I am considering having a set of custom wheels made up. I would like them to be lighter and more aero than my current Ultegra/OP’s. I want to use readily available parts like DT spokes and Dura-Ace hubs. I like the OC feature of the Velocity Arrowhead rims. I weigh 150 lbs. Has anyone built a set like this and what would they weigh. Could I get a set like this to weigh close to 1500g? Who would be a good wheel builder who uses Shimano hubs (not Speedcific?) and Velocity rims?
