A viner professional was made with columbus SL and equipped with nuovo record - there were two people who raced viners around here in the 1980's. This looks to be a late 70's or early 80's one. The word 'Special' meant one-off custom at one time in Italy (or top of the line), but it kinda got watered down by the end of the 70's. It looks to be in beautiful shape - you should think about getting the decals cleared, because I don't think that this bike had a top coat, and the decals will be fragile. 111 will work but might be a little wide. Be sure and get a 70 mm one, because of the italian bottom bracket. Post us some piktoors when you get it going.
