When it comes to ride quality and speed, it's hard to best tubulars. However, they leave little to be desired in the reliability department. In fact, flats are something that are all too common on low profile road tires which is why Orange Seal provides the Road Tube Kit. Orange Seal's Road Kit includes two 48mm 700 18x23mm tubes with removable core Presta valves, an injection system, core removal tool, and a 4oz bottle of sealant. This allows you to add 2 ounces of Orange Seal to each tube eliminating most punctures. It also enhances air retention so you'll spend less time topping off tires and more time riding at optimum pressure. Orange Seal's Road Tube Kit adds negligible weight to your ride, making it perfect for a set of training wheels and commuter bikes.
