I bumped into this when I was checking the specs on the Bonktown deal for the Reynolds DV3KT for $1k. (not as good a deal IMO as another Reynolds wheelset BTown once offered made w/DT Swiss hubs also for $1k)
Anyway saw this: Sub 900g wheelset - Reynold's RZR 46. LOTS of carbon including the hub and spokes.
More than $4K?
