Ground-breaking innovation

Light design with great durability

1. The direct and solid contact without roller avoids 5% ~ 8% energy in comparison to a chain with a roller. Engineering the roller as part of the plate makes it stiffer and able to transfer energy more efficiently.
2. The chain is an estimated 5% lighter.
3. Making the roller part of the plate ensures the chain runs closer to the chainrings and cassette. This also make the transmission much quieter.
