The Diverge does have rack mounts on both their carbon and alum versions. I waffled a little bit on which way I would go, but ultimately went with the alum version, as the dealer was confident that the carbon would handle our typical load of 20 pounds loaded on racks, but I figured why worry about that kind of failure, so went with alum. It will likely be a month or so before I do any touring on it.
It's a nice ride. I love the future shock on my Roubaix, but am equally ok without FS on my Diverge.
