E*THIRTEEN Crank Helix Core e*spec | Bosch Gen4-Brose S Mag-TQ HPR50 | black
The Helix Core offers all the features of the Helix Race at a very fair price. The crank arms are made of forged 6066-T6 aluminum. High rigidity and strength are achieved through forging. 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.
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.
Note: The chainring shown is not included in the scope of delivery.
