CK-1 cranks are Promax’s top-of-the-line carbon crank offering. The race-ready carbon design maximizes strength and minimizes weight. The crank arms spin on a beefy 30mm spindle to increase stiffness and power transfer. These cranks offer direct-mount chainring compatibility for additional weight savings or run them with a 4-bolt 104 BCD chainring adapter, available separately.
