You could always do what I did and buy Chris King ISO hubs, arguably the best hubs in existence, and then use DT competition spokes to lace then to your favourite rims. I'd go Mavic 521's for light weight or Mavic 721's for a bit more strength. This way you have a set of hubs that will outlast mankind and can easily replace rims and spokes as they get damaged instead of relying on often difficult to get proprietary parts or replacing an entire wheel.
the new EDGE DH carbon rims 32mm, 400grams i think....if steve peat can ride it...so can u !
and then build it with CHRIS KINGS...and Ti spokes !!! ...that will be the lightest...strongest wheels ......
u might think TI spokes are weak.....but i had Ti spokes on m DH wheels for a couple years now and...have only broken a few spokes !!! but they are $2 each...
I'd go with 721s or 823s if you want to run tubless, laced up to Hope hubs with DT Swiss spokes. I'm running this wheelset on my a Rune and I absolutely love it
