I thought I could make a 56 work, but no dice. Ridden for less than 100 miles. Fantastic condition. Not a mark on it. The frame can do wireless or mechanical. Any questions, ask away! It has a Sram Red BB30 bottom bracket in it. I have all the extra hardware and spacers that came with the integrated bar/stem. The steerer tube has not been scalped. All work was done by a professional. The wheels in the photos are not included but the integrated bar (130mm/42cm c-c) and the seatpost are included for free.
