We’ve got lots of bikes - a beach cruiser, a 29er, a road bike - and we never seem to have a spare tube with the right valve. We usually have a a presta inner tube when we need a Schraeder, or a Schraeder when we need a presta valve. The solution - stock up on the bike tube you need. We offer top-quality tubes from Continental and Michelin, both latex and butyl tube.
