The fine, revised gradation of the Shimano CS-R7100 sprocket set ensures not only optimal acceleration in all situations, but also excellent efficiency, so that no pedaling energy is lost. Even under maximum load, with this sprocket the shifting process is faster and feels so smooth that gear changes are hardly noticeable. With a ratio of 11 to 34 teeth, moreover, neither sprints on the flat nor steep climbs are a hurdle. In addition, the 12-speed cassette is also compatible with Shimanos previous 11-speed freewheel bodies.
