Shimano 105 CS-R7100 12-Speed Cassette

The Shimano 105 CS-R7100 & HG71012-Speed cassettes are key components of the new 105 12-speed Di2 drivetrain.

These cassettes have an 11-34/36t range, delivering a low gear combination that lets riders take on steeper slopes with greater control.

There is an optimized "sweet-spot" gear for maximum pedaling efficiency, and the new 105 cassette is compatible with 11 speed freehub bodies.

The new Shimano 105 12 Speed di2 groupset brings the benefits of semi-wireless electronic drivetrains to their workhorse line of components.
