Key feature
The Shimano HyperGlide+ cassette has revolutionised shifting with smooth transitions both up and down the gear range. Today, it's time for this technology to transform road cycling. Even during maximum efforts on climbs, there's no need to ease off the pedals to make a shift. Regardless of the gear ratio selected, the Shimano CS-R8101 drive train maximises efficiency.
