A weight-efficient and ergometric crank. Race Face uses a multi-stage forging process that alters the alloy’s structure to increase fatigue resistance. Both the spindle-to-pedal offset and the Q factor (AKA tread) are optimized for power transfer and body positioning.
- Made of 7075 alloy hardware
- I-Beam profile improves stiffness and strength
- Chainrings are precision CNC machined, with a proprietary milling process on the tabs that eliminates axial run out to ensure precise shifting
- Spindle is thin walled chromoly, to deliver the necessary strength without excess weight
- Triple wiper seal on bearing keeps grease in and grit out
- Factory-filled with Phil Wood waterproof grease for extended bearing life
- Sizing is 170, 172.5, 175mm
- Bottom bracket shell is 68mm BSA (English) thread only
- Ring configuration is standard 53/39
