Full carbon wheelsets usually aren't the best place to look for value. Goes back to the famous axiom of "light, strong, or cheap: pick two". Giant has managed to buck the trend with their SLR 1 Aero wheelset though.
Full carbon, 1700 grams per set, 23mm wide, 55mm rim profile, and tubeless ready. All for $1200. The hubs are amazingly smooth, nice, and simple. The wheels are UCI and ITU compliant and the minimalist graphics are spot on. We've put them on road and tri bikes and they're a great upgrade for the money.
Giant has arguably more carbon experience than anyone in the game at this point and it really shows in these rims. Stiff, light, and with a great ride quality. If you're in the market for a fast new set of wheels for your bike these should be on your short list.
