For some reason I'm thinking I'd like to go with the smaller size, for no real scientific reason. Bye the way, I'm approx. 5'8" with a 30 5/8" cycling inseam and average proportions. The head/seat tube angles on the Fuji are 73.5/73, respectively. The 53 Bott. is 72/74 and the 55 is 72.5/73.5. I'm not quite sure how those numbers would actually translate in regard to fit. The only pesonal comparison I can make is that I test rode a Cannondale Systemsix, size 52 (53.5 top tube), with a stock stem (probably 100 mm ?), and when in the drops, out of the saddle, it felt like my wrists were going to snap off... too short. Sorry for the long-windage, but I'm contemplating the group buy and I'd like to get it right the 1st time.
