The elegant Shimano FC-RS520 crankset at the level of the 105 R7100 series offers excellent value for money and is also compatible with 2×12-speed components of the Dura Ace and Ultegra groups. The two-piece design with an integrated aluminum crank arm makes the crank not only very light, but also resistant. With its 4-arm construction, it is particularly suitable for modern road bike frames designed for disc brakes.
Also compatible with frames that feature a rear installation width of 135 mm and a chainstay length of 410 mm.
