HYPERGLIDE+
The redesigned cassette and chain of the HYPERGLIDE+ drivetrain represent the new generation of MTB touring - with improved speed, shifting efficiency and smoothness on any terrain.

Advantages and features

• Better chain retention, greater holding power and smoother pedalling provide more power and a safer riding experience in rapidly changing terrain conditions.
• The clearly defined upshifting and downshifting in both directions promotes the rider's concentration and supports acceleration.
• The highly efficient drive with more even power transmission ensures greater comfort and less stress.
• The wide range of gears and cassettes and the combination with one or two chainrings offers support for many different MTB riding styles, experience levels and preferences.

HYPERGLIDE+ is the launch pad for the new generation MTB experience, as it enables smooth pedalling on virtually any terrain for the first time, while the completely redesigned drive system with its specially developed chain enables faster shifting, efficient power transmission and unprecedented chain stability. It precisely determines the optimum moment for the gear change and thus ensures smooth operation. This makes it easier for riders to adapt to abruptly changing terrain conditions. HYPERGLIDE+ helps riders to master rough trails with confidence. It dampens the pedal stroke and reduces shifting times by a third (compared to the current HG system).
