IF IT WERE ME:
-Black cables
-Black fizik microtex soft touch
-Exustar ti carbon pedals (Just like LOOK keo's, infact they are compatible with look cleats. I have them and love them. One of the lightest pedals on the market and cheaper than carbon max)
-Black carbon cages
-Black and grey garmin 500
There is a lot of color already going on with that frame. Trying to match reds and other colors can look really tacky if not done right and generally looks overdone. Just my .02
