Sure, these days with the likes of Mialo, Litepro, etc. one can get a basic wheelset for a third of the cost of these. These are not about value.
These are 406, and weigh 491/657 grams sans QR.
I haven't used them. Always thought the bang for buck ratio was too low. What ERD are these? Looks like 451mm. What do the individual wheels weigh sans QRs?
