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.
The 40 Series ZeroStack Conversion Headset enables the use of a 1 1/8-inch fork steerer tube on frames with a 1.5-inch ZeroStack head tube.
