Tubeless Sealant designed for Road and Gravel. This high-performance sealant keeps you pumped for whatever the road or trail throws at you. Formulated from advanced synthetic latex and a matrix of biodegradable sealing particles, it seals holes up to 7mm. Plus, it’s completely non-toxic and allergy-free, so your only worry will be smashing that KOM. Application is as simple as squeezing it through your Presta valve or adding it straight into the tire, and thanks to Muc-Off’s advanced polymer technology, the sealant bonds to the inside tire wall like a suit of armor, ready for battle the second a puncture strikes.
