Our sealant has been custom-formulated to provide superior sealing for all tubeless tire systems, from road to MTB. In both our lab and real-world testing, weve found it to deliver a much more durable seal when compared to its competitors. What do we mean by more durable? Well, it will hold higher pressures on bigger holes for longer periods of timeensuring youre not limping home with 10 psi left or succumb to a second blow-out after the holes been sealed. A 200ml bottle provides enough sealant for two mountain bike wheels and four road bike wheels.
