Muc-Off Road+Gravel Tubeless Tire Sealant

This specific formula is engineered for the higher pressures of road and gravel riding. While it will technically seal a tire, Muc-Off offers dedicated mountain bike sealants that are better optimized for the lower pressures and larger volume tires typical of MTB setups.

You should check and refresh the sealant every three to six months. This timeframe ensures the formula remains fluid enough to effectively seal punctures, especially if you live in a particularly hot or dry climate where evaporation happens faster.

No, the formula is non-toxic and ammonia-free, making it safe for use with carbon fiber rims and most common tire materials. It is designed to be non-corrosive, so it won't degrade your wheel components over time.

Yes, it remains effective in temperatures as low as -15°C. This makes it a reliable choice for winter training rides where other sealants might thicken or freeze.

While the sealant is robust, using CO2 cartridges can sometimes cause sealants to coagulate prematurely due to the rapid temperature drop. It is generally recommended to use a floor pump for initial setup and only use CO2 for emergency trailside repairs.

The formula is designed to seal punctures up to 7mm in diameter. This is quite generous for road and gravel tires, covering most debris you are likely to encounter on the road or trail.
