Have you ever wondered what is the largest size chainring that will fit on your track bike?

We get asked this question a lot. The short answer is that the only way to tell is to test it out. Even two identical frames may allow for different sizes of chainrings due to the tolerance stack between components.

We developed this handy tool to do just that. Each tooth on the gauge represents a different size chainring from 49 to 70 teeth.

Bolt the gauge onto your crank
Rotate the crank to observe tooth clearances with the frames chain stay
Identify the optimum size chainring for your setup.
Chainring or bottom bracket spacers may be used to offset the chainline to increase the chainring clearance.

144 BCD
49 to 70 teeth
CNC machined from from PE plastic
Gloss black
