- 5-Arm x 135mm P.C.D.
- Compatibility: 10/11 Speed Campagnolo (Super Record - Record - Chorus - Athena Alu)
- Material: CNC machined 7075 T6 alloy.
- Coating: CERAMIC top layer impregnated with TEFLON®.
- Colour: Matt black.
Adding CERAMIC ensures a harder surface, longer life, resistance to scratching and the TEFLON® reduces the chain's friction coefficient by over 80% and makes for diminished noise factor, lower over all friction, less need for lubrication and optimized indexation between chainrings.
