I am 5' 1", but I think I may have shrunk a half inch.
I ride a 51 cm Kuota Kredo with a sloping top tube. I was sort of not smart about buying this bike. I feel OK on it, but I can barely stand over it. I'm fine when I come to a stop, since I'm leaning on one foot, usually. I have narrow bars (38 cm) and I just put shims in the brake levers. But, I still don't feel comfortable descending in the drops. I don't know whether it's me (just being scared) or the fit. I have been professionally fitted for this bike, computer, laser, the whole thing. I'd love to get the Poco Salsa bars, but my ergonomic carbon bars were just too much $ to get rid of, and I don't want to put aluminum bars on a carbon bike.
My last bike was a 47 cm Trek 5200 wsd. The stand over was better, but I had a lot of neck and back issues with that bike that I don't have now. I upgraded . to Dura Ace because I could never shift to the big ring. I wonder if I ever can find a bike that addresses all of my issues...
My Jamis Coda is a 44 cm hybrid and I have a "small" 15" mountain bike, that I think is a bit too big for me.
I have no problems buying clothes in petite sizes, but in the last two years, pant lengths have gone from 28 or 29, to 30, which is too long for me, unless I am wearing heels.
