Shimano Ultegra CS-R8000 Cassette Gray, 11x25

Shimano's Ultegra CS-R8000 Cassette is among our top picks for high-level road cycling because like all Ultegra drivetrain components, it's the perennial favorite based on the performance-to-dollars equation. With different demands for drivetrain ranges required for road, gravel, and CX riding, Shimano has created cassette ranges designed to allow the R8000 drivetrain to easily satisfy the needs for a variety of riders. The Ultegra CS-R8000 Cassette ranges as high as 32t, so you can set up the new Ultegra (or Dura-Ace R9100) with the range you need for gravel epics, 4 corner crits, hill climbs, junior nationals, and everything in-between.
