Wow, I am glad someone else found this because as a new cycling convert I was wondering how I was ever going to fit into a bike with measurements that this website gave me. I am riding a 53 CM bike now with a 53 CM top tube and this is what the website gave me back, no way I could ever fit into a bike with a 56-58 cm top tube. I am 5'8" tall. This has got me so screwed up, I have no idea what size bike I really need.
