These Zipp 404 clinchers are the best wheels I've personally ever ridden. Very fast and stable. They feel great on the bike. Zipp 404 clinchers are 58mm deep rims that only weigh 1615 grams/set (with regular hubs, mine have a Powertap SL rear hub). Arguably the best all around wheels you can buy in my view.

These are pricey new ($2000+) but you can buy them slightly used on eBay all day long for much less.
