Drop the hammer and keep it planted. This CNC machined 7075 aluminum crankset drives clean power transfer with a 24 mm spindle and a single ring setup built to hold the chain when the road turns ugly. Choose 48T, 50T, or 52T and run it hard.
CNC-machined 7075 aluminum crank arms and chainring for high strength under load

Single ring chainring options: 48T, 50T, or 52T
130 BCD chainring interface, as shown, for solid alignment and stiffness
Plus minus tooth profile, alternating tooth shaping, to help keep the chain locked in

Mirror-polished silver finish that stays sharp and resists corrosion
Built for road and fast gravel rigs that want a straightforward, punchy 1x drivetrain feel. Pair it with your preferred ring size, set chainline clean, and let it rip through rollers, headwinds, and out of saddle surges.
