i actually sent carbonsports an email a while back,

the reason that the lightweight track wheels haven't been made available yet is that they're trying to develop a more durable spoke, given the greater likelyhood of crashes on the track than the road. on the low spoked lightweight wheels, if you shear or damage a single spoke, the whole wheel is toast and completely unrepairable. they also don't sponsor or give out freebies.

fwiw, they beleive that their disc wheel is going to offer unparalelled performance benefits. generally speaking, disc wheels tend to be heavier, less radially stiff, less laterally stiff, and than a 36h spoked wheel. they also have less efficient power transfer from the hub to the rim. of course this is offset by aerodynamic resistance magnitudes lower than spoked wheels. apparently they have the data to prove that their disc wheel is radially & laterally stiffer, more efficent at power transfer, far more aerodynamic, and about the same weight as a 36h 3x lightweight tubular.

time will tell, but when lance, jan ulrich, and ivan basso were using their climbing wheels, it was on the d.l.
