BLUE LUG original crankset "RMC CRANK SET".
The combination of a slender arm and a lightened chain ring creates a classical atmosphere.
You can choose from two types of crank arms, 165 mm or 170 mm, and chain rings, one for single speed and one for multi speed.
Recommended for bikes such as crosses, trucks, touring and commuter.
Includes chain ring bolt and crank cap.
* You can also use the multi-speed crank as a single (please note that the single can not be used in geared).
* When using with a front single (geared), it is recommended to use it together with a chain keeper or narrow wide chain ring.
