Built in collaboration with professional World Cup DH and Enduro athletes, this high-performance crank is crafted to withstand the rigors of aggressive mountain biking while offering exceptional power transfer and reliability.

Materials & Engineering:

Constructed from forged AL-6066-T6 aluminum and CNC-machined for a flawless finish, the Helix Race GR crankset delivers unparalleled strength-to-weight ratio comparable to carbon.

The low-profile, CNC-sculpted arms integrate seamlessly with modern mountain bike frames for a sleek, aggressive look.

Featuring a 160mm crank arm length and a 73mm bottom bracket shell compatibility, the Helix Race GR delivers a balanced pedal stance for technical riding and optimal leverage. This crankset supports 11- and 12-speed drivetrains, with direct-mount ethirteen chainring compatibility (chains sold separately), and a 55mm chainline designed for Boost hubs (141/148). Included components such as molded crank boots, protective polymer decals, APS adjuster, and self-extractor system enhance durability and ease of maintenance, making this crankset a reliable choice for aggressive riders.

Style & Use Case:

Sporting a sleek black finish with an attractive CNC machined surface, the Helix Race GR crankset combines rugged performance with an eye-catching aesthetic. Its robust construction and modern design make it perfect for downhill racers, enduro riders, and freeride enthusiasts seeking maximum confidence and control on aggressive terrain. Whether navigating technical descents or big bike park laps, these cranks provide a solid under-foot feel with lightweight characteristics, all while resisting impacts and debris.
