We sweat the details, so the 612 (612 is Minneapolis’ area code) is cold forged instead of melt forged, allowing for a better grain structure in the metal and producing a stronger and more durable part. It utilizes the classic JIS square taper spindle and comes with a color matched 46 tooth 1/8th chainring. Use it on the street, use it on the boards. Whatever you throw at it, the 612 Track Crank can handle."
