Airolube Offroad Flat Guard Tubeless Sealant – 500ml

Airolube Offroad Flat Guard: Tubeless Sealant for Mountainbike and Gravel

Off-road terrain brings coarser tread patterns, sharp rocks and rough surfaces that leave your tubeless tires far more exposed to punctures than on the road. Airolube Offroad Flat Guard is specifically formulated to handle this higher flat risk, sealing punctures fast so you can keep riding without losing pressure or momentum. Unlike most sealants that rely on microplastics, this formula uses lightweight cork particles that are large enough to plug even a substantial cut in the tread in one go, yet light enough to avoid increasing rolling resistance. Best for mountainbike and gravel riders who need reliable puncture protection on demanding, technical trails.

How do I apply Offroad Flat Guard to my tire?

Shake the bottle well before use. Remove the valve core and inject the sealant through the valve using an injector, or pour it directly into the tire before mounting. Reinstall the valve core, inflate the tire, and spin the wheel a few times so the sealant spreads evenly across the tread.

What makes this sealant different from other tubeless sealants?

Most sealants rely on microplastics to close punctures. Offroad Flat Guard instead uses lightweight cork particles, which are large enough to seal even a significant tread cut in one go, while staying light enough not to increase rolling resistance during your ride.

Is Offroad Flat Guard suitable for road bikes too?

Offroad Flat Guard is developed for mountainbike and gravel use, where terrain is rougher and punctures tend to be larger. For road bikes, where weight matters most and punctures are typically smaller, Airolube’s Racing Flat Guard is the better-suited alternative.
