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.
