"What Our Gearhead® Experts Are Saying: ""I’ve run these specifically on ISIS-equipped E-Bikes, and they strike an impressive balance between weight and durability. The stiffness under motor-assisted load is excellent, and the stainless wear plate really helps with heel rub on wider motor platforms. If you want carbon cranks that are actually built for ISIS E-Bike systems, these are hard to beat.""When we’re putting serious power down on long, assisted climbs and riding aggressively on the way back down, the Race Face Era E-MTB Crankarms deliver a refined, confidence-inspiring ride feel. Designed to handle the added torque and stress of modern E-Bikes, they bring carbon performance to platforms that demand more from every component. From sustained trail rides to technical enduro lines, they help our E-Bikes feel lighter, smoother, and more precise. Built with a high-end UD carbon layup, the Era crankarms are reinforced with a stainless steel wear plate to protect against heel rub and trail damage common on wider E-Bike motor interfaces. Optimized for ISIS spline standards, they integrate cleanly with systems like Bosch and TQ, delivering efficient power transfer and stable pedal ergonomics."
