 11-30T, 11-32T, 12-25T, 14-28T and 11-34T (CS-HG800-11), giving you all the options you need to tune your ride. The Shimano Ultegra CS-6800 11-speed cassettes use Hyperglide sprockets with revised tooth profiles for reduced wear and lightning quick shifts. A rigid aluminum carrier keeps the cogs in check for improved shifting under the most demanding gear changes. The available ratio combinations work extremely well with standard or compact cranksets. 11-32T gear ratio requires the use of a medium cage rear derailleur.
