The 612 track crank is an extremely stiff and strong 144mm B.C.D. track crank. Itβs at home as much on the busy avenues of your city as it is on the boards of the velodrome.
We sweat the details, so the 612 (Minneapolisβ area code) is cold-forged, resulting in a tight grain structure. The upshot is that itβs strong, which means more riding and less worries for you.
It utilizes the classic JIS square taper spindle and comes with a color-matched, 46-tooth, 1/8th chainring.
