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