Shimano CUES FC-U4000-1 Square Crankset w/ Chain Guard

Shimano CUES FC-U4000-1 - Square crank with one chainring and chain guard for city, touring and MTB

The CUES square crankset FC-U4000-1, here in the version with a chain guard, was designed by Shimano for Linkglide drivetrains on city, touring and mountain bikes. It is suitable for 1x9-speed, 1x10-speed and 1x11-speed gears. The special tooth profile of the chainring efficiently guides the chain even in rougher terrain and prevents it from jumping off. The size of the chainring is chosen so that it can be pedalled harmoniously and comfortably on different types of terrain. This results in a chainline of 50 mm, which is why frame over locknut dimensions of up to 142 mm are compatible. The Q-factor is 178 mm. The crank is made of aluminium and steel. The four-arm steel chainring is firmly riveted to the spider. Thanks to the chain guard, your pants won't get caught between the chainring and the chain while riding.
