Shimano FC-CX50 Crankset

The Shimano FC-CX50 crankset - With Cyclocross-specific gradation

With the FC-CX50, Shimano has introduced a 10-speed crankset especially for cyclocross use. It impresses with smooth shifting, no grinding and a cyclo-cross-typical gradation of 36-46 teeth (110 mm bolt circle diameter). The 5-arm aluminium crank also features 2-Piece Design, in which the integration of crank arm and bottom bracket ensures special stiffness with the lowest possible weight.

Technology:

2-Piece Crankset
With the 2-piece designed cranks from Shimano, the right crank arm is precisely matched to the interaction with the bottom bracket. This increases the stiffness and keeps the weight low. Further spaced bearings also improve strength and contribute to more pedalling efficiency. The precision manufacturing of the bearings ensures easy installation and low maintenance. 2-Piece cranks share a 24mm axle diameter with Hollowtech II cranks, so they are also compatible with Hollowtech II bottom brackets.
