The Chris King NoThreadSet Headset has been setting the standard for threadless headsets since Chris King introduced the concept decades ago — a track record that shows up in the details. Aluminum cups, bearing cap, and stem cap are built around Chris King's stainless steel sealed bearings, with a stainless steel baseplate and custom starnut included in the box. The result is a headset that installs cleanly, runs smoothly, and lasts long enough that you'll likely be replacing the bike around it. Available in both 1" and 1-1/8" steerer sizes, the NoThreadSet fits road and mountain applications equally well. The range of finish options — from matte black to Sotto Voce 3D Violet — reflects the same attention to detail that goes into the engineering. At 84g for the 1" and 98g for the 1-1/8", it's not a weight-weenie piece, but what you're buying is longevity and precision that cheaper headsets simply don't deliver over thousands of kilometers.
