Chris King NoThreadSet

This headset is designed for frames with a 44mm head tube inner diameter that accept a 1-1/8 inch to 1-1/2 inch tapered steerer tube. It uses an external cup (EC34/EC44) configuration, so verify your frame's specific head tube standard before purchasing.

The patented GripLock system uses a split-ring design that isolates the steerer tube from the headset bearing. This ensures your headset adjustment stays secure even under heavy braking or rough terrain, preventing the loosening often found in simpler designs.

These bearings are fully serviceable. You can remove the seals, clean out the old grease, and repack them with fresh lubricant, which is why Chris King headsets are known to last for many years of heavy use.

Yes, using surgical-grade steel allows for tighter manufacturing tolerances. Because the races are machined simultaneously, the bearings have a near-perfect fit that actually improves and smooths out as you ride, rather than degrading over time.

Yes, the GripLock system is compatible with carbon fiber steerer tubes. The design provides even, consistent pressure that avoids the stress concentrations that can damage carbon components.

Because of the high-quality seals and precision manufacturing, this headset requires very little attention. A simple cleaning and re-greasing once a year is usually sufficient for most riders, though you should service it more frequently if you regularly ride in wet or muddy conditions.
