About Magic Milk Inner Tube Sealant
For MTB riders still running tubes, this is the formula that handles what tubes take the worst — snake bites, pinch flats, slits up to 7 mm. Water-based, lasts the life of the tube, CO2 compatible.
The same fibre technology that sealed AON Racing’s tubeless tyres — rebuilt for riders who run tubes. Innertube-Pro Hi-Fibre handles snake bites, slits, and punctures up to 7 mm. It’s CO2 compatible, works from −20°C to +50°C, and runs at the pressures DH and enduro riders actually use. The strongest innertube sealant in the Magic Milk line.
How it seals
The fibre-reinforced formula works the same way it does in the tubeless version: when air escapes, fibres rush to the breach, pack the hole, and bind into a durable seal — not a temporary patch. It doesn’t ball up inside your tube. It doesn’t migrate and dry out under hard riding.

- Why fibre-reinforced
Most innertube sealants are liquid patches — they fill a hole and hope the pressure doesn’t push them out. The fibres in this formula cross-link under pressure, turning the seal from a plug into a bond. It’s the difference between a tube that limps home and one that finishes the descent.
