With a formula tweaked to perfection by World Cup mechanics and legendary racers, Peaty's Holeshot BioFibre Tubeless Tyre Sealant delivers superior performance in sealing your bike tyres. Filled to the brim with planet-friendly, biodegradable fibres and sealing particles, this sealant ensures a speedy and robust seal.

Our revolutionary sealant harnesses the power of the latest fast-acting latex to provide a water-based solution that is ammonia-free and non-hazardous. Despite its gentleness on the environment, this sealant retains its power for up to 6 months in temperate climates* without forming lumps inside the tyre and cleans out easily.

Our green-friendly fibres and particles collaborate with the lightning-fast latex, forming a clot - mirroring the platelets in your blood - to quickly and effectively seal punctures and slashes up to 6mm.


  • Biodegradable sealing fibres and platelets
  • Friendly with CO2
  • Can seal holes as big as 6mm
  • Operating pressures range varies from 15 to 120 psi
  • Functions optimally between -20ºC to +50ºC
  • Seals porous tyres and bead/rim gaps

For the ultimate performance, pair this sealant with Peaty's Tubeless Rim Tape and Peaty's Tubeless Valves. Check out our clear set up instructions to ensure that you get the most from this product.

*Always check sealant levels frequently and top up as needed. If you struggle to form a seal, increase the dose of sealant in small increments.
