Nick asks about handlebar sizing:
It is my understanding--I think it came from the old Coni book--that handlebars should be the same width as the shoulders--to the point of the bone when squared.
Bars are often too wide. I have pretty broad shoulders for a woman, but I cannot tell you how much the quality of my life improved after I found some 38cm center-to- center Cinelli Mod. 66 bars to replace the 42's I was riding. the same holds or custom fitting I have done.
I prefer a deep, well-rounded drop, and I suspect that drop and curve are more taste and riding style than formulaic. Therefore, width is definitely--in my opinon and experience--more important.
Hope this helps, Jackie "just bought some 38cm Mod. 66's on Ebay for a song!" O'Sullivan
