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?

Think I'd go 20f, 28r with those. And use heavier DS spokes.

I'm amazed that you are getting that light with an aluminum frame... not normal unless you are spending a lot on parts.

It is a Pro-Lite Bella frame that weighs 1165 grams. Drive train will be 2013 SRAM Red. Let's just say the Germans will have a little extra cash in their pocket with most of the other components minus the fork(Enve 1.0) and brakes(TRP R970 SL).
