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:
- 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

Was truly a perfect coincidence that my friend got a 3-D printer, while myself and a friend needed to check chainring clearance (before ordering from Velobike). Within 2 hrs the tool was put to use, confirmed clearance with no fuss. Truly appreciate that I didn't have to ship such a simple tool halfway across the world
Thank you for your comment! We are happy to hear that our Chainring Clearance Gauge was able to assist you and your friend with checking your chainring clearance without needing to ship the part around the world. Thank you for choosing our product and for your support!
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.
