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. 

Read more about optimising your chainline here

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:

  1. Bolt the gauge onto your crank
  2. Rotate the crank to observe tooth clearances with the frames chain stay
  3. Identify the optimum size chainring for your setup.
  4. 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

3D Printing Specifications

  • STL 3D File 
  • 218mm x 111mm total size
  • Support material required for printing tooth overhangs
  • Recommended settings:
    • 0.4mm nozzle

works great

I printed it easily on an Ender 3 sliced using Cura. Fits perfectly.
I put some paint on the top layer and sanded off the excess so the numbers and logo can be seen easier.
It saved me from buying a chainring that would have been too big.
Excellent tool.
