I'm looking at buying an older 650c frame and he offered these wheels with it for an extra $200. I have a 650c tri bike that I'd love to use them on and $200 seems like a good deal to me but I don't know anything about them. He said they were from the late 90's or early 2000's. Could someone identify them for me and tell me if they're worth looking at. I don't want to be a rolling carbon death wheel

Turns out they are 500 but I can't figure out the hubs. I guess I might be able to figure it out when I look at them tonight.

They look in good condition, $200 is a very good price. Heck, If you don't buy them let me know, I'd be interested if you don't want them.

My wife uses old Zipp 400 and they are still going strong.

I did end up getting them. I feel like i stole from the guy. I got an older b2 felt 650c frame, profile design carbon x aerobars, and those zipps. I paid $300 for it all. I'm quite happy with the deal.

Wow! that is an amazing deal. Enjoy the new equipment.

I will, now I just have to start workout so I can justify the purchase.
