Updates from the original Hydra

  • Quicker 0.41° engagement and 60% less coasting drag
  • Tougher metal for the drive ring and an extra tooth on each pawl guaranteeing Hydra2 can easily handle the torque of the most powerful ebike motors.
  • Larger, 5.5mm pawl pockets that dissipate force 26% better, preventing stretching and elongation of the pockets over years of use
  • A 65% thicker axle to dissipate stress more effectively
  • Larger 6903 bearings throughout, a new labyrinth channel and full-contact radial lip seal to keep out elements that cause premature bearing wear
  • A new design to ensure consistent bearing preload, regardless of variations in axle tightness.
