I just gotna Steamroller frame a couple of weeks ago but have yet to put it together. I think it's the largest or close to it, maybe it's a 61 or 62. I'm 6'2", so I figured it would be a perfecr size. My current rig, an 04' Pista, is a 61cm frame, and it fits me perfectly. I think you should go with a 59cm frame, but that's just my opinion. Roll with it, baby.......
