So, in looking at the seat angle\u2026 Looks like it's being measured as the difference between perpendicular to the seat tube and parallel to the top tube. I see anywhere from 15 to 20. This can't be what that number

refers to, because it would indicate angles running from 75 to 70 degrees, a huge difference!

Anyone know what eat angle he really used on these (Merckx frames)?
