Looking for an "OFFICIAL" ProFlex Sizing Chart

[cincirider]

Hey gang, I'm trying to sell my MEDIUM ProFlex 657 to a guy here in town.
He's 6'-0" and is worried a MEDIUM is too small!
Is their a "OFFICIAL" SIZING chart that list Frame Size to Rider Heights???

I think my 855 is a Medium, and I'm 6'3" with a long inseam (35"). I do use a very long seatpost though. The main difference as I understand it is the top tube effective length as I think M/L both have approx 20" seat tube.

could be right here ed..i know the way big 756 is longer in the top tube by only 1/2 inch than L.

is the closest that i know of,scroll right to the bottm of the table look at the 1000,2000,or 3000.Those frames represent the x57 frames.however the 657 was actually an x56 frame.I would think that most dimensions are very similar
