The Vittoria Pit Stop Magnum is the leading repair and inflation cartridge designed for MTB sizes (26" up to 2.30 – 27.5" up to 2.20 – 29" up to 2.10). Ideal for larger-volume tires, it's convenient to carry on your bike during MTB events. Pit Stop Magnum swiftly gets you back in the race with its efficient repair capabilities. Compatible with butyl tubes, latex tubes, and tubeless tyres, this foam solution is lightweight, easy to use, and cleaner than traditional liquids. It fits both Presta and Schrader valves, and can also be used preventively to avoid flats by pre-loading a new tire. Tubes and tyres remain usable after application.
