I have no clue how to use this site but have a question. My big block is a 56, even at 5'11" its too big for me. There is a 54 mark v on offerup I'm looking at buying so I've been reading all these forums trying to figure out how I'm gonna fit on this frame. Until I figure this thread forum thing out I was hoping you could forward this to somebody who may know..? Thanks dude
