How does Cannondale measure their frames?
Do they measure from the top, middle, or bottom or the BB? Then where to?

I have a 1987 R500(63cm). It measures 66cm from center of BB to top of seat tube.
From top of BB to top of seat tube is 63cm... if that means anything

So what is the measurement on your bike?
Here is the 87 catalog. The frame sizes are broken down here if you scroll down.

they measure by how many beer cans they need to stack up to make the seat tube

The serial number contains the size of the frame as well so if you have a frame already see what the size is supposed to be and then see which measurement corresponds with that.

Drummerboy1975, My '89 crit bike is a 56 cm frame and measures 56 cm from the center of the BB spindle to the top of the top tube.

PS My bike is pretty much spot on using the 1990 Cannondale catalog.

I have a 1987 SR500 which is marked 58CM in the serial number, and measures the same way yours does, From top of the BB to top of the seat tube, including the extension is 58MM.
