Ok, I'm starting to build a light weight bike from scratch. At first, I wasn't too weight weenish about parts, but when I realized I could get the weight down to below 13 pounds for an aluminum frame, I knew I had a new mission. Right now calculations are 12.86 pounds(assuming manufacturers are true to their claimed weights(Yeah right!)) without cables. I'll save a little weight after I cut down chain and steerer down.
Right now the front wheel I was going to use weighs 670 grams. I'm thinking about using the Alchemy Elf front hub, Kinlin XR-19W rim, and possibly Sapim Aero Bladed CX-Super spokes(not going to be racing with these so a little flex isn't a problem). I'm 150 pounds and wondering what spoke count to go with on front wheel. Also suggestions on spoke count on rear wheel with Sapim CS-Rays and Alchemy Orc-UL rear hub with Kinlin XR-19W rim. Any other suggestions?

    I would ask this question on Weight Weenies. Lots of knowledge about wheelbuilding with light stuff there.

    My Dura-Ace 9000 front wheel weighs 599 grams, 1350 grams for the pair. Not sure how much the Alchemy hubs cost but the bearings will likely last 2 minutes, and if you add up the cost of the wheel build you might not be far off the price of something like DA wheels that have the best hubs (unless you're on campag!) or even a Stans wheelset that are even lighter.

    20 front and 28 rear should suffice and make you happy

    I have a set of Dura Ace on one of my bikes, but to get comfortably below 13 pounds, I really need to save about 200 grams on the wheels(front and rear). No offense to the weight weenies forum, but sometimes it seems some of them are more concerned about reducing weight than the quality of the product.

    The Kinlin is a mediocre and not very lightweight rim for such a build - there are plenty of lighter, stonger and more aero rims out there. Likewise, Alchemy hub is overkill - AM Classic micro hub is just as light and a fraction of the cost.
    Make mine an Italian, with Campagnolo on the side..

    The Kinlin XR-19W is 410 grams and XR-200 is 383 grams. What clincher rims would be lighter than these. I know aerodynamics isn't Kinlin's strong suit.

    I weighed Velocity Aerohead at 415 and they are excellent

    Stans Alpha 340 with a light 80g hub in 24H form and Laser spokes/alloy nipples would be 585g. That's what I would do.

    Even the Kinlin XR200 in 28H form (all that is available in the U.K) unfortnatley with a novatec A291 hub laser spokes and alloy nipples is 600g or a bit lighter is you are lucky with the weight of the rim. Also it is cheap.

    The Alchemey ELF and ORC hubs look excellent on paper and I really want to use them.
