Cane Creek 10 EC49 Headset

EC49 stands for External Cup with a 49mm head tube inner diameter. This means the headset cups press into the outside of your frame's head tube rather than sitting flush inside it, which is common for frames designed to accommodate 1.5-inch steerer tubes.

This specific model is designed for a 1.5-inch straight steerer tube, indicated by the 39.79mm crown race diameter. If you have a tapered fork, you would need a different headset configuration that supports a 1.125-inch upper and 1.5-inch lower setup.

The black-oxide coating provides an extra layer of corrosion resistance compared to standard steel bearings. When paired with the integrated seals, this headset is well-equipped to handle moisture and trail grit, though regular maintenance is still recommended for longevity.

Yes, the Cane Creek 10 EC49 includes the necessary crown race. Ensure your fork's crown seat diameter matches the 39.79mm specification before installation.

The total stack height is 28mm. This measurement is important because it dictates how much steerer tube length you need on your fork; if your steerer is already cut short, you must ensure you have enough length to accommodate this stack height plus your stem.
