Hyperglide+ Technology

The specially shaped HYPERGLIDE sprockets feature special tooth profiles as well as specifically positioned climbing aids that optimize chain guidance during shifting. This enables a fast, precise shifting function. The redesigned cassette and chain of the HYPERGLIDE+ drive promote the next generation of MTB riding by improving speed, shifting efficiency and smoothness on any terrain. The better chain engagement, stronger grip and smoother pedaling feel provide more power and confidence in fast-changing terrain. Upshifting and downshifting in both directions have been made more defined for better acceleration. The ultra-efficient drivetrain with smoother power transfer increases comfort, cadence and thus reduces stress in the knee joints. A wide range of gears, cassette options and the choice of single or double chainring front support a variety of MTB riding styles, skills and preferences. HYPERGLIDE+ helps riders seamlessly maneuver rough trails by reducing pedal kickback and shortening shift times by one-third.
