65, great essay, and two questions (at least!):
What is that bell, where did you get it, and do they have more?
Can you describe the more aggressive geometry, as you see it?
Your comment is very interesting, because of my two UO-8 frames. I have two frames, both 1970-1975, both 55 cm c-c, and with the same braze-ons and the angles/CS/ST/TT lengths. Where they differ is offset, by at least 1 cm. My green one has 70 mm, and the blue one has 55-60 mm. BF'ers OFG, redxj, and redneckwes all had something to do with these bikes. I've been riding the green one, but not yet built the blue one, so I can't really compare them on the road.
