Helix Core E*Spec Alloy Crank Arms

Helix Core e*spec cranks upgrade your e-bike with high-end integrity and aesthetics at great value. Engineered for e-MTB strength, so you don’t need to worry about pedal strikes or holding back on your next gravity run. Forged aluminum arms keep you confident on the trail, while alloy self-extracting crank bolts mean efficient routine service and minimum added weight. Added details like pedal washers, molded impact boots, and e-rider preferred shorter lengths deliver all the high-end features you’d expect from a crankset well over its price.
