Zipp, enve, fwd, reynolds, mavic all do disc brake wheels in clincher and tubs.At a rough guess that would cost me @ £5000 not including the cost of the brakes .
Theres also the handbuilt option with chris king, royce, hope hubs, as well as the novatec option for the commuter/winter wheels too. Even better still is none of them will suffer from rim wear in the soggy winter weather from salt, road grime.
