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 tollerance 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.

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
  • Gen3 tooth profile (matches our chainrings and sprockets)
  • CNC machined from from PE plastic
  • Gloss black 
  • Note: this is a sizing tool only, it is not designed to interface with a chain

Easiest way to answer your question.

What an ingenious way to quickly find out if your frame can accommodate pushing that big gear that you worked in the gym for all off-season!

great tool

For cyclists who want to use their largest chainring, this ruler is a must-have.

As the number of teeth on the chainring increases,
Even if you know how far the radius will stretch
It is difficult to accurately measure the space to the chainstay,
This ruler makes it easy.

Also, the existence of this ruler itself speaks to the high precision of the Velobike gears.

sorry if the translation is wrong

Very handy tool.

How big a chainring can you fit on your track bike? Big chainrings are not cheap but this tool is and will let you know exactly how big you can go before it fouls the chain stay. It is a brilliant idea and quite frankly way better quality than it needed to be but typical of Velobike to produce a high end product.
