Bike Geometry Project

Had to share this one.

http://hiddenfortress.org/geometry/index.html


I had never come across this previously. Worth a local hard drive save for lots of us here. I do not recall it in any of our threads past...


Note: the WB for a 1985 Bridgestone 400 in the file is incorrect. FWIW.

Bridgestone 400

My first "good" bike was an '85 Bridgestone 400 and the other mistake in the table is that the frame sizes were specified in inches, not cm.

The 400 was available in 19", 21", 23" and 27" according to the 1985 catalog I have. Mine was a 23". That year the only bike whose frame sizes were specified in cm (actually in mm) was the top-of-the-line Grand-Velo 3100.

Mine may be an 84 ? it IS a 25" and I have a portion/page form a catalog which the rest of the figures are spot on to my frame for the 25".

The one I have goes 19,21,23,25,27.

Whoops!

Sorry for the typo. The 400 was indeed offered in 19,21,23,25 and 27" sizes. I just left out the 25. My original point is that there was no "58" as the sizes were all specified in inches.
