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, we’ve 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 time—ensuring you’re not limping home with 10 psi left or succumb to a second blow-out after the hole’s been sealed. A 200ml bottle provides enough sealant for two mountain bike wheels and four road bike wheels. Features Fills holes up to 7mm. Biodegradable natural fiber. Compatible with all tire types, both high- and low-pressure. No Hassles 200ml and 500ml options. Free shipping and returns for US customers. Sealant Material Safety Document
