The Inset headset offers Chris King's trademark quality and durability in a low-stack configuration sized for contemporary headtube dimensions. King's legendary made-in-house bearings still form the centerpiece of the Inset headsets, with precision machined aluminum cups and headset caps available in all ten classic Chris King colors. The Inset 1 is compatible with non-tapered 1-1/8-inch forks and frames using a 44mm headtube.

Origin-8's Pro Pulsion Carbon Expander is an expander and top cap for forks with carbon steerers. Instead of a traditional star nut (which will damage carbon), the Expander snugs tightly and safely in place in the fork for easy and accurate headset adjustments. Plus, it actually strengthens the fork. It fits most 1 1/8-inch forks, and includes a top cap with a stainless-steel bolt.

Every threadless headset needs one, so make a stylish statement with Salsa's ABB Top Cap. The anodized cap fits standard 1 1/8-inch headsets and each design is laser-etched.

Super-smooth steering, quality materials, cutting-edge design and serious durability are all hallmarks of Cane Creek headsets. The 40 Series has light, tough, and beautiful machined 6061 T6-aluminum cups that are internally relieved for even more gram shaving. You also get Cane Creek's corrosion-resistant black-oxide sealed bearings and quality seals throughout to keep the grease in and the dirt out, including Cane Creek's Clip Seal that completely seals the top assembly.
