Rebel against scuffing

The wider frame width needed to accommodate electric motors and the narrow stance needed for pedal ergonomics means shoe rub is increasingly prevalent on eMTBs. Era’s unique stainless steel wear plate protects against this damage. Keep your cranks looking fresh after spinning up all those pedal-assisted climbs, all while adding additional impact protection.

Lifetime Warranty. Crashes Included.

We made this carbon e-bike crank so strong, so stiff and so durable we are backing it up with a Lifetime Warranty inclusive of crashes. Let ‘er rip. Our cranks can take it.

Resonate with your ride

The Era eMTB crankset saves grams while staying scuff-free and looking great. It’s also available in a shorter 160mm length to avoid those pesky pedal strikes. Optimized for ISIS (e.g. Bosch Gen 5 CX, TQ HPR50) and ETOR (e.g. Fazua Ride 60) spline standards. Cruise up for another lap and let your cranks do the talking.

Frequently asked questions

Are shorter crank arm options available to prevent pedal strikes?

Yes, the Era eMTB Crankarms are available in shorter lengths specifically to help minimize pedal strikes on technical terrain.

Available lengths are:

  • 160mm (Recommended for maximum pedal strike prevention)
  • 165mm
  • 170mm

Offering the 160mm length addresses the increased load requirements and design constraints of full-power e-bikes while improving overall pedaling ergonomics.

Are these cranks durable enough for full-power e-bikes?

Yes, the Era eMTB Crankarms are specifically engineered to withstand the unique demands of full-power electric mountain bikes. They are designed to handle the increased loads and forces associated with powerful e-bike motors. Constructed from UD Carbon, they provide superior strength and stiffness while maintaining a lightweight profile (370g for 165mm arms).

For ultimate confidence, these cranks are backed by a comprehensive Lifetime Warranty that includes accidental damage from crashes.

Can I trust the carbon durability during crashes?

Absolutely. Race Face stands behind the engineering of these cranks with a comprehensive lifetime warranty that explicitly covers damage sustained during crashes. They are built using robust UD Carbon specifically to handle the high torque and forces of aggressive eMTB riding.

Do these crankarms include protective boots?

Yes, the Era eMTB Crankarms come with protective Crank Boots included in the box. These boots are specifically designed to shield your crankarms from impact and trail debris. If your boots become worn over time, they are replaceable to help keep your cranks looking and performing their best.

Are the carbon crankarms protected from shoe rub?

Yes, the Era eMTB crankarms are specifically engineered for durability and feature integrated protection against shoe rub, a common issue on eMTBs.

  • Stainless Steel Wear Plate: The inner surface of the carbon arm includes a unique stainless steel wear plate.
  • Protection: This feature actively protects the UD carbon material from friction and impacts, helping to keep the cranks looking new over time.
What does the lifetime warranty actually cover?

The Era eMTB cranks come with a comprehensive lifetime warranty that specifically includes coverage for damage sustained during crashes. This provides significant peace of mind for riders pushing their limits on technical terrain.

Lifetime Warranty, Crashes Included.
