I built these up about 2 months ago and have ridden them about 1000km. They were my pride and joy wheelset - such a pleasure to ride - very comfortable and VERY fast. They are Campagnolo 10/11 speed compatible only. 32-spokes rear and 28 spokes front.
I'm selling as I over-extended myself on the bike-spending front! They come with 13-26 Centaur 10-speed cassette, but can remove if you don't want it. I have the matching chain if you do.
Complete wheelset price is £500 including UK delivery. If you just want the hubs or the rims, I can do the hubs for £350 or rims for £150. The Vittoria Open Corsa SC tyres are pretty well used, but if you're just using them for racing probably have enough tread for a few sessions. Spokes are Sapim Race with DT pro-lock nipples. They are dead true and running very smoothly.
Note there are a few marks on the lips of the rims from tyre lever harassment... but they're just cosmetic - no damage to the rim - see pics.
New, these wheels cost around £800-£850 or around £900 with the tyres, so at £500 2nd hand, you're getting a bargain.
