But is it pink?

Muc-Off, the company best known for its extensive range of cleaning products, has decided to enter the tubeless sealant market with the launch today of its No Puncture Hassle Tubeless Sealant Kit. Who saw that one coming?

- What are the pros and cons of tubeless tyres?

Tubeless wheels and tyres are growing in popularity, with more choice and greater understanding of the benefits and the practical side of installing tubeless tyres. A key component of a tubeless setup is the sealant which replaces the inner tube and in many cases can seal small holes caused by flint, glass or thorns that manage to slice through the tyre. This puncture prevention is the biggest appeal of a tubeless setup.

Muc-Off makes some impressive claims for its new No Puncture Hassle Tubeless Sealant Kit. It boldly tells us it has used “cutting-edge microfibre molecules” that are able to fill large holes in the tyre, up to 6mm in size. It ’s biodegradable, non-corrosive and easy to wash off with warm water.

It also claims the sealant lasts six months before it needs topping up, it won’t dry out or ball up and is compatible with CO2 canisters.

The British company says it has developed the new sealant in collaboration with some of the world’s top downhill and pro-peloton and it’s compatible with tubeless-ready and UST wheels and tyres.

Installation is said to be easy, the 140ml pouch is designed to fit straight onto Presta valves (with the valve cores removed) to avoid making a mess. You can also pour it straight into the tyre before you fit the tyre to the rim.

Muc-Off has also developed a rather novel UV detection system that can highlight punctures in the tyre that the cyclist might not have spotted.

“We have tested ‘No Puncture Hassle’ under the most brutal conditions on the planet with 3 years of deep R&D using a wide group of our pro athletes from around the world. The formula we finally created is a result of 100s of hours of testing, the results of which have taken tyre sealant performance to a new level,” explained Alex Trimnell, Muc-Off Managing Director.

“The feedback we’ve had from our professional riders has been awesome! We are really excited to have created one formula which works to the highest performance in all tubeless tyres, from Pro Road Racing to World Cup Downhill and everything in between. Oh and lastly, we really don’t like single-use plastics so would encourage all to use our 1-litre refill to fill up the pouches.”

A 140ml kit costs £9.99 with 1-litre refill £29.99 and a 5-litre workshop kit costing £120.
