e.thirteen Helix R e*spec Specialized M30 SL1.1 Crank, Self Extractor - black

Helix Race e*spec alloy cranks offer a powerful alternative to carbon fibers for riders who prefer alloys or do not want to pay for carbon to get a premium product.

The forged and extensively CNC-machined Helix Race e*spec crank is a piece of machining art that allows you to customize your fit and dream e-bike build.

These cranks are a serious upgrade that increases strength and pedaling resistance while reducing the weight of your bike. Available in lengths preferred by e-MTB riders for more pedal clearance with low bottom bracket frame geometries. Equipped with built-in, self-extracting aluminum crank bolts for easy assembly and disassembly during maintenance.

Compatible with Specialized Brose motor systems with the 24mm ISIS standard. They feature tight offsets for the traditional MTB Q-factor feel while providing enough clearance for motors and chainstays.
