Why our Vert Junkies® love this

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.
