2010 Zipp 303 cross wheels (24 spoke front/24 spoke rear), with brass nipples, shimano/sram freehub body. Glued on are a set of Challenge Grifo XS 32mm tires. I used these twice in races. The wheel/tire set look and feel as new. No marks anywhere. I enjoyed CX, but the ole' lady said the race wheels have to go. $1400 shipped for the set.
