Peaty's Holeshot Tubeless Conversion Kit

Tubeless tires have revolutionized the way many people ride both road, gravel and mountain bikes – and a key part of the tubeless system is the tubeless fluid. It’s the invisible hero that constantly works inside the tire to ensure you can ride tubeless, with lower tire pressure and far fewer punctures. Tubeless fluid makes it possible to seal small holes and cracks in the tire in real time, so you often don’t even realize you’ve had a puncture while you’re on the road.

Whether you’re racing or training, tubeless fluid helps increase reliability and reduce the risk of interrupted training or flat tires. That means more time on the bike and less time in the ditch – and that’s something most riders appreciate. With the correct amount and maintenance, the fluid gives you peace of mind, regardless of the surface or weather conditions.

Tubeless fluid is typically based on latex or similar polymers that, when in contact with air and movement, coagulate and seal holes in the tire. As you ride, the fluid will constantly move around the tire, and if a small nail or sharp rock punctures the fluid will immediately seal the opening – often without loss of pressure. It is this self-sealing property that makes tubeless construction so popular, especially among gravel and off-road riders, where the surface is uneven and risky.

But tubeless fluid is not a “fit and forget” solution. Over time, the fluid dries out or loses its effectiveness – especially in hot or dry climates. That’s why it’s important to check the level regularly and top up with fresh fluid every two to three months, depending on the amount of riding and conditions. Some people also choose to remove the old fluid completely and fill it with fresh fluid if there is a lot of dirt or clumps left in the tire.

Additionally, you need to pay attention to compatibility with your tires and rims – although most modern systems today are designed to work seamlessly together. A tight and properly mounted tubeless setup combined with the right amount of fluid is the key to a stable and safe setup that you can rely on mile after mile.

One of the biggest benefits of tubeless and using liquid is the ability to run lower tire pressures without the risk of snakebites or pinch flats. This provides better grip, increased comfort and lower rolling resistance – especially on uneven or loose surfaces. For road cyclists, this can mean fewer punctures, while gravel and MTB riders gain better control and stability on technical trails and uneven surfaces.

Tubeless fluid is also cheap insurance against those small but annoying punctures that would otherwise require tube changes or CO2 cartridges on the ride. Many riders experience fewer stops and less time spent patching – and more continuous training. This can be a clear advantage both mentally and physically.

It requires a little extra maintenance and understanding of setup, but once the system is running stably, it’s hard to go back to tubeless tires. In short, tubeless fluid helps ensure your setup is efficient, fast and ready for the unpredictable – whether you’re training in all weather or racing where every second counts.
