Most tubeless sealants patch small holes and hope. Tubeless-Pro Hi-Fibre seals punctures up to 8 mm instantly. It's what AON Racing runs. SCOTT-SRAM's head mechanic, Yanick Gyger, tested it in South Africa's heat and thorns, then put it in his riders' tyres, Nino Schurter's included. It's tyre sealant's best kept secret.

How it seals

The formula is synthetic latex with quick-seal fibres held in suspension. When a puncture opens and air rushes out, the fibres pack the hole and bind fast — not a temporary plug, a durable seal. It doesn't ball up. It doesn't dry out under hard braking or sharp cornering. It holds.
