Chris King AeroSet Integrated Headset


Chris King AeroSet Integrated Headset

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 (Patent Pending) fits headtubes with IS52/IS52 upper and lower and 45° x45° bearing sizes. AeroSet™ 2 (Patent Pending) is the same but with a lower bearing spec of 36°x45° degree…

The new AeroSets™ feature King’s GripLock® technology, which protects a fork’s steerer tube from excessive preload and 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.
