The disc is probably about 4 years old, but I only raced with it for 1.5 seasons for triathlons, so call it 15 races. Mileage is approximately 400. It's in great condition and is a great race wheel. I just don't race anymore and decided to sell it.
You'd probably have to re-glue the tire, but it is low mileage and a great tire - a 22mm conti sprinter. The spindle is Shimano compatible (and if you need a cassette to go along with it, I have many combos).
Sorry - I paid quite a bit more than that (especially with the tire and cassette) and it really hasn't been used much. They're going for between $300 and $400 without tire or cassette on ebay. I'll sell it for $350 (including shipping). Still a great deal for you. Let me know
