Going back to the late 80's I was accustomed to frames obviously being sized based on the seat tube and the measurements were either:
- Center to Center: center of BB to center of seat & top tube juncture
or
- Center to Top: center of BB to top of top tube

Reason for asking; I'm looking to replace my ~ 92 Cannondale 2.8 frame
Current size is a 56 and measures 56cm from center of BB to top of top tube and then 59cm to the top seat tube / collar.
The top tube is also ~ 56cm from center to center (seat / top - seat / head)

I'm looking at an FSC on Ebay; basic search seams that most are reasonably pleased with them.
Looking at what they are calling a size 57 which says the seat tube is 57 bb-top but a top tube of 544.9mm or (54.5cm).
The FSC frame seems to have a slightly sloping top tube but the top tube still seams relatively short.

Anyone familiar with the geometry of this FSC frame?

Don't want to be too cramped. I know I can adjust some with a longer stem but afraid of going to long and making the squirly (sp?).

I'm 5'-11" w/ a 32" inseam.

Thoughts on sizing?
This frame?

Seems frame sizing is not as consistent now based upon reading posts and e-bay adds.
Obviously some ebay folks are unaware.

Thanks,
