Product Description

Ride with confidence — make punctures a memoryYou want to ride hard and keep going. No Puncture Hassle Tubeless Sealant lets you do that. It seals holes and tears fast, so you keep momentum, feel more in control and waste less trail time fixing flats. It’s light in the bike bag and heavy on performance.Why it mattersA sealant that actually stops punctures changes the ride. You hear fewer hisses. You lose less air. You don’t spend the best part of a day hunting for a slow leak. This one works across downhill, enduro and MTB setups, and it includes a UV dye to show you any hidden damage after the ride.How it works — simply and reliablyThe formula uses latex plus larger molecules to fill bigger holes and tears instantly. That combination seals porous tyres, bead and rim gaps, and bites into holes up to 6 mm. It won’t ball up in the tyre and it’s non-corrosive. Rinse off with water when you’re done. The pouch fits Presta valves for quick top-ups on the trail.Fit, pressure and temperature rangeCompatible with tubeless-ready and full UST wheels/tyres.Works from 15 psi to 80 psi.Effective between -20°C and +50°C.In very hot conditions (+35°C), a top-up may be needed.How to fit the sealant (quick guide)Remove old rim tape and clean the rim. Let it dry.Fit new tape from the opposite side of the valve. Press it down firmly as you go. Overlap the tape by 10–15 cm. Leave a little unstuck to trim, then press down to seal. Check for air pockets with your thumb.Pierce the tape at the valve hole with a pin. Insert the valve with the correct rubber fitment. Refit the O-ring and lock ring—don’t overtighten.Mount the tyre carefully. Inflate until the bead seats (you should hear popping).Release the air and remove the valve core. Shake the pouch, screw it onto the valve upright, then invert the wheel and squeeze the sealant in by rolling the pouch.Refit the valve core and inflate to your desired pressure.Tip: For new tyres, degrease the inside to remove mould-release oils for the best seal. We recommend Quick Drying Degreaser, Disc Brake Cleaner or Glue and Sealant Remover plus a clean cloth.How much to use (minimum per tyre)26" MTB & 27.5": 60–75 ml (4–5 scoops)Cross 700c: 60–75 ml (4–5 scoops)29" MTB: 105–140 ml (7 or the whole pouch)Downhill: 120–140 ml (8 or the whole pouch)(Add up to 30 ml per tyre for extra protection)Key Features:Seals tears and holes up to 6 mmSeals porous tyres and bead/rim gapsLasts up to 6+ months in temperate climates* and won’t ball upContains larger molecules to fill big holes and tearsUnique UV detection system to highlight unseen puncturesNon-corrosive and easy to wash off with waterAmmonia freeCO2 compatiblePouch fits Presta valves for trail top-upsWorks across MTB, enduro and downhill setups*If using in extreme heat (+35°C), simply top up if needed.Project GreenThis product carries a Project Green credential.
