It helps riders seamlessly maneuver rough trails by reducing pedaling shock and cutting shifting times by a 1/3. (vs. previous HG system)

Benefits & Features

  • Better chain engagement, stronger retention, and smoother pedaling provide greater power and confidence over rapidly changing terrain.
  • Definitive up & down shifting in both directions boosts riders’ concentration and acceleration.
  • Ultra-efficient drivetrain with smoother power transmission increases comfort and reduces rider stress.

Micro Spline

Micro Spline offers an aluminium driver body that reduces weight and integrates only with cassettes of the same configuration. Smaller grooves, spread over a larger surface area, limit damage to the construction and increase its life.
