• Road Tires: Tubeless Sealant Fluid is specifically designed for use on road tires, offering effective protection against punctures and cracks.
• Different types of bikes: It is suitable for road bikes, gravel bikes, e-bikes, tubulars, inner tubes and scooters that use tubeless-compatible tires.
• Regular maintenance: It is recommended to check and replace all the sealant every 2 months to guarantee its effectiveness in preventing punctures. In the case of a visible puncture that has been sealed, half the recommended amount can be replaced.
• Shaking before use: Before applying the sealant, it is important to shake it properly to ensure a homogeneous distribution of the particles and to obtain the maximum performance.

1. Core Removal: Removes the core from the tire valve to allow the sealant to enter. Alternatively, break the tire bead to access the interior.
2. Sealant Application: Consult the measurement chart to determine the amount of sealant needed. Apply the sealant through the valve or directly to the inside of the tire. Be sure to follow the specific application instructions for each type of tire.
3. Refitting the tire: Reattach the core to the valve or bead the tire again, making sure it is seated correctly.
4. Maintenance: It is recommended to check and replace the entire amount of sealant every 2 months to ensure effectiveness against punctures. You can also fill in half the size after a visible puncture has healed.

MTB Formula sealant liquid for MTB tires is a product designed to provide an effective solution against punctures and cracks in mountain bike tires. With the ability to withstand pressures up to 3.5 bar (50.76 psi), this sealant is tubeless compatible and can be used on a wide range of tires including MTB, gravel, e-bike, fat bike, tubular, inner tube and skateboards.

• Efficient sealing: This sealant is capable of sealing punctures or cracks of up to 6mm in any tubeless-compatible mountain tire, providing minimal pressure loss from the moment of the puncture until it is completely sealed.
• Polyethylene nanoparticles: Thanks to the polyethylene nanoparticles in its composition, this sealant achieves a fast and effective seal, avoiding manual tire repairs.
• Easy cleaning: Its formula allows for easy cleaning of splashes, which makes it easy to maintain the tires and remove debris.
• Latex and Ammonia Free: This sealant is free of natural latex and ammonia, making it safe to use and compatible with a variety of materials.
• CO2 Compatible: Can be used in combination with CO2 inflation systems without compromising their effectiveness.
• Biodegradable: It is a biodegradable sealant, which makes it more friendly to the environment.

Tubeless MTB Tire Sealant is ideal for use in various applications such as:

• Mountain Bikes (MTB): Can be used on MTB tires of different widths, providing a reliable and long-lasting seal.
• Gravel: It is suitable for gravel bike tires, guaranteeing an effective seal even on rougher terrain.
• E-bike: Compatible with e-bike tires, ensuring additional protection in case of punctures.
• Fat-bike: This sealant is suitable for fat-bike tires, which have a greater width, offering a reliable seal in these conditions.
• Tubulars and inner tubes: It can also be used on tubulars and inner tubes, providing an effective solution against punctures.
• Scooters: Compatible with scooter tires, providing a safe and durable seal.

It is important to shake the product before use and follow the application instructions indicated in the sealant quantity table according to the type of roof. It is recommended to check and completely replace the sealant every 2 months to ensure its effectiveness or replace half the measure after a visible puncture has been sealed.

1. Disassembling the core: If the tire has a valve, remove the core to allow the sealant to enter. If there is no valve, break the tire to access the interior.
2. Sealant Application: Consult the measurement chart to determine the amount of sealant needed. Apply the sealant through the valve or directly to the inside of the tire. Be sure to follow the specific application instructions for each type of tire.
3. Refitting the tire: Reattach the core to the valve or bead the tire again, making sure it is seated correctly.

The rim tape for Tubeless systems is a product designed to achieve efficient sealing and perfect adhesion between the rim and the tire on bicycles with the Tubeless system. Made of a resistant, thin and malleable material, this rim tape is easily installed with just one turn of tape. Each roll contains 50 meters of tape, offering ample coverage for multiple installations.

After a correct installation, the rim tape provides a complete seal, guaranteeing that there are no air leaks between the rim and the tire. This type of rim tape is durable and will not peel or react when in contact with sealant fluids. In addition, it adapts perfectly to the shape of the rim, as long as the correct tape width is selected. Up to 5 tape width options are offered (22, 25, 27, 31, 35), allowing all existing rim widths to be covered, whether road, gravel, mountain or e-bike.

• Resistant and malleable material: The rim strip is made of a resistant but thin and malleable material, which makes it easy to install and guarantees its durability.
• Complete sealing: After a correct installation, a complete seal is achieved between the rim and the tire, avoiding air leaks.
• Compatibility with sealing liquids: The rim tape does not react or detach when it comes into contact with sealing liquids, ensuring an effective and long-lasting seal.
• Adaptability to different rim shapes: If the correct tape width is selected, the rim tape adapts perfectly to the shapes of the rim, guaranteeing optimal adhesion.
• Different Tape Widths Available: Up to 5 different types of tape widths are offered (22, 25, 27, 31, 35), covering a wide variety of existing rim widths on different types of bikes.

Tubeless rim tape is used in a variety of applications, including:

• Road bikes: Compatible with road rims, guaranteeing an effective seal in high pressure conditions.

• E-bike bicycles: Compatible with e-bike rims, ensuring additional protection and optimal sealing in conditions of intensive use.

It is important to follow the recommended directions for use, cleaning the rim and surface before applying the tape, and maintaining high tension during installation to ensure proper adhesion.

1. Cleaning: Clean the rim and the surface where the tape is to be attached using isopropyl alcohol or a similar product to ensure a clean and residue-free surface.
2. Tape Installation: Begin by taping approximately 15cm of tape to the rim, then stretch the tape while making a full turn around the rim. Add an additional 2-4 inches of tape and glue it over the first loop. It is important to keep the tape taut during installation so that it can properly conform to the shapes of the rim and achieve better grip.
3. Rounding off the corners: At the end of the installation, use a pair of scissors to round off the corners on the tail end of the tape. This helps prevent premature shedding and improves durability.
