I am selling a Bianchi OLTRE PRO Di2 purchased in August 2025 and ridden for one season. The bike has been meticulously maintained and is flawless, with no scratches or damage of any kind. At the buyer's request, a new chain and new tires will be installed before the sale. A new chain and new Pirelli P ZERO RACE TLR SL tires are included in the sale, but the existing ones can be kept and replaced in the spring. The brake pads still have 1.9mm remaining. If desired, I can also replace the front chainrings with 50-34 if someone prefers easier gearing. The bike has a 4iiii power meter but is otherwise completely original and in perfect working order. The bike size is 55. I am selling it because I bought the same bike in size 53. The bike has a full Ultegra Di2 groupset.
