With over two years of development and 27 iterations of the final design, you can be assured that every detail and every element has been considered, designed, and optimised to function and perform at the highest possible level by the Peaty's design team.

The patent-pending Holeshot Fast Flow Valve design moves the valve seal inside the rim and uses a flared bell-house shape instead of the traditional straight bore used by most other brands. This creates a larger sealing surface and allows air and sealant to flow directly into the tyre, fast.

In testing, the Holeshot Fast Flow Valve delivered twice the airflow of the Mk2 Presta Valve. The higher, faster airflow makes seating tubeless tyres on the rim easy, first time, every time.

Larger sealing surfaces improve airflow and significantly reduce sealant clogging. All internal and external surfaces are made from 7075 aluminium and fully anodised, which stops sealant from sticking.

No more blocked valves and fewer Presta valves ending up in the bin. Plus, the Holeshot Fast Flow Tubeless Valve is fully serviceable, prolonging its lifespan.

With Peaty’s legacy in racing, the Holeshot valve must perform under the pressures of World Cup competition.

Because the seal sits safely inside the rim, the valve features a fail-safe design. Even if the valve shaft is damaged by a rock strike or crash, the double seal in the bell-house keeps air inside the tyre, allowing riders to finish their ride or race.

The lower internal cage also makes the Holeshot Fast Flow Tubeless Valve compatible with all rim inserts.

Sealant (Peaty’s Holeshot, of course) can be injected through the valve directly into the tyre without removing the valve core, reducing the mess and hassle normally associated with tubeless setups. Combined with the higher airflow, the Holeshot Fast Flow Valves make converting to tubeless effortless.

More ride time, less faff.

Over the years, thousands of Presta valves have been thrown away.

The Holeshot Fast Flow Tubeless Valve is designed to be fully serviceable at home. Simply remove the circlip at the base of the valve, and it can be cleaned (with seals replaced if required). The circlip pliers we use are: Expert by Facom E117920 90° Internal/Inside Circlip Pliers, Min/Max 3–10 mm.

If there is ever an issue or the valve becomes damaged, the Holeshot Fast Flow Tubeless Valves are backed by Peaty’s “Valves for Life” guarantee.

The Holeshot Fast Flow Tubeless Valves vastly reduce the faff and mess often associated with setting up and maintaining tubeless setups.

No special tools are required to fit our valves. They are fully Presta compatible, with no need for a compressor or any modification to your standard track pump.

• For regular inflation, simply use your normal Presta pump.

• For trailside emergencies, CO₂ inflators or hand pumps work as usual.
