Unless the frame has a _very_ long top tube or the rider uses _very_ short toeclips, there is no way these numbers compute. In my size (57-58 cm top tube), bikes with a 73 degree head angle and 40 mm fork offset (rake) usually still have toeclip overlap.
If your angle finder did not read correctly (or the bike wasn't on level ground), then perhaps your angles are off. If your rider used M size toeclips, then this could be a bike with a 73-74 degree head and 40-45 mm offset. That isn't far off a traditional racing bike geometry. It will feel great at high speed (>20 mph), but at lower speeds, it may feel twitchy to the uninitiated. My Marinoni's measurements are 74 degrees and 40 mm, if I recall correctly. A great-handling bike at racing speeds, but not much fun at 13-15 mph.
Do you happen to have a front-center measurement? That would allow double-checking the angle measurements. -- Jan Heine Editor Bicycle Quarterly 140 Lakeside Ave #C Seattle WA 98122 http://www.bikequarterly.com
