Peaty's HoleShot Fast Flow Tubeless Valves - 42mm

Holeshot Fast Flow Tubeless valves: High flow, less faff.

The Peaty's HoleShot Fast Flow Tubeless Valves are engineered to solve one of the most frustrating parts of tubeless setup—poor airflow through traditional valves. Designed by Peaty's, these innovative valves relocate the valve mechanism inside the rim, allowing air and sealant to flow directly into the tyre for dramatically improved inflation performance.

This fast-flow design delivers up to 200% greater airflow compared to traditional Presta valves, making tyre seating significantly easier without needing compressors or special tools. With improved airflow, riders can quickly seat stubborn tyres using the pump they already own.

The internal valve mechanism also prevents sealant clogging, reduces maintenance, and ensures reliable performance over time. Built from a 7075 aluminium shaft with a stainless steel core, these valves are strong, lightweight, and fully serviceable, with no disposable parts.

Compatible with tyre inserts and standard Presta pump heads, the HoleShot Fast Flow Tubeless Valves offer a cleaner, faster, and more reliable tubeless setup for road, gravel, and mountain bikes.

Fail-Safe Design

Built with racing performance in mind, the Peaty’s HoleShot Fast Flow Tubeless Valve is designed to perform under the extreme demands of World Cup competition. Featuring a unique patent-pending design, the “bell house” and valve seal are positioned inside the rim, protecting the valve mechanism from damage if the external shaft is struck by rocks or trail debris.

This fail-safe internal system ensures the valve remains functional even if the shaft is impacted, allowing racers and riders to finish their race run or ride without losing tyre pressure. The internal cage design also ensures full compatibility with all rim inserts, making it ideal for modern tubeless setups used in enduro, downhill, and aggressive trail riding.

More Than Just a Valve

The HoleShot Fast Flow Tubeless Valve is more than a high-flow valve system—it also includes multi-functional valve caps designed for real-world riding situations.

Each pair of valves includes:

1x E-Bike Lube Cap – Designed to prevent crank spider spin during maintenance

1x Spoke Key Cap – Integrated spoke wrench for quick trail-side adjustments

Despite these added features, the HoleShot valves remain one of the lightest high-flow tubeless valves available, weighing just 11 g per pair (42mm).
