The number of new tubeless valves on the market is growing. After Muc-Off, Reserve, Stan's and other manufacturers, Peaty's is now also entering the high-flow valve segment. The Holeshot Fast Flow tubeless valves are based on a modified design that is intended to solve the typical problems of classic Presta valves.
The classic Presta valve dates back to the days of narrow racing bike rims and tube systems. Modern tubeless setups with sealing milk and large air volumes have different requirements. Blocked valves, restricted air flow and difficult tyre fitting are among the known weak points of the system.
Valve seal moves inwards
The main change concerns the position of the valve seal. Unlike classic Presta valves, the seal is not located on the outside of the valve stem, but directly at the base of the 7075 aluminium valve stem inside the rim. This design creates a larger sealing surface. Air and sealant can flow directly into the tyre without restriction.
According to the manufacturer, the air flow rate is 200 per cent higher than that of a Presta valve. The higher air volume is intended to seat the tyre faster in the rim well. According to Peaty's, special tools, compressors or special pumps are not required. A normal floor pump is sufficient. Sealing milk can be filled directly into the tyre without removing the valve core.
Protection in the event of damage to the valve stem
The internal valve seal offers a further advantage. Even if the valve stem is hit or damaged by a stone, the seal remains protected and functional. The patented design should be particularly relevant in racing, where damage occurs more frequently. The additional openings at the valve base make the valves compatible with all common rim inserts.
Anti-clogging design through anodisation
Clogged valves caused by sealant are one of the most common problems with tubeless systems. Most riders simply replace clogged Presta valves. Peaty's relies on a different concept. The position and enlarged design of the valve seat are intended to reduce blockages. The valves are fully anodised inside and out. The valve core is made of 316 stainless steel. According to the manufacturer, this combination of materials prevents sealing milk from sticking to the surfaces and blocking the valve.
The design allows complete maintenance at home. After removing the retaining ring, the valve can be cleaned and, if necessary, fitted with new seals. Peaty's offers a lifetime guarantee under the name "Valves for Life".
Additional functions in the valve caps
The Holeshot valves go beyond the pure valve function. The two valve caps supplied fulfil additional tasks. One cap serves as an e-bike lube cap and prevents the crank spider from turning during lubrication. The second cap functions as a spoke spanner for quick repairs on the road.
Despite these additional functions, the valves weigh just 11 grams per pair. According to the manufacturer, this makes them the lightest high-flow valves on the market. Full Presta compatibility allows them to be used with normal floor pumps. CO₂ cartridges work as usual.
Peaty's Holeshot Fast Flow: 3 sizes & 12 colours
The Holeshot Fast Flow tubeless valves are available in three lengths: 42 mm, 60 mm and 42/60 mm MX. The MX version is specially designed for Bosch e-bikes. Twelve Chris King colours are available. The valve stem is made of 7075 aluminium with a stainless steel core. A micro-adjustment function enables precise adjustment.

The opinion of the editorial team - Conclusion
Who invented it? No, in this case it wasn't the Swiss for once. Reserve has already launched a very similar system on the market in 2022 with the Fillmore Valves. Continuous core, closure at the valve base and increased airflow.
In the test, we were able to certify that the Fillmore Valves have more than twice the air flow of classic Presta valves - and similar values can be expected with the new Peaty's valves. Despite the clever additional functions, the Holeshot remains pleasantly light. However, the price of 42 euros is steep.
