When I raced (over ten years ago now) Cosmics were a popular wheel set. They had a sound all of their own. There's a lot of competition out there for wheels so I've no idea where they stand in the pecking order now. However, they're a low spoke count so wouldn't suit me since I've put on a bit of weight otherwise I might have considered making an offer. Disk brakes are also now the 'go to' type of wheel so rim brakes can be difficult to sell on. Good luck though 👍
