OKO Magic Milk™ is a step forward for latex-based free-flowing liquid tyre sealants. It is designed for ‘tubeless ready’ or full UST tubeless tyres (also usable in tubes: for maximum puncture proofing on UST and MTB tubes we recommend Puncture Free Bike or X-Treme)

The <Lo-Fat>™ tyre sealant, it is super-light, with a dose of 30-120ml per tyre in most road to mountain to downhill  bikes, depending on size.

Magic Milk™: the choice of leading World Cup contenders, Habitat Mountainbike Team. They are winning races using Magic Milk™ with Chaoyang tubeless-ready tyres on their Felt bikes and find it “perfect” – Maarten Kemperman, Team Manager. See the new video showing their technician applying the product at a race meeting.

Now also endorsed and used by David Rosa, 8-time Portugese MTB Champion, who has made his own Magic Milk video with a dramatic tyre spiking followed by a forest run! Also used by top road race teams.

The NS Bikes Factory Racing Team, a leading force in Downhill, has also switched from the traditional tubeless brand to Magic Milk (“your Milk is awesome!” – Dominic Tinner, Team Manager). And look how well the partnership is working, despite holes and gashes in their tyres!

1-2-3 for the team and for Magic Milk at Gstaad!

NOW with two types – both available in ALL the sizes:

TUBELESS in the white label for all-purpose MTB/XC use. Goes up against conventional natural latex products – and wins, hands down. Seals 6mm holes.

HI-FIBRE RACE in the black label – can be used in any tyre but is especially for added sealing power in low-pressure Downhill, Enduro, Gravel, Fat Bike applications: and at the top end, it deals with the high pressure of Road Race tubeless tyres, tubulars and tubes. Seals up to 7mm holes.

NEW 65ml ‘BackPack Pack’ mini-bottle – it will get you out of trouble out on the trail… Pack one or two along with a CO2 inflator, and you’re sorted…

250 ml bottle deals with up to two regular mountain bikes, or four racing bikes: for 26” MTB tyres it is just 60-80 ml per tyre.

500ml and 1 Litre bottles for multiple bike owners. Better value than any other known brand.

 5 Litre can for workshops and teams. Comes with a 60ml Injector for easy and accurate Presta or Schrader installation.

Simple Schrader fitting, using the valve core remover and filling tube supplied in every bottle cap: squeeze into am open tyre before fitting the second bead: or use an OKO Tyre Sealant Injector (especially when using removable-core Presta valves) for easy, accurate measuring.


Latex-based for sealing wheel/tyre bead imperfections
• Stickiest product there is: seals the sidewall porosity
Longer effective life than competitors – usually 6-9 months before you top up: will not ball up inside the tyre, dries as an even layer. Can be topped up so you don’t need to strip off the tyre.
Advanced synthetic latex formula – will not rot tyres or damage wheels and is safe for the many latex allergy sufferers
Contains corrosion inhibitors and does NOT give off ammonia
Washes off with water
Non Hazardous


Non Corrosive: Non Flammable: Non Hazardous (not excluded from air shipments unlike some ammonia-containing products). Washes out of the tyre if required.

NO ADVERSE AFFECT UPON TYRES OR RIMS (contains anti-corrosion agents).

WORKS WITH TUBELESS READY and FULL UST TUBELESS WHEELS/TYRES, with Schrader or removable-type Presta valves. (if you have non-removable Presta valve cores, pour Magic Milk™ into tyre well then mount tyre onto rim).

For ‘tubeless ready’ tyres on standard rims, always use a rim strip plus OKO Magic Milk™. Shake the tyre/wheel combination vigorously from side to side at each point to force the sealant into the little gaps between bead and rim, and into the tiny holes in the porous tubeless ready tyre sidewalls. Also spin the tyre on the wheel for a prolonged period. Follow tyre and wheel manufacturer instructions.

(For tyres with inner tubes, use OKO Puncture Free Bike or OKO X-Treme)
