When it comes to reliable tyre sealants, OKO has been a trusted name for decades. For nearly 50 years, the UK-based company has been developing sealing solutions for applications where downtime simply isn’t an option - originally in industrial use and mining. Around 15 years ago, OKO expanded into the cycling world. Now, following a comprehensive rebranding, OKO has become Magic Milk as its dedicated brand for tubeless mountain bike sealants in a fresh, modern look - while raising the bar technically once again.
As a long-time distributor and R&D partner, we’ve been closely involved with OKO for many years. We know these products not just from brochures, but from real-world use and shared development work. That makes this latest evolution especially meaningful to us.
Even Stronger, Even More Versatile
In the current relaunch, Magic Milk has refined the Hi-Fibre formula once again. The result: the latest Magic Milk Hi-Fibre can now seal tyre damage of up to 8 mm. According to the manufacturer, it works reliably at pressures from 15 to 120 psi and in temperatures ranging from -20 °C to +50 °C - making it a true all-rounder for all types of cycling, from gravel & road to downhill.
Another key benefit is that the sealant is non-corrosive. It does not attack valves, rims, spokes, or aluminium nipples, and any residue can be easily washed away with water - protecting both the bike and the rider’s peace of mind.
New Design, Improved Handling
The rebranding goes beyond visuals. The packaging has also been redesigned. Smaller bottles now feature a practical click-cap that integrates both a valve core tool and a pull-out filling hose, making clean and easy application even simpler. For professional workshops, Magic Milk continues to offer large-volume containers, while cyclists can choose between 250 ml, 500 ml, and 1000 ml bottles. A newly designed bottle head further improves pouring and dosing.
Conclusion
With its updated look and further enhanced formula, Magic Milk firmly establishes itself as OKO’s dedicated brand for the bike industry. From our perspective as a long-standing distributor and R&D partner, it’s clear: this rebrand is far more than a cosmetic update - it’s the next logical step in a success story built on experience, innovation, and real-world performance.
