If you're going to spend that kind of $$, DO NOT buy a bike that doesn't fit perfectly.

You said you were 5'5... I'm 5'7", have a 32" inseam and I'm on a men's 52cm frame. I would say stay away from that 54cm unless you are WAY more long legged than me.

Don't let your impatience/excitement push you into a snap decision...

I know; easier said than done.
