I'm no fit expert, but I wouldn't want it to be too close on a cross bike. I think you don't have inches of clearance, but you wouldn't want the bike to *ahem* jam into things either.
I have a cross check. I do not ride cross - I ride roads with it (love it anyway). Flatfooted, the bar just barely touches. I think it's OK. I wouldn't do more than that. (and I really do question Surly's measurements - I shouldn't be able to straddle my bike. But I can.)
