The Helix Race espec 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 fully CNC-machined, the Helix Race espec cranks are a work of mechanical art, designed to customize your fit and ideal e-bike setup.
These cranks represent a significant upgrade that will increase strength and resistance to pedaling shock while reducing the weight of your bike. They are available in shorter lengths for improved pedal clearance on frames with low bottom bracket geometry. They feature integrated, self-extracting alloy crank bolts for easy installation and removal during maintenance.
Compatible with Bosch®, Brose® S Mag, TQ®, Fazua®, Yamaha®, DJI Avinox®, Maxon®, Sram®, and Specialized® SL 1.1 and 2.2 motor systems. They feature narrow offsets for a traditional mountain bike Q-factor feel while still providing ample clearance for motors and chainstays.
Don't let their light weight fool you: the Helix Race e*spec alloy cranks are tested to our demanding E-Enduro standards and meet EN17406 Class 5 applications. They come equipped with custom crank protectors for unwavering confidence on any terrain, even during hard impacts.
This 26.5mm offset crank version is optimized for Bosch CX Gen4/Gen5 motor frames but will fit all ISIS-axle motors.
