Thank you all for your responses. I really appreciate it. My friend, the seller, has not put any miles on the front wheel, so it is virtually brand new. What happened is that he bought a front and rear 404. Before he even mounted the front wheel he decided that he wanted a Zipp FC 303 on the front and keep the 404 on the back. I have a rear Zipp 404 FC CC wheel right now sitting in a wheel bag. This would complete the set.
