The Ritchey WCS Top Cap 1 1/8 is a precision headset accessory designed to complement your steering system with lightweight durability and refined style. Engineered for use with 1 1/8-inch steerer tubes, this top cap provides secure compression when paired with a compatible star nut or compression plug, helping maintain proper headset preload and smooth steering performance.

Part of Ritchey’s World Championship Series (WCS), the top cap is crafted with attention to both aesthetics and function. Its clean, machined design adds a subtle performance look to your cockpit while the black anodized finish offers corrosion resistance and long-lasting durability. Whether you’re building a new bike or refreshing your current build, the WCS top cap ties together the headset stack with reliable, precise fit.

Easy to install and compatible with most 1 1/8-inch systems, the Ritchey WCS Top Cap helps ensure consistent bearing preload, which is critical for eliminating play and maintaining smooth steering feel under load. Lightweight yet robust, it’s a small but essential piece of your front-end assembly that supports confident handling on road, gravel, or mixed terrain.
