Rise and Grind with our lightest cranks ever!
We applied decades of World Cup racing experience to develop our patented design for the lightest production carbon crankset we've ever made!
Lightweight, 30mm spindle, APS preload adjuster, and self-extractor bring the class-leading combo to your door.
- Lightest production crank on the market
- Gen4 cranks have the spindle on the non-drive side of the crank for easier chain guide setup and drivetrain maintenance
- Use a Boost chainring to fit non-Boost chainlines on this 68mm BB crank
- Now includes an 8mm self-extractor, meaning the cranks can be removed with nothing more than an 8mm allen key
- Carbon fiber crank arms and aluminum spindle w/ Quick Connect lockring and Adaptive Preload Adjuster (APS), compatible with all - Quick Connect guide rings
- 385g (73mm w/32T UL chainring), 398g (68mm w/38T UL chainring)
