Shifting the Extra into Speed

New Definition –
World’s Lightest Bike Chain

Take Advantage of Light Weight 40% Efficiency higher than that of the classic chain.

  1. A roller is constructed on the inner plate.
    The direct and solid contact avoids 5% ~ 8% energy losses in transmission when compared with that of a roller separated from its neighboring parts. The co-shaped structure helps to pedal forces effectively passing on.
  2. Reduce the use of material and waste. An estimated 15% chain weight reduction is achieved.
  3. A precisely constructed roller ensures close proximity to chainrings and chain wheels. The chain is enhanced fluently, silently rolling over the drivetrain system.


  • Three Components
  • Grease Contain Region for Lubrication
  • Quiet Performance on the Rollerless Inside

U-Shaped Grease Container

The grease keeping place renders continuous lubrication support and provides the best chain running performance. Surely reduce maintenance frequency and service needs.

360° all-direction riveting strength

provide high pin power, firmly attached to the outer plate. Overall secure the riveting structure without any break risk.
