The Atlas crank arms from Race Face are specifically designed for use in trail, enduro, downhill, dirt jump, and BMX riding. Made from high-quality, CNC-machined aluminum, they offer a combination of lightness and durability that is essential for demanding mountain biking. Weighing only 690 g (at 175 mm length and 32 DM), these crank arms are engineered to maximize performance and efficiency while riding. The Cinch interface allows for easy mounting of a spider or single chainring, while providing ample clearance for various wheel sizes (27.5", 27.5"+, 29"). Compatibility with Boost standards and various bottom bracket types (BB92, PF30, BSA) makes the Atlas crank arms a versatile choice for different bike configurations. Please note that bottom brackets and chainrings/spiders are not included.
