Aheadset was originally made by Dia Compe. THe name Cane Creek came later. Maybe Tange licensed the use of the design, but I don't think they ever actually used the name.

Back in the day Dia Compe 'Aheadset' headsets were quite good, and so were some others, but a handful came out with 'me-too' threadless systems where the adjustment system was terrible and unreliable.
