e*thirteen Helix Race E*spec Crankarms - Bosch Gen4 / Brose S Mag / TQ HPR50 - 26.5mm Offset - bronze

Made from lightweight, high-quality aluminum, the E*thirteen Helix Race crankset is an affordable and powerful alternative to carbon cranks. Forged and CNC machined, these cranks are the perfect upgrade for your e-bike. Not only are they strong enough to withstand hard impacts, but they also reduce the weight of your mountain bike. They also have built-in, self-extracting aluminum crank bolts for easy assembly and disassembly for service.

The Helix Race e*spec cranks are designed to exceed E-Enduro EN17406 Class 4 standards. In addition, they feature custom crank boots that provide greater protection against hard impacts and shocks on any terrain.
