Cane Creek 40 ZS44-28.6 EC49-40 Tapered Headset

Cane Creek has developed a great system for identifying headset requirements, selling both upper and lowers to match the many variations on the market today. This headset is packaged as a complete, featuring a Zero Stack 44mm drop-in upper that works with steerers that taper to 1 1/8 inch (28.6mm). The lower is a press-in EC49 1.5" for tapered steerers. Your frame dictates the requirements so, the frame must call for a ZS44 upper, and an EC49 press in-lower. Many current Santa Cruz and Intense frames, as well as many others, use this system.

As you would expect with a quality 40 series headset from Cane Creek, the bearing carriers are contoured and relieved 6061-T6 aluminum for minimized weight and maximized strength, and feature excellent split-lip sealed stainless steel bearings. Low friction, Dual-Seal crown race and top cover units seal out contaminants, and the captured compression ring design is fully compatible with carbon steerer tubes. Installed properly, the 40 Series headsets deliver incredibly smooth action, and excellent bearing life. For the price, it hard to beat a 40 series headset.
