if you google 'robert gesink giant propel' go to his twitter feed and you can see his current training setup. Not clip on, but TT style bars.The original stories around the launch mentioned clip on aero bars and a mount for the Garmin Edge, as non of the standard after market stuff fits onto the Contact SLR Aero handlebars. I haven't seen any mention of these since, my LBS doesn't know about them, and I can't find anything on the Giant site.
Does anyone know anything about these? Price, when they're being released... do they exist?
