I have the Campy Zondas, which I think are a very reasonable wheelset for training and racing. Overall very similar to the Eurus but cheaper by a few hundred $$$; abit heavier (but still around the 1600g mark, which is fine for my 150 lb carcass). I think they use a steel free hub (vs. the Eurus, which uses an aluminum free hub, I think). Spin up and roll well. Very durable for the cracked asphalt, chipseal, and potholes of SW Houston. My only qualm is that you can't lace a PT to these rims, as they use the G3 lacing system.
