HELIX RACE E*SPEC ALLOY CRANK

HIGH PERFORMANCE. CONFIDENCE ON ANY TERRAIN.
Helix Race e*spec Alloy Cranks offer a high performance alternative to carbon fiber for riders that prefer alloy or don’t want to pay for carbon to get a premium product. Forged and extensively CNC finished, the Helix Race e*spec Crank is a piece of machining art to personalize your fit and dream e-bike build.

These cranks are a serious upgrade that will increase strength and pedal strike resistance while reducing your bike’s weight. Available in eMTB rider-preferred lengths for improved pedal clearance on low BB frame geos. Equipped with built-in alloy self extracting crank bolts for ease of installation and removal when it’s time to service.

Compatible with Bosch, Brose S Mag, TQ, Fazua*, Yamaha, Maxon and Specialized® Brose motor systems using the 24mm ISIS standard. They feature narrow offsets for traditional MTB Q Factor feel while offering enough clearance for motors and
chainstays.

Don’t let the light weight fool you. The Helix Race e*spec Alloy Cranks are tested to exceed E-Enduro EN17406 Class 4 standards and come equipped with custom crank boots for heavy hitting, impact resistant confidence on any terrain.

HELIX CORE E*SPEC ALLOY CRANK

E-mtb Crank Upgrade. Performance Value.
Helix Core e*spec cranks give your e-bike an upgrade with high-end integrity and aesthetics at a 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.
