Chris King don't make an integrated headset because they believe that running the bearings directly in the frame is bad engineering practice. The NoThreadset uses surgical-grade stainless steel cartridge bearings that do a great job.
The FSA Orbit has a lower stack of roller bearings arranged in a taper to handle lateral and vertical loads, and an O-ring is highly effective in protecting the lower bearings from the effects of moisture.
The Solos is the flagship of the Cane Creek headset range, available in both standard and integrated standard versions. Our IS version weighed in under Cane Creek's claimed weights by 4g for both the tall and short versions.
