White Industries ZS/EC Headset
Best premium upgrade for cyclists building a long term custom bike.
This hybrid headset is the ultimate problem solver for running a tapered fork in a straight 44mm head tube. While it requires a bit more attention to frame compatibility than a standard drop-in, the US-machined durability and tool-free split crown race make it a reliable, long-term upgrade for any serious build.
