All-City Pursuit Special
$79.99
The Pursuit Special is All-City's addition to the pantheon of high end track chainrings.

These beauties are cnc’d in the USA and utilize a proprietary tooth profile for smooth and quiet operation. The 49-52’s utilize a solid body design with reliefs in the back for weight savings, while the 46-48’s have full cutouts. In sticking with the theme of their aluminum track bike, the Thunderdome, All-City named these rings after Mad Max’s car, the Pursuit Special. - Material: 7000 Series Aluminum - Ring Position/Type: Single
All-City 612 Track Crank
$140.00
The 612 Track Crank is an extremely stiff and strong 144mm BCD track crank. It’s at home as much on the busy avenues of your city as it is on the boards of the velodrome. All-City sweats the details, so the 612 (Minneapolis’ area code) is cold-forged, resulting in a tight grain structure. The upshot is that it’s 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.  - Recommended Spindle Length: 110mm - Spindle Interface Type: square taper JIS - Bolt Pattern: 5-bolt - BCD: 144mm - Chain Compatibility: 1/2-inch x 1/8-inch - Weight: 726g w/ ring and bolts - Bottom bracket and retaining bolts not included
