DURABILITY AND VALUE. Cane Creek’s 40-Series sets the standard for performance, durability and value. Drawing from the premium 110-Series design, the 40-Series includes all the features necessary for a durable, lightweight, long-lasting headset. We make it easier, by developing consistent graphics, interchangeable parts and over 40 configurations to meet almost every size need. Sold in straight and tapered assemblies or tops & bottoms, tops are available in either short (9mm) or tall (15mm) stack height bearing covers, Cane Creek’s 40-Series offers the largest fitment range of any headset line on the market. Precision engineered by Cane Creek in Fletcher, NC. NEW! The new ZN40 bearings are a zinc-coated, machined steel cartridge bearing with hardened steel balls. The new material is much more corrosion-resistant, which vastly increases the longevity of the 40 series headsets.
