Punchy starts. Clean power. This CNC machined, hollow crankset is built to take high cadence road runs, then eat rough gravel without folding. 6061 alloy arms keep it solid. A 7075 alloy spindle keeps it tight when you are laying down torque.

Key Features

  • CNC machining with hollow arm design for hard, efficient power transfer

  • 6061 aluminum alloy crank arms with a 7075 aluminum alloy spindle

  • Single chainring setup, choose 40T, 42T, 44T, or 46T

  • Alternating tooth profile for stronger chain bite and fewer drops

  • 24 mm axle platform

  • Includes BB51 bottom bracket for 68 to 73 mm shells

  • Weight 598 g with the 40T chainring

  • Compatibility works with 10 to 13 speed chains

  • Q factor 148 mm, K factor 91.5 mm

  • Matte black finish

Recommended Use

Run it on gravel builds that live between speed and chaos, fast hardpack, choppy backroads, and punchy climbs where every watt counts. Also a clean match for road bikes that want a simple single ring drivetrain and crisp acceleration.

Bottom Line

CNC cut. Hollowed out. Ready to hammer.
