cad overlay bike geometry
August 19th, 2012
I photographed each bike to compare seat and handlebar positions. For fun, I took it a bit further and traced frame center lines.
Note/Disclaimer: the fork rake and trail measurements are not reliable as I did notice some minor distortion. Actually, I doubt any measurement is all that perfect.
I am surprised to find the Panasonic has the steepest seat tube, and the trail is higher than I imagined. Also the Panasonic feels it needs more seat setback; this exercise helped to illustrate that.
The rSogn is very close to spec (aside from fork rake). Not shown is the 65 mm bb drop, which is spot on when measured in AutoCAD.
