The 2012 QR CD0.1 Di2 was probably north of $7K. It looks like the cockpit is upgraded to PRO bars. I cannot tell from the pictures which PM it has. All of the components do seem age appropriate for a top-end bike.
Real Design was QR's house brand long ago, and they were designed with the help from Steve Hed. http://www.slowtwitch.com/...bikes/tribikeqr.html
$2,900 is a decent price for a decent bike with electronic shifting, a PM, and carbon race wheels. It may be a little high, but the alternative could also be nothing or new for $5,500 (Premier Tactical).
Edit for a couple more thoughts... If the bike was setup with a PM when new, there were not a lot of options back then. Judging from the picture, and that the owner may not have wanted to rebuild the wheels, it is probably not a Powertap hub. So, that leaves stuff like SRM, Power2Max, and Quarq. It does not look like an iBike PM. It looks like there is a massive head unit on the extensions, so maybe that is the dedicated PM head.
