About the Muc-Off Tubeless Kit XC/Trail The Muc-Off Ultimate Tubeless Kit contains everything needed to get a tubeless-ready wheelset set up and ready to roll. Each Kit contains a Muc-Off Tubeless Rim Tape, Seal Patches, 2 CNC-machined black tubeless Valves and 2 pouches of No Puncture Hassle Tubeless Sealant. The cutting-edge molecules fill the bigger holes and tears, whilst the advanced latex forms a strong seal instantly. The Muc Off formula also contains a unique UV detection system that highlights any punctures you haven’t seen during your ride. Developed with the world's top downhillers and pro peloton teams, to give you the finest tyre sealant available. It's non-corrosive and easily washes off with water. Compatible with tubeless ready and full UST wheels/tyres, No Puncture Hassle works from 15psi-120psi and temperatures from -20°C to +50°C. Our pouch is designed to fit your Presta valve perfectly and is ideal to add to your toolkit or ride pack for emergency top ups on the go! Directions for use 1. Shake pouch vigorously before use. 2. Put your bike in a work stand if possible. 3. Remove the core of your Presta valve with the tool provided (if you have non-removable valve cores, simply pour or use the scoop to apply directly into your unseated tyre and remount). 4. With the valve at the 12 o’clock position, and using the non-drive side of the bike, push the pouch over the valve and rotate the valve to the 6 o’clock position. 5. Squeeze in the desired amount and fold the pouch to the desired fill line, re-insert the valve core and inflate the tyre in accordance with your manufacturer’s recommendations. 6. Repeatedly spin the wheel, shake it from side to side and hey presto, you’re now ready to rock ‘n’ roll! After use, the valve core removal tool can be added to your valve so it’s always there when you need it! 7. Regularly check the amount in each tyre and simply top up as needed. Keep out of reach of children. Dispose of contents/ container in accordance with local regulations. 8. Avoid contact with eyes. Do not drink. About Muc-Off At Muc-Off we’re big into being active. Whether it’s on a mountain, trail or at the skate park, we just love to be outside and going big. We’re obsessed with making the most innovative care products around to keep you and your toys running at their maximum and making them look like new when you’re done! So what’s the story? It all started way back when Right Said Fred were too sexy for their shirts and Downhill wasn’t even part of the World Cup. Yep, way back in 1991 Rex and Marilyn Trimnell got things started with X-Lite UK. After designing and manufacturing the world’s first twin crown bicycle fork, Rex created a perfectly pink spray to clean his kit. To make a long story short, Rex’s cleaner was the best thing since sliced bread, and it wasn’t long before word got out and Muc-Off was born.Looking for alternatives to stores like JD Sports, eBay, SHEIN, ASOS, Next, Best Choice UK, Very, Decathlon UK, Argos, schuh, Temu, BuyBetter, or Nike Official?
