CASSETTE SPROCKET, CS-R8000 11-32T, ULTEGRA, 11-SPD, 11-12-13-14-16-18-20-22-25-28-32T

The big news with the Ultegra CS-R8000 11 Speed Cassette is you now have more gearing options, with one twist. The increased call for overall drivetrain range for road, gravel, road, and endurance cycling prompted Shimano to fully invest the R8000 drivetrain with more capability. You get the standard popular cassette options up to combination to 11-32T, but the twist is Shimano also added an 11-34T to the mix, but built to be stiffer and more durable throughout, and that features cogs, finish and tooth profiling just like R8000. However it has a different build and series name- that is the HG800 11-34T and is not part of the R8000 line.

The new Ultegra RD-R8000 Shadow Rear Derailleur comes in two sizes, SS (short cage), and GS (mid-cage). Cassettes up to 11-30 are compatible with the SS version, while the 11-32 and 11-34 models requires the GS model. This set-up is also fully compatible with Dura-Ace R9000 / R9100 so if you need more gearing on your Dura-Ace bike, you can opt for the Ultegra R8000 GS rear derailleur and wider range cassette options.
