This bike could literally win Kona Ironman. It's that fast. It has been used but is in excellent working condition. It has not been crashed, so the paint is immaculate. Di2 functions perfectly, with shifting controls both on the base bar and on the aero bars. Cranks are the dual sided Pioneer Dura Ace with a Pioneer head unit to go along with it.
