The Holeshot Fast Flow Valves

High Flow, Less Faff

Head to the bottom of this article to read our First Ride review

Introducing the Peaty’s Holeshot Fast Flow Valve, a tubeless valve engineered specifically for tubeless setups from the ground up. After two years of development and over 27 design iterations, Peaty’s design team refined every detail to maximise airflow, reduce sealant clogging, and ensure ease of use and maintenance.

Fast Flow

The patent-pending design moves the valve seal inside the rim and uses a flared bell-house shape instead of a traditional straight bore. 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 200% more airflow than the Peaty’s Mk2 Presta Valve (see Below Image 1.1). The higher and faster air flow makes seating tubeless tyres on the rims easy, first time, every time.

Anti-Clog Construction

Larger sealing surfaces promote flow and vastly reduce sealant clogging. To further enhance this, all internal and external surfaces are made from 7075 aluminium and fully anodised, reducing the sealant’s ability to stick to surfaces.

That means no more clogged valves and Presta valves being thrown into the waste. The Holeshot valve is also fully serviceable, if required.

Fail-Safe Design

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.

Less Faff

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 a doddle. More ride time, less faff.

Compatibility

The lower cage helps direct air and sealant into the tyre and also means the valves are fully compatible with:

All tyre inserts
Tyre pressure gauges
CO₂ inflators

Holeshot Fast Flow Valves are also fully Presta compatible, so you can use a standard track pump, or compressor without any adaptors. The Holeshot Fast Flow Valve is also fully compatible with Presta hand pumps for trail side top ups.

Service, Not Waste

Holeshot Fast Flow is built to be fully serviceable, not disposable. Simply remove the circlip at the base and the internal core can be removed to clear dried sealant, replace worn parts (service kits are available) and restore full airflow. It’s a simple, workshop-friendly design that extends product life, reduces waste and keeps one set of valves running for years.

All Holeshot Fast Flow Valves are backed by Peaty’s Valves for Life Guarantee.

Release And First Ride: Peaty's Holeshot Fast Flow Valves

More Than a Valve

Each pair includes a unique e-Lube valve cap as well as an integrated spoke key cap for trailside repairs. The e-Lube cap fits a T30 or 6mm bolt pattern and is designed to fit in the chain ring bolt for the cranks to back pedal against when cleaning and lubricating the chain. When loosened, the cap allows riders to micro-adjust tyre pressures on the trail.

Available Now

The Holeshot Fast Flow Valves are available in 12 stunning Chris King colours and three size configurations (42 mm, 60 mm, and MX – 42/60 mm for Bosch eBikes).

FIRST RIDE

Peaty’s Holeshot Fast Flow Valves

First Ride by Robert Johnston

Nobody is pretending that the new Peaty’s Holeshot Fast Flow Valve – or any tubeless valve for that matter – is going to revolutionize your ride from a performance standpoint. However, I have had a couple of rides cut short by broken valve stems in my time, which could have ended differently had I been using Peaty’s new valve offering. Having to walk out of a ride with a flat tire is inconvenient, but for riders with a race result on the line, eliminating a potential source of a flat is likely to be even more attractive.

Aside from the misfortune of a stray rock or log snapping an alloy valve stem, there are a couple of improvements the Peaty’s Holeshot Fast Flow Valves provide that are welcome from a usability standpoint in the day-to-day. When mounting the tires, you can directly inject sealant through the valve stems with no need to play with removing a core (verified with Peaty’s Holeshot and Joe’s No-Flats Super Sealant), nor need to pull the core for tire seating. That also means that there is no core to worry about coming undone when removing thread-on pump heads, an issue I coincidentally sustained the next time I pumped up a tire with a regular tubeless valve.

It’s only early days with the Peaty’s Holeshot Fast Flow Valves, so time will tell whether they can resist clogging and continue to operate as effectively as when new. But so far, you can consider me very much impressed. Improvements to user-friendliness and reduced likelihood of clogging or breaking, with a failsafe valve design in case you manage to take a valve-snapping hit, and available in a range of pretty colors at a fairly typical price, what’s not to like?
