With more builders, manufacturers and riders asking for full internal routing of cables and brake lines, Chris King has released two more headsets to bring this option to a much wider array of frames. AeroSet 1 fits headtubes with IS52/IS52 upper and lower and 45 x 45 degree bearing sizes. AeroSet 2 is the same but with a lower bearing spec of 36 x 45 degrees.
The new AeroSets feature King's GripLock technology which protects a fork's steerer tuber from excessive preload and protects the headset bearings from excessive shock load while riding. The system uses two isolated wedges to isolate headset bearing adjustment from the steerer tube location. GripLock solves the problem of loose headsets on long-travel mountain bikes and also eliminates the chance of headset inflicted fatigue on the lightweight carbon steerer tubes found on modern road forks.
AeroSet™ 1 and 2 are integrated headsets, similar to King’s DropSet™ series, which have been in the market for years. The new headsets are available for both the ENVE In Route and FSA ACR internal routing systems. They share the AeroSet™ 3 bearing cap that was launched in 2022 which uses 44mm press-in cups found on many custom framebuilder bikes, AeroSet 1 and 2 fit bikes from ENVE, Argonaut, Baum, Time, and more.
AeroSet™ 1 and 2 are available to order soon in the full array of King’s 2024 colors.
