How big of a puncture can OKO Hi-Fibre seal?

Thanks to its highly advanced structural microfiber matrix and suspended blue granules, OKO Magic Milk Hi-Fibre Race Sealant can instantly and permanently seal tread punctures and casing gashes up to a massive 7mm.

Can you use OKO Hi-Fibre sealant in road tubeless tires?

Yes, absolutely. Unlike standard mountain bike sealants that fail under road pressures, the Hi-Fibre Race formula is specifically engineered to hold its seal under high road pressures up to 120 PSI.

Sovereign Race Defense: Advanced Microfiber Matrix Meets Multi-Pressure Adaptability, 7mm Puncture Plugging Power, and World Cup-Proven Synthetic Latex Efficiency

Protect your race runs from catastrophic pressure losses, seal high-pressure road casing punctures instantly, and charge through rock gardens with the absolute tire security trusted by World Cup champions. OKO Magic Milk Hi-Fibre Race Sealant (1 Liter) represents the absolute pinnacle of high-velocity competitive puncture prevention—specifically engineered to handle the extreme high-pressures of road racing as well as the ultra-low pressures of downhill, enduro, and gravel events. Sourcing specialized racing chemicals independently from international online warehouses often exposes you to frustrating shipping delays, single-item courier minimums, or unexpected port clearance hold-ups at the border. Epic Sports handles all international logistics natively, straight to Nairobi. Formulated with a dense network of microfibers and larger blue sealing granules, this premium 1-liter workshop bottle guarantees a permanent, airtight race seal block after block.

Why the OKO Hi-Fibre Matrix Governs the Race Run:

Proprietary High-Density Microfiber Matrix: Extreme puncture healing. Infused with a specialized web of microfibers and blue granules that rapidly knit together, sealing tread punctures and sidewall gashes up to a massive 7mm in seconds.
Multi-Pressure Adaptability Engineering: Versatility under stress. Specially formulated to seal punctures under high road pressures (up to 120 PSI) without spraying out, while performing flawlessly in low-pressure downhill and cyclocross setups.
Zero-Shake Suspended Particle Tech: Instant readiness. Built on an advanced synthetic latex base where the sealing fibers stay permanently suspended in solution, eliminating the need to vigorously shake the bottle before application.
100% CO2 and Foam Insert Friendly: Hassle-free race-day recoveries. Won't coagulate, freeze, or curdle when hit with freezing gas from CO2 emergency inflators, and is completely compatible with premium foam rim inserts (like CushCore).
World Cup Team Proven Pedigree: Selected and raced by the absolute best. Trusted and run daily by elite teams worldwide, including the SCOTT-SRAM MTB Racing Team (featuring world champions Nino Schurter and Kate Courtney).

Frequently Asked Questions (FAQ) for Competitive Cyclists:

How does the "Hi-Fibre" Race formula differ from the standard OKO Magic Milk sealant?

This is a crucial technical distinction built for competitive environments. The standard OKO Magic Milk is an exceptional, free-flowing sealant designed for daily trail riding and training, sealing holes up to 6mm. The Hi-Fibre Race sealant is a heavily loaded, high-performance upgrade. It features a denser, stickier synthetic latex base packed with structured microfibers and larger blue granules. This allows it to physically plug larger cuts (up to 7mm) much faster, and hold its seal under the extreme high pressures of road racing tires where standard sealants would simply spray out of the puncture.

Does the 1-Liter bottle feature an applicator cap?

The 1-Liter bottle is designed primarily as a high-value workshop reserve for mechanics and multi-bike households. For the cleanest, most precise installation, we recommend pouring the fluid directly into a tire casing before seating the bead, or using a dedicated sealant injector syringe to feed it through a removable Presta valve stem. If you are looking for a highly portable, quick-inject bottle to keep in your race toolbox or gear pack, our OKO Hi-Fibre 250ml size features an integrated tapered Presta-valve applicator cap.
