Chris King NoThreadSet

This refers to the Standardized Headset Identification System (S.H.I.S.). It indicates that your frame uses an external cup design with a 34mm upper cup diameter and a 44mm lower cup diameter, specifically designed to accommodate a tapered 1-1/8" to 1-1/4" steerer tube.

The patented GripLock system uses a split-ring design that isolates the steerer tube from the headset bearings. This prevents the headset from loosening over time and protects your steerer tube from damage, ensuring your adjustment stays consistent even on rough terrain.

While the bearings are fully serviceable, they are designed to be durable and long-lasting. You can clean and re-grease them with standard shop tools, but Chris King recommends using their specific headset service tool for the easiest and most precise maintenance.

Yes, this product is covered by the King Lifetime Warranty, which protects against defects in materials and workmanship for the original owner.
