Helix Race e*spec Alloy Cranks offer a high-performance alternative to carbon fiber for riders who 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 ideal 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 shorter lengths for improved pedal clearance on low BB frame geometries. 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®, DJI Avinox®, Maxon®, Sram®, and Specialized® SL 1.1, 2.2, and 3.1 motor systems. They feature narrow offsets for a traditional MTB Q Factor feel while offering enough clearance for motors and chainstays.
Don’t let the lightweight fool you: Helix Race e*spec Alloy Cranks are tested to our exacting E-Enduro standards, and are suitable for EN17406 Class 5 applications. They come equipped with custom crank boots for heavy hitting, impact-resistant confidence on any terrain.
Cranks for ISIS Spindle Motor Systems are available in 21.5mm and 26mm offsets to customize fit, Q-factor, and ride feel.
26mm offset cranks are optimized for Bosch CX Gen4/Gen5 motor frames, but will fit on all ISIS spindle motors.
21.5mm offset cranks are designed for optimal fit with Bosch SX, Brose S-Mag, DJI Avinox, TQ HPR50 and Specialized 2.2 & 3.1
