I have not heard about these wheels, but the rims look like they are semi aero and more than 18 cm deep. I did not see a weight on the wheels. they look like pretty fast wheels for the flat lands, but I'm not sure how good the bearings are and how light the wheels are. with low spoke count, the rim need to be pretty strong and at that price, I just can't image how good the bearings can be. take a wheel with dura ace or record...spin it and watch it spin, and spin, and spin. a good hub with smooth bearings will make a fast bike feel fast and rough bearings will a good bike feel slow.
