Bike users told us that there was a gap in the market. Many riders have discovered the need for a bike tyre sealant, but conventional latex-based bike sealants dry out rapidly and need to be replaced.

After years of development and testing, OKO introduced a ground-breaking range of Bike sealant products at Eurobike in 2010, and launched in Asia at the Spring 2012 Taiwan show. At every Eurobike since then, OKO has moved bike sealant performance to a whole new level, with three new or enhanced formulations:

OKO Puncture Free Bike (all-purpose) and OKO X-Treme Dirt Bike (for off-road tube use) are now lighter and smoother than ever, and represent an advance in puncture sealing performance compared to any competitor. Both last the life of the tyre. They are perfect for tubes (and for full UST tubeless: for all other tubeless set-ups, use Magic Milk).

OKO Magic Milk™ comes in two varieties, Tubeless for regular MTB users; and premium Hi-Fibre for race teams no matter what the tyre pressure they run – in tubeless downhill, MTB and road racing tyres. It’s the new gold standard in tubeless tyre sealants: lightweight and synthetic latex-based so it is ammonia free, allergy-free and rim & tyre friendly. Now chosen by the World’s best teams.

Worldwide testing in all temperatures and terrain confirms that OKO out-performs all other products.

NEW: OKO Magic Plug! A brilliant kit to get tubeless riders out of trouble in the middle of nowhere, when even the best sealant (i.e. Magic Milk) can’t seal a nasty gash in the tyre. Lightweight and strong, with two sizes of plug, it’s a must-have item…

The OKO Tyre Sealant Injector is a syringe device that can cleanly and accurately dispense sealant (or other liquids), plus it contains a double screw fitting for both Presta and Schrader valves. It has a unique, large 150ml capacity per filling.
