Product Details

Overview & Technology

Stan's NoTubes 44mm Presta tubeless valves are built for reliable, repeatable tubeless setups. Each pair features a precision-machined aluminum stem and a molded rubber base that creates an airtight seal against rim tape or rim beds. At 44mm length they are sized to clear deeper-section and modern rim profiles while keeping weight and profile low. The valve's construction is optimized for tubeless sealant compatibility and easy maintenance. The machined stem provides a secure fit for pump heads and valve caps, while the rubber grommet compresses to form a consistent seal—minimizing leaks and helping you maintain pressure for longer rides.

Key Features

Durable materials and serviceability: The 44mm stems are CNC-machined aluminum for lightweight strength, paired with a resilient molded rubber base that seals to rim tape and ZTR rim beds. The valves are sold as a pair for single-wheel swaps or replacement. • Valve type: Presta thread for high-pressure compatibility. • Length: 44mm — suited to most modern rim depths. • Compatibility: Designed with Stan's ZTR rims in mind, but fits most tubeless-ready wheels that accept Presta valves.

Fit & Compatibility

These Stan's valves are Presta (French) valves and fit rims with a standard Presta valve hole. The 44mm length gives plenty of clearance for deep-section rims or helmets with inner rim tape stacks. They form an airtight seal on Stan's ZTR rims and are compatible with most tubeless-ready rims when paired with correct rim tape or grommets. If you run very shallow rims or want a lower-profile stem, Stan's also offers 35mm and Schrader variants in bulk and pair formats. For tubeless service, the valve core is removable for easy addition of sealant and cleaning; use a valve core tool for safe removal and reinstall.

Who It's For

This valve pair is ideal for mountain and trail riders using tubeless setups who need reliable seals on modern rim profiles—especially those running Stan's ZTR rims or similar designs. They suit riders upgrading from worn rubber stems or converting wheels to tubeless. Shops and mechanics will appreciate the availability of bulk 25-pack options for high-throughput wheel builds, while home mechanics will value the pair format for quick replacements and maintenance jobs.

Frequently Asked Questions

Are these valves compatible with Stan's ZTR rims?

Yes. These valves are specifically compatible with Stan's ZTR rim series and are sized to work with standard Presta valve holes. They also work with most other tubeless-ready rims that accept Presta valves when used with proper rim tape or grommets.

Do the valve cores remove for adding sealant?

Yes — the valve cores can be removed with a standard valve-core tool. Removing the core makes adding tubeless sealant, bleeding, or cleaning much easier and is the recommended method for service.

Will 44mm be too long for my rim?

44mm is chosen to clear deep-section rims and most modern rim+tyre combinations. For very shallow rims you may prefer the 35mm variant to avoid excess stem length. Always measure from rim bed to expected cap height when in doubt.

Are these valves reusable?

Yes. With proper care — keeping the rubber base clean and replacing the valve core when necessary — these aluminum-stem valves are reusable and intended for long-term tubeless setups.

Do they come with lock nuts and caps?

This particular product is sold as a pair of valve stems. Check the variant or product description for included lock nuts or caps — many Stan's valve stems include a lock nut, but provisions vary by SKU and bulk pack options.

Can I use these with tubeless tape and standard rim preparation?

Absolutely. These valves seal to tubeless tape or a sealed rim bed. Ensure the tape is properly applied and the valve hole is clean before installing the rubber base to achieve an airtight seal.

Buying Guide

Choosing the right tubeless valve means matching valve length and type to your rims and riding needs. Presta valves are the standard for road and mountain tubeless systems; select a length that clears your rim and any rim strip or tape stacks. If you swap wheels between shallow and deep rims, consider keeping multiple lengths on hand. For shops or frequent builders, bulk packs reduce per-item cost. Also confirm whether the valve includes a lock nut and whether the core is removable — removable cores simplify adding sealant and maintenance. Finally, pick valves with durable stems and robust rubber bases for long-lasting, leak-free performance.
