Helix Core e*spec cranks give your e-bike an upgrade with high-end integrity and aesthetics at a great price. Designed for e-MTB strength, so you don’t have to worry about pedal strikes or holding back on your next gravity run. Forged aluminum arms provide a secure ride feel on the trail, while self-extracting aluminum crank bolts allow for efficient routine maintenance with minimal added weight. Additional details like pedal washers, molded impact protection sleeves, and preferred shorter lengths for e-riders offer all the high-end features you would expect from a crankset that far exceeds its price.
