Congrats on the awesome and beautiful build. I like the red accents but I already did that for my Helix OS - SRAM Red, Chris King Red Inset headset, Fizik Alliante Red braided carbon rails, wheels with Red DT-Swiss prolock hex nipples, and am only missing a red seat collar. Would you consider a red seat collar?
I got the R330 with the black Cane Creek 110 headset - so I decided to use black accents this time. I have an appointment for a bike fit tomorrow to determine a geometry for 4 hour+ rides for a comfortable stem length, steerer tube spacer height, handle bar drop and reach, seat post height and offset, saddle angle, and pedal cleat position and angle.
I will probably order an ENVE stem to match the ENVE fork. Apart from that, hmm...
