You have to ask yourself if the $4,500 extra for the Specialized is worth the name badging on the frame? The sweet spot in my opinion is the CF SLX 9 Di2. It is now $6,499 and comes with Dura Ace R9200 w/power meter, top of the line DT Swiss ARC 1100 Dicut wheels w/180 hubs and a semi adjustable cockpit (bar width). That config is even better spec'd compared to the Tarmac Pro, and still $2,000 less money. The version I want, that is not available in the US (at this time) is the Ultimate CFR Di2 Aero in the Alpecin-Deceuninck Replica colorway. It's an age-old dilemma, do you want a Rolex on your wrist or an Omega? They both tell time, but one screams to your bro's "you're a Baller", even though you can't shoot or dribble for squat.
