I have friend who is 6'1" tall, and pants size inseam is 32". He has a Fuji road bike that is purported to be a 56cm frame, but it really seems way too small for him.

So I'm curious - what size frames do your 6'1" tall significant others ride? He wants to go the Craig's List route to find a new bike and I want to get him looking at a better size but don't know how far to go with this. We just need a better starting point.

Yeah, he SHOULD go to the local bike shop and try a few bikes out for size but that just isn't gonna happen. It's too easy that way. (Frankly I'm not really convinced he wants a bike at all but I'm humoring him for now.)
