Shimano CS-R7100 105 12-Speed Cassette

Made to match the R7100 groupset, Shimano’s 105 12-Speed Cassette offers fantastic shifting performance and a wide range of ratios. With a 34t largest sprocket even the steepest hills won’t be a problem and the Hyperglide+ technology ensures that every gear change is crisp and quick. As it has 12 sprockets, it allows for better cadence control with fewer gaps between the gears with the nickel-plated finish providing protection against wear and corrosion. The cassette is compatible with 12-speed and road 11-speed freehub bodies.

  • Close ratio gearing allows more efficient use of energy through finer cadence control
  • Largest sprockets are mounted on a lightweight alloy carrier to reduce weight and increase rigidity
  • Sprockets are cut away and drilled to further reduce weight without reducing rigidity
