e*thirteen is proud to announce the launch of the rugged and handsome Helix Race e*spec cranks and chainrings designed to fit Bosch CX and SX motors.
Advanced durability and refined style for your EMTB’s drivetrain
With the increasing popularity of eMTB, e*thirteen recognized the need for high-performance drivetrain components that are tailored to the rigorous requirements of electric motor systems, yet are still beautifully designed. The Helix Race e*spec cranks and chainrings are engineered with precision and durability in mind to not only enhance the performance and reliability of e-bike drivetrains, but are available in colors so you can customize your ride.
While the chainring is designed specifically for Bosch CX and SX, the cranks do fit all motors based on ISIS Drive spindles. That also includes TQ HPR50, Brose, Yamaha, Maxon, and Specialized 2.2 motors.
