Product Details

Overview & Technology

Zipp Vuka Alumina End Plugs are precision-machined handlebar end closures designed to tidy your cockpit and provide a secure interface for cable routing on Vuka extensions. These plugs include an integrated cable guide that keeps brake or shift housing exiting the extension cleanly, reducing abrasion and rattling on long rides. Manufactured from CNC-machined billet aluminum and finished with a hard-anodized coating, the plugs resist corrosion and wear while staying featherlight. The low-profile shape preserves aerodynamics and maintains the sleek look of your Vuka extensions while offering a robust, serviceable end cap solution for road and time-trial setups.

Key Features & Benefits

Integrated cable guide: Built-in guide channels routing for mechanical cables (or housing ends) to minimize chafing and maintain a tidy, aerodynamic line at the extension tip. This is especially useful on older Vuka setups or custom cable runs. Durable construction and easy installation: The plugs are CNC-machined for a precise fit, and the anodized finish increases scratch and corrosion resistance. Installation is push-fit; once seated they stay secure under normal riding loads while remaining removable for maintenance.

Fit, Compatibility & Specifications

These end plugs are made specifically for Zipp Vuka extensions and list SRAM Model ID: HB-SPP-A0 for cross-reference—making them an OEM-compatible replacement or upgrade. They come as a pair and include the integrated cable guide. Check the diameter and internal lip of your extension: these plugs are intended for standard Vuka extension internal profiles. Shipping dimensions: 5.6" x 3.8" x 0.7". Packed weight: 0.07 lb. Manufacturer part #: 00.6618.045.000. Product number: 170350.

Who It's For

These end plugs are ideal for road and time-trial riders who use Zipp Vuka bar extensions and want a tidy, reliable finish at the tip of their extensions. Whether you're a triathlete chasing marginal gains in aerodynamics or a road racer who values a clean cockpit and secure cable routing, these plugs deliver a small but meaningful upgrade. They also suit mechanics and frame builders who need OEM-compatible replacement parts for service and restoration projects. If you run electronic shift with no exposed cables, these still work as premium closure plugs to complete the look of your extensions.

Frequently Asked Questions

Are these plugs compatible with all Zipp Vuka extensions?

These plugs are designed for standard Zipp Vuka extension internal profiles and cross-referenced to SRAM Model ID HB-SPP-A0. While they fit most Vuka variants, check your extension's internal diameter and lip profile to confirm compatibility before purchase.

Can I use these with electronic shifting setups?

Yes. If you run electronic shifting with no exposed mechanical cables, the plugs will still function as high-quality closure caps to finish the extension ends and preserve aerodynamics. The integrated cable guide simply remains unused.

How do I install and remove the end plugs?

Installation is push-fit: align the plug with the extension opening and press until the lip seats securely. Removal typically requires a thin pick or small flat tool to lever the plug out gently—take care not to damage the anodized finish or the extension's internal edge.

What maintenance do these end plugs need?

Minimal maintenance is required. Periodically check that the plugs remain seated and free of debris. Clean with mild soap and water; avoid harsh solvents that can affect anodized surfaces. Replace if the fit becomes loose due to wear.

Do these plugs include any fasteners or adhesive?

No additional fasteners or adhesives are included—the design relies on an interference fit to stay in place. If you prefer a more permanent installation, a small dab of bicycle-appropriate threadlocker or non-permanent adhesive can be used carefully.

Buying Guide

When buying replacement end plugs for aero extensions, prioritize fit and material. CNC-machined aluminum plugs like the Zipp Vuka Alumina offer a good balance of strength, weight savings, and finish durability—important for maintaining both function and cockpit aesthetics. Confirm the manufacturer part number or model ID (for this product, SRAM HB-SPP-A0 cross-reference and Zipp part 00.6618.045.000) to ensure an OEM-quality match. Consider whether you need an integrated cable guide—if you run mechanical cables through your extensions it's essential. Also decide if finish and corrosion resistance matter for your riding conditions; an anodized aluminum plug will outlast cheap plastic alternatives while keeping weight low.
