Removed from what we believe is a vintage Colnago lugged steel mountain bike that had a full Campagnolo groupset. Crankset was attached to a Shimano square taper bottom bracket (appears original Campy one was replaced) Shows signs of wear but overall as collectors items go, it is still clearly a Campagnolo product and retained the very flashy center dust covers. 42-30-20 110 BCD Please review photos and ask questions Sold as is, no returns but with free shipping.
