Zipp Top Cap

The Professional Finish. Iconic Design.

The Zipp Aluminum Top Cap is CNC-machined to exacting tolerances, providing a flush, aerodynamic fit atop your steerer tube. Whether you’re finishing a new build or replacing a generic plastic cap, the Zipp Top Cap provides the structural integrity needed for precise headset pre-load.

Why the Zipp Top Cap is the Perfect Final Touch:

• CNC-Machined Aluminum: Provides a rock-solid platform for setting your headset tension, ensuring your bearings stay aligned and rattle-free on rough roads.

• Seamless Integration: Specifically contoured to match the diameter and aesthetic of Zipp stems, creating a continuous, sleek line from the spacers to the bolt.

• Iconic Zipp Branding: Features the laser-etched Zipp logo, instantly elevating the look of your bike and signaling a commitment to speed and quality.

• Lightweight Performance: Engineered to be as light as possible without sacrificing the strength required to maintain a secure front-end setup.

• Universal 1-1/8" Fit: While optimized for Zipp stems, it fits all standard 1-1/8" threadless steerer tubes, making it an easy aesthetic upgrade for almost any road or gravel bike.

• Durable Anodized Finish: Built to resist corrosion from sweat and road salt, ensuring your cockpit stays looking "showroom fresh" for seasons to come.

Technical Specifications:

• Material: 6061-T6 Aluminum

• Compatibility: 1-1/8" Threadless Steerer Tubes

• Interface: Standard Counter-Sunk Bolt (Bolt often sold separately or with stem)

The Alegro Perspective: In the shop, we say that a build isn't finished until the top cap matches the stem. It's the one part of the bike you look at more than any other while you're riding. Swapping a generic, scratched-up cap for a genuine Zipp piece is the fastest, most affordable way to make your cockpit feel "elite." It’s a small detail that makes a massive difference in the overall "vibe" of your machine.
