The external threaded ZS (Zero Stack) design conforms to SHIS standards (EC44/28.6 | ZS56/40), ensuring compatibility across a broad spectrum of components.

Style & Use Case

The black anodized finish grants a sleek, aggressive look suited for trail, mountain, gravel, and cyclocross bikes. Its adjustable angle head tube design makes it ideal for riders seeking precise geometry customization for steep descents, technical climbs, or aggressive riding styles. Whether upgrading an existing bike or building a custom setup, this angleset improves handling and rider control.
