Cane Creek ZS3 1 1/8in Black Headset w/ Interlock $60.00
A low stack height is essential for contemporary twent- niners to keep the center of gravity as low as possible. Cane Creek's ZS3 1-1/8in Headset w/Interlock is a zero-stack design, so you can run your stem slammed.
Constructed from aluminum, the ZS3's cups are plenty light with precision machining to ensure an excellent fit in high-end frames, and so its cartridge bearings have prefect alignment for proper preload. The bearings are black oxide-coated to add durability, and low-friction seals keep the crud out.
The Cane Creek ZS3 Black Headset w/ Interlock comes with a top cap and spacers. It will only fit standard 1-1/8in headtube frames.
