Sunrace I-Crank MTB Left Crank Arm 170mm

Select SUNRACE mountain bike cranks and bottom brackets for square taper or integrated axle

Sunrace cranks include the 170 mm aluminum I-Crank left crank arm and the 175 mm MX crankset with an integrated axle for 11–12 speed single chainring drivetrains, also 10-speed compatible depending on configuration. The MX crankset uses a 96 mm interface diameter for chainring mounting and comes with its cups to ensure correct alignment on a suitable bottom bracket. The aluminum construction guarantees sufficient rigidity for modern mountain biking, in single chainring setup. Set suitable for replacement or assembly without chainring. PSB Cycle Parts.
