Reserve’s sealant has been custom formulated to provide superior sealing for all tubeless tire systems. In laboratory and ride testing, it’s been found to provide a more durable seal, that will hold higher pressures on a bigger hole, for a longer period of time. The 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
