Know before you buy
This indicates the headset is designed for a frame with a 44mm internal diameter at the top of the head tube and a 49mm external cup diameter at the bottom. You must measure your head tube dimensions accurately to ensure this specific configuration fits your frame.
The zero stack design sits flush inside the head tube, which keeps your handlebar height lower compared to external cup headsets. This provides a cleaner, more streamlined aesthetic and allows for a lower stack height if you are looking to adjust your cockpit geometry.
Compatibility depends on the specific crown race and top cover included with your setup. The EC49 bottom cup is typically designed to accommodate a tapered steerer tube, but you should verify your fork's steerer diameter before installation.
Yes, the Cane Creek 40 Series comes as a complete kit, including the upper and lower cups, bearings, crown race, and necessary seals. It is ready for installation right out of the box.
Yes, installing this headset requires a professional-grade headset press to safely seat the cups into your frame without causing damage. If you do not have access to a press, most local bike shops can handle the installation quickly.
