After performing the unpleasant task of dismounting your deflated tube-type tire, you can patch the tube with these six feather edge cold patches that self vulcanize from friction heat and rubber cement. You need not dismount your tubeless tire as this kit includes five reinforced rubber string plugs for an 'on the wheel' repair using the split-eye needle insertion tool. This brand new kit comes in a heavy-duty zippered canvas bag that measures 7" in diameter x 1 1/4" thick and weighs only 14 oz. - It features the Engine-Air Pump with a longer 5 foot hose and quick release lever (size does matter). (See Inflation Devices) Motorcycles with easy access to their spark plugs can utilize this unit for an unlimited supply of clean outside air. It works on twins and multi-cylinder engines.
