e*thirteen Helix Race cranks, 1x12, without chainring
E-13 Helix Race cranks
e*thirteen loves aluminum! Because we knew lightness, confidence-inspiring power, and stunning looks were top priorities for our riders, we went for all three at once.
Helix Race are top aluminum cranks with XC weight and strength of enduro cranks, worthy of EWS. Forged AL6066-T6 arms were designed to maximize stiffness and strength while minimizing excess material. CNC intervention can be seen on almost every part of the crank, creating a charming aesthetic and weight savings. A forged AL7050-T7 axle with a diameter of 30 mm provides increased stiffness and further reduces overall weight. e*thirteen's P3 spindle interface and updated self-tapping screw system promise easy servicing.
Helix Race cranksets are compatible with the Boost and SuperBoost chainlines via the versatile Helix Race shifters, which come in the full range of Helix colors to match Helix cassettes and other e*thirteen components.
