I hope somebody will kindly answer this question for me.

Are the numbers in "Allez 52", or "Reno 53", or "Via Nirone 55" centimeters and if so, what is being measured?

These numbers do not seem to correspond to any of the geometry measurements.

My guess is that they're chainring teeth. I guess I should be "BlazingPedals58."

Maybe it's a stupid question, but I decided I didn't think these numbers were arbitrary and I don't know what they are a measure of. I thought that my old MTB was called a 19" because it had a 19" seat tube. I measured it and it was 19" from centre of the BB to top of the seat tube, which makes sense, but the geometry on these road bikes doesn't seem to relate to the size numbers they are given. Just curious.
