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.
Note: This is a digital download for 3D Printing only.
How to measure:
- 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.
Specifications:
- 144 BCD
- 49 to 70 teeth
- Note: this is a sizing tool only, it is not designed to interface with a chain

Works as advertised. Printed in no time and takes the guesswork out.
This is such a great tool without breaking the bank. Really easy to set up on my printer and without that much time have the gauge ready to go. I was always worried about my frames tolerance for different chainring sizes. Saves me time and money for my future purchase of a chainring.
Download, print, check it couldn’t have been easier to see what chainring fitted my bike.
Before this it's hard to know what's the limit of chainring on frame. Usually have to buy or borrow chainring to know can or cannot fit with the frame which cost a lot of time, but with this gauge, it save a lot of time and cost. You guys rock!
