Cane Creek's "10" series headsets are perfectly fine and will give decent service. However, they are no longer listed on Cane Creek's web site so I assume they have been discontinued.

Cane Creek's "40" series headsets are somewhat more expensive and more precise and will give excellent service.

Cane Creek's "110" series headsets are extremely good, in the same league as Chris King's, but VERY expensive and probably not worth the extra cost for most riders.

BrandX? Who knows?
