R7101 105 12 Speed Cassette

The Shimano 105 12-Speed Cassette brings Hyperglide+ shifting technology to the 105 groupset, delivering the crisp and reliable gear changes under load that the system is known for through a computer-designed tooth profile with contoured shift gates.

Close ratio gearing gives you finer cadence control across the range, the largest sprockets sit on a lightweight alloy carrier for rigidity without unnecessary weight and a nickel-plated finish across the sprockets provides solid corrosion resistance for regular all-weather use.
