I am thinking of buying a 2011 Kona PhD on sale at LBS. I would want to mount a rear rack to this bike. However, it has seat stay braze ons for mounting the top of the rack but no holes or eyelets on the rear dropouts for attaching the bottom of the rack. This seems strange and the salesman recommended purchase of a rack which clamps to the seat post. I've looked at photos of the previous models of this bike and found that the 2009 has holes in the rear dropouts. So, am I missing something obvious or do I just need to get some sort of adapter to attach the rack through the rear skewer? I don't quite follow why there are braze ons on the seat stay but no holes in the dropouts. Any advice appreciated. Thanks.
