E.THIRTEEN E-SPEC HELIX RACE ALLOY E-Bike Cranks for Specialized M30 SL1.1 Silver

The E.THIRTEEN E-SPEC HELIX RACE ALLOY e-bike cranks are a premium aluminium alternative to carbon for e-bikes, offering lightness, robustness and aesthetics without compromise. Forged then precision CNC machined, they combine performance and design, perfect for demanding cyclists looking to optimise their e-bike setup.

Designed to withstand impacts and pedal strikes, they are available in shorter lengths to improve clearance on frames with low bottom brackets. The integrated aluminium extractor system makes fitting and maintenance easier. The result: weight savings, improved reliability and simplified maintenance.

Compatible with a wide range of motors (Bosch®, Brose®, Yamaha®, Fazua®, Sram®, Specialized® SL…), they maintain a feel close to the Q Factor of a standard mountain bike, while providing sufficient clearance for the motor and chainstays. Tested to E-Enduro standards, they are ready for the most extreme terrain, with crank guards included for maximum durability.
