BLUE LUG Original crank set "RMC CRANK SET".
The combination of the slender arm and the thinned chain ring creates a classical atmosphere.
The crank arm can be 165mm or 170mm, and the chain ring can be selected from two types, single speed and multi speed.
Recommended for cross, truck, touring and commuter bikes.
Includes chain ring bolt and crank cap.
*You can also use the multi-speed crank as a single (please note that the single version cannot be used in geared).
*When using the front single (geared), we recommend using it with a chain keeper or narrow wide chainring.
