E*thirteen Helix Race E*spec crank arms

High performance and confidence on any terrain.

Helix Race e*spec Alloy Cranks offer a high performance alternative to carbon fiber for riders that prefer alloy or don’t want to pay for carbon to get a premium product. Forged and extensively CNC finished, the Helix Race e*spec Crank is a piece of machining art to personalize your fit and dream e-bike build. These cranks are a serious upgrade that will increase strength and pedal strike resistance while reducing your bike’s weight. Available in eMTB rider-preferred lengths for improved pedal clearance on low BB frame geos. Equipped with built-in alloy self extracting crank bolts for ease of installation and removal when it’s time to service. Compatible with Bosch, Brose S Mag, TQ, Fazua*, Yamaha, Maxon and Specialized® Brose motor systems using the 24mm ISIS standard. They feature narrow offsets for traditional MTB Q Factor feel while offering enough clearance for motors and
chainstays. Don’t let the light weight fool you. The Helix Race e*spec Alloy Cranks are tested to exceed E-Enduro EN17406 Class 4 standards and come equipped with custom crank boots for heavy hitting, impact resistant confidence on any terrain.
