i'm really interested in this model but I was wondering what other parts are going to have carbon? will the seatpost, stem, handle bars, fork have carbon too? and whats the main difference from the ultegra sl compared to the dura ace only the drive drain? man I can't wait to preorder one of these.

Both will have full groupo kits... matched shifters, derailleurs, cranks, brakes cassettes and chains... all Dura-Ace on the Spectre Ace and all Ultegra SL on the Spectre SL. They may also have matched Shimano wheelsets, though that has not been finalized yet. The common parts shared by both models will be frame and fork as well as a few peripheral items like tires, saddles, handlebar tape and perhaps pedals. Otherwise, the Dura-Ace model will be upgraded in all major components... drivetrain, brakes, wheelset. It will also likely have an upgraded cockpit set. Early specs indicate Ritchey Pro Carbon on the SL and Ritchey WCS Carbon on the Ace.
