All-City 612 Track Ring

This chainring uses a standard 144mm bolt circle diameter (BCD). You must ensure your crankset is also 144mm BCD, which is the industry standard for most track-specific cranks.

No, this chainring is designed specifically for 1/8-inch chains, which are standard for track and fixed-gear drivetrains. It will not work with the narrower 3/32-inch chains typically found on geared road bikes.

While it is built to handle the demands of track racing, it is perfectly suitable for street riding. Its durable construction makes it a reliable choice for fixed-gear commuters and city riders.

The gear ratio depends on both the chainring and your rear cog size. A 47-tooth ring is a common size that offers a versatile balance for both acceleration and maintaining speed, but you should calculate your gear inches based on your specific rear cog to see how it compares to your current setup.

No, the chainring does not include mounting bolts. You will need to reuse your existing chainring bolts or purchase a new set that matches your crankset.
