[Bump]
I've recently inherited a frame, and I'm wondering if you wouldn't mind sharing with me your thoughts as to whether if my conclusion that the geometry is close enough to what was suggested in this thread.
The new frame I found has the following geometry center-to-center:
top tube: 21.5 inches, or 54.6 cm
seat tube: 20 inches, or 50.8 cm
bottom tube: 24 inches, or 61 cm
head tube (tip to tip): 3.5 inches, or 8.9 cm
The suggestion in this thread so far was to find a top tube with length of 53.4 cm and seat tube of 52. I figure if I play a bit with the stem, bar (perhaps a moustache bar), and seat post length, I can make this new frame work. I'm thinking of converting this new frame into a fixie/townie/commuter (max 15-mile ride), so perhaps the frame doesn't have to be at very dialed-in fit.
What do you think? Thanks very much!
