Just two ounces of Stan's Tyre Sealant in a converted standard tyre or a tubeless tyre can repair up to a 1/4" hole instantly.
Pre-measured and ready to apply to one bicycle tyre.
Stan’s Tyre Sealant will stay liquid in a mountain bike tyre with a thin casing for two to seven months on average. Riding in arid climates or storing the bike in a hot area will require more frequent monitoring of sealant levels. Special anti-freeze agents allow the sealant to be used in environments as cold as -30° F.
