Developed alongside World Cup mechanics and world champion racers. Peaty's Holeshot Tubeless Sealant is packed full of biodegradable fibers & sealing particles to give a fast and strong seal. Using the latest fast-acting latex, our water-based sealant is ammonia-free, non-hazardous and lasts up to 6 months in the tire in temperate climates. It won't ball up in the tire and is easily washed out. Our biodegradable fibers and particles bind together with the fast-acting latex to create a clot (like platelets in your blood) to seal holes or tears up to 6mm quickly and effectively.
