      • Before races or long trips - check and top up sealant before important rides.

      How does OC1 Tubeless Sealant work?

      OC1 Tubeless Sealant works by coating the inside of the tire with a protective liquid layer. When a sharp object punctures the tire, air pressure pushes the sealant into the hole. The liquid reacts with air, thickens quickly and helps close the puncture.

      The synthetic latex formula creates a durable seal for most small punctures, helping you continue riding without removing the wheel or installing a tube. The sealant is friendly to common bicycle materials, including tires, rims and valves, and can be topped up through the valve or added when the tire is removed.

      How to use OC1 Tubeless Sealant - step by step guide

      1. Prepare tire and rim

      Ensure the tubeless tire is properly seated on the rim and the rim tape is correctly installed. When installing a new tubeless setup, always check system airtightness before adding tubeless sealant.

      2. Remove valve core

      Use a valve core tool to unscrew the core from the tubeless valve. This allows the sealant for tubeless tires to flow easily into the tire. Keep the valve core in a safe place.

      3. Add the correct amount of tubeless sealant

      Inject the sealant using a syringe or pour directly from the bottle through the valve.

      • Road tires: 60-80 ml
      • Gravel / MTB: 80-120 ml
      • 29" / Plus tires: up to 120-140 ml

      Using the correct amount of tubeless tire sealant ensures optimal puncture protection without unnecessary weight.

      4. Reinstall valve core

      Screw the valve core back into the tubeless valve and tighten securely. Avoid over-tightening to prevent damage.

      5. Inflate tire to recommended pressure

      Inflate the tire using a pump, compressor or CO2 cartridge. Follow manufacturer recommendations - typically from 15 PSI (MTB, gravel, enduro) up to 80 PSI (road bikes). OC1 Tubeless Sealant is fully CO2 compatible.

      6. Distribute the sealant evenly

      Rotate and shake the wheel in multiple directions to spread the sealant across the entire tire interior. A short ride helps ensure even coverage and maximum sealing performance.

      Important tips when using tubeless sealant

      Temperature conditions - apply sealant at moderate temperatures. Avoid using on hot tires immediately after riding. Best results are achieved at room temperature.

      Shake before use - shake the bottle for 10-15 seconds to mix the formula properly.

      Check sealant regularly - inspect every 2-3 months. If the sealant dries out or forms clumps, refill or replace it.

      Protect clothing - tubeless sealant may stain fabrics. Use gloves or wear appropriate clothing during application.

      Pro tips for longer tire life

      Regular maintenance - check tire pressure and sealant condition every 1-2 months. Faster air loss or visible residue means it is time to top up.

      Seasonal check - after winter storage, always refresh the tubeless tire sealant before starting the riding season.

      OC1 Tubeless Sealant FAQ - common questions

      Does OC1 Tubeless Sealant work with every bicycle type?

      Yes, OC1 Tubeless Sealant is a universal tubeless tire sealant that works with high-pressure road bikes (up to 80 PSI) and low-pressure MTB, gravel, enduro and downhill bikes (from 15 PSI). One formula is suitable for all tubeless systems.

      How much tubeless sealant do I need per tire?

      The recommended amount of tubeless tire sealant depends on tire size:

      • Road tires: 60-80 ml
      • Gravel / MTB: 80-120 ml
      • 29" / Plus tires: 120-140 ml

      Using the correct amount ensures optimal puncture protection and performance.

      How long does tubeless sealant last in a tire?

      OC1 Tubeless Sealant provides up to 6+ months of protection in moderate climates. In hot or dry conditions, check and top up every 3-4 months. Regular inspection is recommended for best performance.

      Will tubeless sealant damage tires or rims?

      No, this tubeless sealant is safe for all common bicycle materials, including rubber, carbon and aluminum. It does not cause corrosion and will not damage tires, rims, rim tape or valves.

      Can I use CO2 cartridges with tubeless sealant?

      Yes, OC1 Tubeless Sealant is fully compatible with CO2 cartridges and maintains its sealing performance.

      What should I do if the sealant dries or clumps?

      Clumping means the tubeless sealant is drying out. Add fresh sealant or replace it completely. Temporary shaking may help, but refilling is recommended.

      Does tubeless sealant fix all punctures?

      It effectively seals small punctures caused by thorns, glass or small nails up to approximately 3-4 mm. Larger holes may require a tubeless plug or tire replacement.

      How should I store tubeless sealant?

      Store between 5°C and 25°C in a dry place away from direct sunlight. Keep the bottle tightly closed and shake before use to maintain optimal performance.

      Can I mix OC1 sealant with other brands?

      Mixing different tubeless tire sealants is not recommended, as formulas may react unpredictably. For best results, remove old sealant and use fresh OC1 only.

      Does tubeless sealant add weight to the bike?

      The sealant has a density similar to water. Typical usage adds around 60-120 g per tire, which is minimal compared to the benefit of reliable puncture protection.

      Can I use tubeless sealant with inner tubes?

      No, tubeless sealant is designed specifically for tubeless systems and does not work effectively with inner tubes.

      Is tubeless sealant easy to clean?

      Yes, dried residue can be cleaned with warm water and a sponge. It does not permanently damage most surfaces when cleaned promptly.
