+1 for Industry Nine

I switched from the stock DT Swiss-es that came on my bike to the I9 Ultralites and went tubeless at the same time: dropped a pound off each wheel. My riding, yes, improved dramatically.

And that hub! Oh my goodness, the engagement is instantaneous.

They are *not* cheap, but I have never never never regretted the purchase.

-- gnat! (the pink spokes make you go faster, too)
