Product Information
Full details
The Challenge Smart Tubeless Sealant is an ideal solution for serious cyclists using vulcanised or handmade tubeless-ready tires who need reliable puncture protection without the corrosive drawbacks of traditional formulas. This ammonia-free, non-allergenic sealant effectively plugs cuts up to 6mm and resists coagulation even when using CO2 cartridges. While it offers impressive longevity, users should note that the 65ml bottle is designed for quick, precise applications, meaning it may be best suited for those performing regular maintenance rather than large-volume fleet servicing.

Extended Product Information
FAQs
Is this sealant compatible with all tires?
It is designed specifically for vulcanised and handmade TLR and Tubeless tires.
Will this damage carbon rims?
No, the ammonia-free formula is safe for carbon fiber and aluminum rims.
Can I use CO2 to inflate my tires with this sealant?
Yes, this sealant is specifically formulated to remain liquid and stable even when exposed to CO2.
How often should I add more sealant?
We recommend checking and potentially topping up the sealant every 6 months.
Does the bottle need to be shaken before use?
No, the Challenge Smart formula is ready to use immediately without shaking.
What is the maximum puncture size this can seal?
It is engineered to seal punctures and cuts up to 6mm in size.
Troubleshooting
Sealant leaking from the sidewall
Ensure the tire beads are seated correctly; if the leak persists, the cut may exceed 6mm and require a tire plug or patch.
Sealant is dry upon inspection
This is normal after 6 months. Clean out old residue and replenish with a fresh batch to restore puncture protection.
Valve core clogging during installation
Remove the valve core and clear the debris with a thin wire or pick before injecting the sealant.

Setup, Compatibility & Care
Installing Challenge Smart Tubeless Sealant is designed to be a clean process due to the direct-application bottle tip.
- Ensure the tire is properly seated on the rim.
- Deflate the tire fully.
- Remove the valve core using a core tool.
- Insert the application tip directly into the valve stem.
- Squeeze the required amount of sealant directly into the tire.
- Reinstall the valve core and inflate to the recommended pressure.
Since the formula does not require shaking, you can apply it immediately from the bottle. To maintain optimal performance, check the sealant level every 6 months. If you ride in particularly hot or dry climates, you may want to inspect the levels every 4 months to account for potential evaporation.
