Just use a 12" ruler and measure over 11". The extra 0.005 inches (0.05%) isn't perceptible or significant.

I could have just replaced the ring, but decided to replace the 105 BB & Crank with new Ultegra BB & Crankset.




your chainring doesn't look particularly worn to me,

but the FD could be several mm lower for good shifting.
