If saving weight is the only goal, you can do it
much cheaper. I have a couple of pairs of wheels I build using components from
bikehubstore.com that weigh 1285 grams. I used their lightest hubs with Kinlin XR-200 rims, 20 Sapim Laser spokes in the front and 24 spokes in the rear with Lasers on the left and Sapim Race spokes on the right. The fronts are laced radial and the rears are 8x16 laced radial left, 3x right. I'm 170# and they've held up fine on crappy New England roads. Oh, yeah, they cost under $250/pair to build! Even if you add $100/pair to have them built, they're still a bargain.
