The Kosei K1's are extremely light, about 17~ if I remember right, but they are not the strongest wheels. They're designed for racing, so don't go around hitting huge potholes all day long. I'm not sure how strong any wheels under 250 will be, though. I think they're ~200/apiece. They definitely have the racing look... so if you're going for that I think they're perfect. I love the look of no center cap.
