This sealant has been developed specifically with Rene Herse tires in mind. Setting up tires tubeless has never been easier – the sealant is designed to seal the casing and the bead against the rim. It is low in allergens and cleans up easily. On the road, it seals small punctures. The sealant is fully biodegradable and does not pose any risk to the environment in case of a spill on road or trail. 500 ml (17 oz) bottle is enough for 4-6 tubeless installations. Made in Japan.
