A compact all-in-one tubeless tire repair kit and CO2 inflator makes quick work of repairing punctures on the road or trail. The CO2 inflator head fits both Presta and Schrader valves and takes a single threaded 16g or 25g CO2 cartridge. The tire reamer, serrated knife and plug insertion tools fold into the body of the tool, while a special hidden compartment holds the repair plugs. A mounting module allows the Tubi Master+ to be attached to seatposts or bike frames with the included strap.
