Peaty's Holeshot Biofibre Tubeless Tyre Sealant 500ml

Brand:Peaty's

Code:PT-PTS-HBF-500

Peaty’s Holeshot Biofibre Tubeless Tyre Sealant 500ml is a high-performance tubeless tyre sealant developed in collaboration with World Cup mechanics and world champion riders. Designed for mountain bikes, gravel bikes, and road bikes, this advanced sealant delivers fast, reliable puncture protection in the most demanding riding conditions.

Formulated with biodegradable fibres and sealing particles, Peaty’s Holeshot creates a rapid, long-lasting seal by binding with fast-acting latex to form a strong clot, similar to blood platelets sealing a wound. This innovative formula seals punctures and tears up to 6mm, helping riders stay rolling on the trail, road, or race course.

The water-based, ammonia-free latex sealant is non-hazardous, CO₂ compatible, and remains effective inside the tyre for up to 6 months in temperate climates. Unlike traditional sealants, it won’t ball up or clump inside the tyre and can be easily washed out during tyre changes or maintenance.

Suitable for a wide range of setups, Peaty’s Holeshot Tubeless Sealant seals porous tyres and bead-to-rim gaps during installation and performs reliably across a broad pressure range, making it ideal for everything from low-pressure MTB riding to high-pressure road cycling.

  • Biodegradable sealing fibres and platelets
  • Seals punctures up to 6mm
  • CO₂ compatible tubeless sealant
  • Operating pressure: 15–120 psi
  • Operating temperature: -20°C to +50°C
  • Seals porous tyres and bead/rim gaps
  • Long-lasting, easy-clean formula

Technical Information

Setup Instructions:

Always ensure you have tubeless ready rims and tyres. For best results use with Peaty's Tubeless Rim Tape and Peaty's Tubeless Valves.

  1. Shake the bottle vigorously before every use to ensure an even distribution of fibres and particles.
  2. Rinse away any old sealant from the tyre and dry off completely. For brand new tyres degrease, rinse and dry the internal carcass to remove factory mould release agents and other contaminants.
  3. Seat your tyre onto the rim and inflate initially with no sealant, using a track pump, inflator or compressor to pop the tyre bead fully onto the rim.
  4. Deflate the tyre and, with the valve at the three o'clock position, use the flexible injector pipe provided to inject the desired amount of sealant directly through the de-cored valve.
  5. Re-insert the valve core and re-inflate the tyre to desired pressure.
  6. Distribute the sealant around inside the tyre by spinning the wheel and tapping the tyre on the floor.
  7. Listen for any air leaks and orientate the wheel so that the sealant flows around the inside of the tyre to the area required. Continue doing this until you can't hear any more air loss.
  8. Wash away any excess sealant that may have found its way to the outside of the tyre or rim with water.
  9. Check tyre pressures and ride.

Recommended minimum quantities per tyre:

  • Road 30 - 45ml
  • CycloCross 60 - 75ml
  • 26" MTB 60 - 80ml
  • 27.5" MTB 70 - 90ml
  • 29" MTB 100 - 120ml

For wider rim / tyre combinations and / or additional puncture protection Peaty's recommend adding up to 30ml more sealant to the above quantities.

* Always check sealant regularly and top up as required

If a seal can't be made, add more sealant in increments as required
