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 restraint on your next gravity run. Forged aluminium arms provide a secure feel on the trail, while the aluminium self-tapping crank bolts allow for efficient routine maintenance with minimal extra weight. Additional details such as pedal shims, moulded impact guards and e-rider preferred shorter lengths offer all the high-end functions you'd expect from a crankset that far exceeds its price.
