We had the factory update our favorite carbon road frame with a little better clearance and some other small tweaks, and this is one of the first out of the new mould. Rides awesome! DTSwiss full carbon PRC 1400 aero wheels with DuraAce Freeza brake rotors that ride awesome all the time, Ultegra Di2 grouppo, carbon 42cm width bars. Schwalbe ProOne tires set up tubeless 30c front and 28c rear. JP the owner has ridden this bike a handful of times, he's 5'7 or 5'8 and it fits him perfectly. Can make any changes you want to this bike just let us know!
