The Dynaplug Air Tubeless MTB Tyre Repair And Inflation Kit is the ultimate solution for mountain bikers who demand quick and effective tyre repairs on the trail. This all-in-one kit combines tyre repair and inflation, allowing you to fix punctures and reinflate your tyre without removing it or dealing with messy adhesives. Featuring a precision-machined air valve body and a stainless steel insertion tube, the Dynaplug Air ensures a fast, reliable, and clean repair that gets you back on your ride in seconds.
Designed specifically for tubeless tyres, this kit includes a unique viscoelastic impregnated rubber plug that bonds instantly and permanently to your tyre, maintaining sealant compatibility. The CO2 inflation system is cleverly integrated, enabling you to refill lost pressure immediately after plugging the hole. With its long MTB version insertion tube, the CO2 vents inside the tyre even through aggressive treads, making it suitable for 35c or smaller road tyres with the appropriate ROAD Air model.
Safety and convenience are paramount, so the kit comes with a storage pouch, soft nose plugs, and an air hose for valve stem inflation. Remember to follow the safety instructions carefully when handling CO2 cartridges, and consider practicing at home before heading out. Proudly made in the USA and backed by a lifetime warranty, Dynaplug Air combines cutting-edge technology with durability and ease of use for every mountain biker’s toolkit.
How quickly can I repair a puncture with the Dynaplug Air?
The repair process is extremely fast—simply remove the puncturing object, insert the plug with the tool, discharge CO2 to reinflate, and you’re ready to ride in seconds.
Is the repair plug compatible with tyre sealant?
Yes, the plug is made of a viscoelastic impregnated rubber designed to bond instantly and permanently while remaining sealant-friendly.
