Peaty's Holeshot Biofibre Tubeless Tire Sealant - Fast, Durable Repair

In this review Peaty's Holeshot Biofibre Tubeless Tire Sealant is assessed for riders who want a fast, reliable puncture solution that stays in the tire. The bottom line: this sealant is best for mountain, road and gravel cyclists who value rapid sealing and durability because its added biodegradable fibers and sealing particles create a faster, stronger plug that can handle holes and tears up to 6mm. It is designed and made in the UK, water-based and ammonia-free, and aims to reduce time spent fixing flats so riders can return to the trail.

Key Features

• Biofibers: Fibers tangle with particles and latex to form a quicker and more durable seal that helps stop holes and tears up to 6mm.
• Fast-acting latex: The updated water-based formula works quickly to seal punctures so riders spend less time on roadside repairs.
• Thinner formulation: A slightly thinner viscosity makes initial tubeless setup easier and helps the sealant coat the casing evenly.
• Long lasting: Non-hazardous and ammonia-free, the sealant is formulated to last up to 6 months in temperate climates without balling up.
• Easy to clean: The water-based formula washes out of tires readily when you need to remove or replace it.

Who It's For

Peaty's Holeshot is aimed at riders who run tubeless setups on MTB, road or gravel bikes and need a dependable in-tire solution for common punctures and small tears. World Cup mechanics and champion riders helped develop it, so it suits people who expect race-grade performance and quick fixes during rides.

Those who should look elsewhere include riders who prefer an oil-based or plug-only approach, or who live in very hot or very cold climates where longevity may differ; also users who need a sealant specifically formulated for extremely large cuts beyond 6mm should consider complementary repair options.

Pros & Cons

Pros

• Very effective sealing thanks to biofibers and concentrated sealing compounds.
• Faster setup and even coverage with the thinner formulation.
• Water-based, ammonia-free composition that is easier to wash out and non-hazardous to handle.

Cons

• Some users report mixed durability or occasional quicker drying in certain conditions, so longevity can vary by climate.
