I am looking for advice on a lightweight wheelset that is disc compatible for road use. I have Shimano disks with centerlock rotors on my current stock wheels. I would like something as lightweight as possible and good for climbing. So, maybe I'm something of a weight weenie. Also, I'm a small guy at 130lbs and ride on pretty decent roads. I'm fine with building up a custom wheelset and I'm willing to spend up to $1500. Also, I would prefer a rim without a brake track, though that is not a requirement. Suggestions?
