Bianchi Aero-Lenker-Vorbau-Einheit für IMPULSO RC

I am selling my Bianchi aero cockpit (stem/handlebar unit).
According to the manufacturer it has the following dimensions:
"Reparto Corse AeroFlare Flare: 16° Drop: 120mm Reach 80mm Steerer Interface Diameter: 1 1/8" HandleBar Size: 120/440 Material: Epoxy - HM-HS Carbon Fiber Composite "
I bought the Impulso like this, but the unit was much too big for me. I rode about 400km with it. The bike didn't fall over, I didn't crash - there's no reason for me to doubt its integrity. My friendly mechanic, who carried out the change/conversion, is of the same opinion - apart from possible residue from the handlebar tape adhesive, the part is as good as new. However, I am selling privately and therefore no liability is accepted.
I will be happy to answer any questions that are not answered by the photos. I prefer to ship with DHL because of insurance and tracking.
