I have a bike fit question for the pros out there. I’m looking for a road bike for my wife who is getting started in cycling this spring. She’s 5’9" tall with an inseam of 81cm. I have found a used Bianchi 55 cm (center to top) road bike that has a 55 cm top tube and I’m worried that the frame size might be a bit too big for her. The next size down on this frame size is 53 cm with a top tube of 53.5 cm, which seems a bit too small. Any comments on which frame size would best fit her. Based on her measurments it looks like the frame geometry of these 2 sizes may not fit her.

Hi Reparto Corse, is your wife’s name Celeste?
Why don’t you get the shop your buying the bike from fit your wife? Any shop I know would include that in the price, and a half-decent fit in person will be much better than an expert online fit.
AAAAARGHal bargal!!! CELESTE = YUCK!! Bleck! How could you even use the word in public? :), As in Celeste Green, possibly the only color that USAT should outlaw on a bike, except perhaps for gray. :),

It may just fit perfect… I had a Bianchi XL something… size 55. Great bike, until I broke the frame However, I am 5’11.75 and fit close to perfect on it as a tri bike with retrofitted seatpost etc… I used a 110mm stem and a Thompson seatpost. I do however like my bikes as small as possible, and this one was a little too small for regular road riding. If you slide the seatpost forward, you know the virtual tt length shortens and you end up with a “different” size.
If you can,try it in the store. Good luck.
Hey, now! It’s a love / hate thing…I wouldn’t ride anything else but Celeste.
All in jest, of course. But, I am amazed that anyone likes Celeste Green…
