Race Face Era Carbon Cinch Crankarms The dawn of a new Era Made for the rigors of all-mountain riding, at a weight that's in the class of an XC crank, the new Race Face Era Carbon Cinch Crankarms are the toughest carbon cranks Race Face has ever made. This high strength-to-weight ratio maximizes pedaling efficiency and holds up to bumps and scrapes along the way. Race Face is so sure of this, that the Era Crankarms are guaranteed for life. These 483-gram Era Crankarms feature pedal inserts that are bonded directly into the carbon fiber for improved longevity, while innovative stainless steel wear plates on the outside of the crank arms resist shoe rub and add impact resistance. The Era Carbon Cinch Crankarms boast all the performance you want, with the high-level durability you need.
