Q: How do you fix a tubeless mountain bike puncture?
A: A tubeless puncture is usually fixed by letting the tyre sealant close the hole or using a tyre plug (like Dynaplug) if the puncture is too large. If sealant does not seal it, a plug is inserted into the hole to block air loss, then the tyre is reinflated to continue riding.

Q: Why is my tubeless tyre not sealing?
A: A tubeless tyre may not seal if the puncture is too large for sealant, there is not enough sealant in the tyre, or the tyre bead is not seated correctly on the rim. If the puncture is too big for the sealant to work, you can use a tyre plug like Dynaplug.

Q: When should you use a tyre plug vs sealant?
A: Sealant is used for small punctures and slow air leaks that close automatically while riding. A tyre plug like Dynaplug is used when the hole is too large for sealant alone to seal.

Q: Can you ride a tubeless tyre after a puncture?
A: Yes, you can often continue riding after a puncture if sealant or a plug successfully seals the hole. If the tyre holds pressure, it is usually safe to ride, although pressure should be monitored to make sure the repair stays stable.
