The 612 Track Crank (six-one-two) is an extremely stiff and strong 144BCD track crank. It is at home on the busy avenues of your city as it is on the boards of the velodrome.  It is a hardworking crank that you can ride the heck out of without worry. Day in day out, on the job or just for fun, the 612 will get you there.

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.

We’ve been working intensely on cross product and the JYD lately, so I was beyond stoked when All-City Global Product Manager Amy “The Hammer” Kippley gave me a track chainring to design. Images of track bags full of All-City chainrings danced in my head.
