Overview & Technology

Zipp Disc Wheel Valve Adaptor (Part #11.1918.031.000, Prod 030070) is engineered to deliver a more reliable, longer-lasting seal on Presta valve stems used in disc wheel setups. At its core is a synthetic elastomer gasket that offers 2× the holding power and 5× the wear resistance of traditional gasket materials, reducing leaks and the need for frequent replacements. The adaptor uses a two-stage seal design and an adjustable compression cap so you can tighten the unit as the gasket wears, increasing holding power up to 4×. A 15° stem angle lowers strain from pump hoses and inflator heads, improving stability when pumping and reducing the chance of valve damage during roadside inflation. SRAM Model ID: WH-SPP-A0 — fits Zipp and most Presta valve systems on disc wheels.

Key Features & Real-World Benefits

Material and design: The synthetic elastomer gasket resists abrasion and deformation, maintaining a consistent seal under repeated inflation cycles and high hub rotation. The two-stage sealing geometry improves initial seating and secondary retention under pressure — that means fewer burps, less air loss, and a more dependable tubeless or tube setup. Adjustable compression lets you compensate for long-term wear: turn the cap to ramp up holding force for a tighter fit, or dial it back for easier removal. The 15° stem angle takes the sting out of pumping — your hose pulls won’t torque the valve stem or shift rim tape, which matters on deep-section disc rims and tight cockpit setups.

Fit, Compatibility & Installation Notes

This adaptor is built for Presta valve stems and is commonly used on Zipp disc wheels (SRAM Model ID WH-SPP-A0) but is compatible with most standard Presta valves when used as intended. It works with both tube and tubeless setups provided the valve is a conventional Presta size and thread. Confirm the valve stem protrudes enough through the rim center to accept the adaptor and allow the cap to compress the gasket. Installation is straightforward: seat the gasket over the valve stem, hand-thread the adaptor and then turn the compression cap until snug — avoid excessive force. The adaptor's 15° offset helps align pump hoses and inflators; shipping dimensions 6.6" x 5" x 3.2", weight 0.6 lb. Manufacturer Part #: 11.1918.031.000.

Who This Adaptor Is For

Riders running disc wheels — especially road and time-trial/triathlon racers using deep-section rims — who demand a secure, durable valve seal will benefit most. It’s ideal for cyclists who frequently set up tubeless systems, travel with their wheels, or use high-pressure road pumps where valve stability matters. Mechanics, club racers and riders who prefer a serviceable solution over disposable adaptors will appreciate the adjustable compression and long-wearing elastomer. If you want less downtime, fewer leaks and better pump ergonomics during inflation, this adaptor is a smart upgrade.

Frequently Asked Questions

Will this adaptor fit any Presta valve?

Yes — the Zipp Disc Wheel Valve Adaptor is designed for standard Presta valve stems and will work with most rims that accept Presta valves. Ensure the valve protrudes enough from the rim so the gasket can seat properly and the cap can compress to form the seal.

Is this compatible with tubeless valves and setups?

The adaptor works with tubeless setups as long as you have a standard Presta valve stem installed. It helps maintain a secure seal during inflation and reduces the risk of hose movement disturbing the valve or rim tape during high-pressure pumping.

How do I install and adjust the compression cap?

Hand-thread the adaptor onto the Presta valve, then turn the compression cap clockwise until it feels snug. The cap increases contact pressure on the gasket; tighten incrementally to avoid over-compressing. If you notice leaks over time, tighten a bit more to compensate for wear.

Can I use CO2 inflators or frame pumps with this adaptor?

Yes — CO2 inflators and frame or floor pumps work well. The 15° stem angle improves hose alignment and reduces stress on the valve stem during inflation. For CO2 cartridges, ensure the inflator head mates cleanly with the valve and that the adaptor is securely seated before firing.

How long will the gasket last?

Gasket life depends on usage, frequency of inflation, and environmental exposure. The synthetic elastomer provides up to 5× the wear resistance of traditional materials, but the adjustable compression cap is designed to extend service life by restoring holding power as the gasket gradually compresses.

Is there any risk of damaging the valve if I overtighten?

Excessive force can stress the valve stem. Tighten the cap until the seal is secure but avoid using tools to force it. The 15° angle already reduces lateral stress; moderate hand-tightening is sufficient for a durable, leak-free seal.

Buying Guide

When choosing a valve adaptor for disc wheels, prioritize material durability and sealing design. Synthetic elastomer gaskets and two-stage seals give the best combination of initial leak prevention and long-term retention. An adjustable compression cap is valuable — it lets you restore holding power as components wear without replacing the whole adaptor. Also consider valve angle and pump ergonomics. A slight offset (like 15°) reduces lateral stress on Presta stems and makes pumping easier on deep rims. Finally, confirm compatibility with your valve length, tubeless or tube setup, and the rim's valve bore before purchase.
