About Magic Milk Sealant
AON Racing run it. SCOTT-SRAM switched to it after Nino Schurter spent a year testing both.
Tubeless-Pro Hi-Fibre is ammonia-free synthetic latex with quick-seal fibres — it handles pressures from 15 psi on a DH run to 120 psi on the road, seals punctures up to 8 mm, and stays liquid for 6+ months without balling up.
- Tested in Downhill, Enduro, MTB, road and gravel
- Synthetic latex — no ammonia, non-allergenic
- Fibres stay in suspension — no balling up, just top up and ride
- Compatible with CO2 and foam inserts
- Safe for tyres and rims
- Seals up to 8 mm punctures
Most tubeless sealants patch small holes and hope. Tubeless-Pro Hi-Fibre seals punctures up to 8 mm — in seconds, at any pressure, in any temperature a trail throws at you. It’s what AON Racing runs. It’s what replaced the previous sealant at SCOTT-SRAM after a year of side-by-side testing. 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.

- Why synthetic latex
Most tubeless tyre sealants are built on natural latex — which means rubber trees, which means rainforest. Magic Milk uses synthetic latex instead. Same sealing performance. No deforestation. Washes off with water.
