Description

E*THIRTEEN Crank Helix Race e*spec | Bosch Gen4/5-Brose S Mag-TQ HPR50 | black

The proven Helix Race crank is now available as an e-bike version. The new development from e*thirteen not only impresses with its simple CNC design, but also has a lot to offer technically.
The crank arms are made from forged 6066-T6 aluminium and are then optimized using CNC machines. High rigidity and strength are achieved through forging. The CNC machining removes the last gram that is not needed to withstand even the highest loads. With the tool-free APS system for adjusting the bearing play and the P9 interface, crank assembly and disassembly is quick and easy. The durability of the robust aluminum crank is further improved by the crank boots supplied. Despite its low weight, the Helix Race e*spec meets the requirements of the E-Enduro EN17406 Class 4 standard.

APS Adjuster
Adaptive Preload System refers to the tool-free adjustment system for the e*thirteen cranks, with which the lateral bearing play can be adjusted. This system simplifies crank assembly enormously and makes assembly errors virtually impossible.

P3 Connect
The P3 Connect system was developed on the basis of the P3 Polygon Standard from 1937. The contact surface between the 30 mm oversized axle and the crank arm ensures an extremely rigid connection.
