E*THIRTEEN Helix Core e*spec Crankset | Bosch CX Gen4-Brose S Mag-TQ HPR50 | Black
The Helix Core is for anyone looking for a rugged and affordably priced e-MTB crankset. The crank arms are made of forged 6066-T6 aluminum. The forging process ensures high stiffness and strength. With the tool-free APS system for adjusting bearing play and the P9 interface, installing and removing the crankset is quick and easy. The durability of the robust aluminum crankset is further enhanced by the included crank boots.
APS Adjuster
Adaptive Preload System refers to the tool-free adjustment system for e*thirteen cranks, which allows you to adjust the lateral bearing play. This system greatly simplifies crank installation and makes installation errors virtually impossible.
P3 Connect
The P3 Connect system was developed based on the 1937 P3 Polygon Standard. The contact surface between the 30 mm oversized axle and the crank arm ensures an extremely rigid connection.
Note: Please check chainring compatibility.
