Myself; I use a fahgettaboutit mini through the rear wheel and around the chainstay or seattube depending on the thickness of the rack I'm locking to. Then I use a separate abus cable through the front wheel and front triangle and around the rack. So far it works for me. Now, I'm not riding a Pinarello or a Venge or something, but I do ride a CAAD10 or a Giant Defy. I also live in a college town which has a fair amount of thievery. I also don't leave my bike unattended all day (It comes inside at work). I do lock it up for an hour or two on occasion while shopping or catching a movie or whatever.
