e*thirteen Helix Race e*spec Crankarms - SRAM DUB Powertrain - silver

e*spec cranks for SRAM DUB Powertrain drive units.

Helix Race e*spec Alloy Cranks offer a high-performance alternative to carbon fiber for riders who 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 ideal 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 shorter lengths for improved pedal clearance on low BB frame geometries. Equipped with built-in alloy self-extracting crank bolts for ease of installation and removal when it’s time to service.

Compatible with SRAM DUB Powertrain motor systems. 

Don’t let the lightweight fool you: Helix Race e*spec Alloy Cranks are tested to our exacting E-Enduro standards, and are suitable for EN17406 Class 5 applications.  They come equipped with custom crank boots for heavy hitting, impact-resistant confidence on any terrain.
