Shimano CUES FC-U6040-2 Crankset – Hollowtech II | 9/10-speed 170mm 46-32T

Shimano CUES FC-U6040-2 crankset

With its durable yet lightweight construction and an excellent chain retention, the 2-speed version of the FC-U6040 crank from the Shimano CUES series ensures reliable performance and efficient pedaling – both on extensive road bike tours and long gravel adventures. The HollowTech II production method not only reduces the weight of the crank arms, but also increases their stiffness, which results in maximum power transmission.

HOLLOWTECH II | The guiding principle of Shimano’s Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission. An exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve an optimum relationship between stiffness and low weight.
