Frame size question
I've got a question about frame size. I have a very nice Marinoni that I want to convert to my first fixed gear. The only problem is I think it's kind of big for me as the seat is no more than an inch above the handlebars and probably closer to a half inch. Is the frame simply too big for me and does it really matter anyway? What are the actual disadvantages to having a frame that's a bit too large for you anyway?
I'm 5'11 and I think the frame is a 56, which should be fine but I've got really short legs and a long torso. The frame feels great to me, but it's the only road bike I've ever been on and really don't know how it's supposed to feel, or if my performance is suffering because of it.
Thanks for the help guys.
