Why We Like The Race Face Atlas Cinch Crank Arms

When it comes to aluminum cranksets, few can rival the brute strength and total reliability of the Race Face Atlas Cranks. We've run these things on everything from trail bikes to full-on downhill rigs, and after countless rock strikes and season upon season of use they're still going strong. They aren't the lightest option out there, but they are tough, and they come in some sharp-looking anodized colors to spice up your rig.
