Lightweight, practical, disposable single use cartridge The foam remains liquid inside the tyre for 3 months (more if the environmental conditions are good) Pit Stop Magnum 75ml (26” up to 2.30 – 27.5” up to 2.20 – 29” up to 2.10) is the market-leading repair and inflation cartridge in MTB size. Specifically designed to repair bigger volume tires, it is easy to carry on the bike during all types of MTB events. Pitstop Magnum is made to get you back in the race without delay. Works on butyl tubes, latex tubes as well as tubeless tyres. This foam is light, easy to use and cleaner than dealing with liquids. It will fit both Presta and Schrader valves. Alternatively, you can use the Pit Stop to pre-empt flats by loading a new tyre. Tubes and tyres can continue to be used after application.
