Muc-Off Road and Gravel Tubeless Sealant 1L

Season:2024

Brand:Muc-Off

Code:21042

High-Performance Road, Gravel & CX Tubeless Tyre Sealant

The Muc-Off Road & Gravel Tubeless Sealant is a premium high-pressure tubeless tyre sealant engineered specifically for road cycling, gravel riding, and cyclocross (CX). Designed to perform under fast-paced conditions and mixed terrain, this advanced synthetic latex sealant delivers rapid puncture sealing, long-lasting protection, and high-pressure compatibility up to 110psi.

Formulated using water-based synthetic latex and a matrix of biodegradable mineral flakes and bamboo fibre particles, this innovative tubeless sealant seals holes up to 7mm quickly and effectively. The fast-acting sealing particles plug larger cuts, while advanced polymer technology bonds the sealant to the inner tyre wall, forming a protective coating that’s ready to respond instantly when punctures occur.


Optimised for High-Pressure Road & Gravel Tyres

Unlike standard MTB sealants, this road-optimised formula is designed to remain free-flowing at higher pressures while maintaining excellent sealing performance. It works from low gravel pressures right up to 110psi, making it ideal for:

  • Road tubeless tyres
  • Gravel and adventure bikes
  • Cyclocross race setups

The ammonia-free, zero natural latex formula is completely non-toxic and allergy-free, offering improved safety during installation and maintenance. It also won’t freeze in temperatures down to -15°C and remains effective in a wide range of riding conditions.


Easy Installation & CO₂ Compatible

Application is quick and simple:

  • Inject directly through a Presta valve stem
  • Or pour straight into the tyre before seating

The formula is CO₂ compatible, ensuring quick roadside inflation when needed.

Sealant lasts 3–6 months depending on climate and riding conditions. Regular inspection and top-ups are recommended, particularly in hot, dry climates above 35°C or approximately every 750 miles.

WARNINGS

  • Keep out of reach of children.
  • Dispose of content/container in accordance with local regulations.
  • Avoid contact with eyes.
  • Do not drink.

HOW TO:

  1. Shake pouch vigorously before use, now turn pouch over to check particles are mixed. Put your bike in a work stand if possible. Remove the core of your Presta valve (if you have non-removable valve cores, simply pour directly into your unseated tyre and remount).
  2. Ensure pouch is thoroughly shaken right before filling. 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. 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.
  3. Repeatedly spin the wheel, shake it from side to side and hey presto, you’re now ready to rock ‘n’ roll! Regularly check the amount in each tyre and simply top up as needed.
  4. Before adding the Muc-Off sealant into your tyre, make sure any other sealant has been thoroughly removed before hand. If you get sealant on your frame, parts or clothing remove as quickly as possible with clean water and a cloth. Try not to let the sealant dry before you can wash your kit properly at home.

KEY TIP! Ask Siri/Meta/Google or Alexa to add a reminder to your phone to check your tyres and sealant in 3-6 months. *If using in hot conditions (+35°C) simply top up if needed and check every couple of months.


When filling sealant into brand-new tyres, Muc-Off recommend degreasing the inside surface of the tyre to remove any oils or mould-release agents/residues from when the tyre was manufactured. For the best results use the Muc-Off Quick Drying Degreaser, Disc Brake Cleaner or Glue and Sealant Remover, along with a clean cloth for effective cleaning. This process ensures maximum adhesion and effectiveness of the sealant.


HOW MUCH SEALANT DO I NEED?

Minimum amount per tyre: (add up to 20ml extra for increased protection)

Road Tyres

  • 23c, 25c = 40ml-50ml
  • 28c = 50ml-60ml

Gravel Tyres

  • 30c - 45c = 70 - 80ml

Keep out of reach of children. Dispose of content/container in accordance with local regulations. Avoid contact with eyes. Do not drink.

PLEASE REFILL THIS POUCH USING THE MUC-OFF 1 LITRE REFILL – Refilling is WAY better than recycling! **Muc-Off recommend the CO2 is applied from the top of the wheel/tyre so that it is not injected directly into the sealant at the bottom.
