With design cues from Chris King's headset cups and bearing caps, these collars are machined from aluminum in the USA, finished with the King logo and a cheeky little bee etched on the barrel nut.

Easily adjusts for optimal thread alignment and clamping force, because that's what seatpost collars do.
