e*thirteen Helix R cranks

e*thirteen cranks are designed for tough enduro use, but their weight is comparable to XC models. The crank body is made of forged 6066-T6 aluminum, then CNC machined for maximum rigidity and removal of excess material. The 30mm diameter 7075-T7 aluminum axles ensure an extremely strong and rigid connection between the arms.

The APS (Adaptive Preload System) allows for simple, tool-free adjustment of bearing preload and makes installation significantly easier. The connection is provided by the P3 Connect interface, which provides maximum rigidity and reliability.

Mounting the chainring is quick and the tool needed to secure it is included in the package (compatible with Hollowtech II wrench, 36mm open-end wrench or pliers). The package also includes plastic protective arm sleeves that increase the durability of the cranks.
