Light design with great durability
- 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.
- The chain is an estimated 5% lighter.
- Making the roller part of the plate ensures the chain runs closer to the chainrings and cassette. This also make the transmission much quieter.
U-Shaped Grease Container
The U-shape in the outer plate stores 133% more lubrication than a chain with a roller.
There are only three components in the roller-less design. Use of materials is minimized and weight is saved.
