The shifting system is Dura-Ace Di2 10-speed and works perfectly. The bike is size S/M (160-175) is in perfect condition and includes a bottle cage. I have changed brake housings, brake cables, the handlebar tape is new, rubber hoods of the levers also new (although with a small notch that was made when putting them on, they don't fit 100%) and chain also completely new (unused, 0kms). It only has a small chip on the frame and scratches on the levers (photo attached). Mechanical disc brakes. It can be taken with DT Swiss wheels or the PR2 ones (these last ones are tubeless ready).
