How to Fold a Cycling Tube

The common bicycle tire contains an internal rubber tube. The inner tube gives the tire definition, while providing a measure of cushion for the rider. Flats generally occur whenever a sharp object, such as a nail, penetrates the tire casing and punctures the inner tube. Keeping a spare tube on hand prepares the rider for these occasional misfortunes. Convenient storage of the inner tube requires first folding it into a compact and secure shape.

Instructions

    • 1

      Lay the cycling tube flat on a smooth patch of ground or tabletop. Avoid any surface that might abrade or puncture the tube.

    • 2

      Remove the valve cap. If the tube contains a Presta valve, unscrew the locknut from the tip of the valve. This type of valve, typically found on performance-oriented bikes, contains an inner stem that threads in and out.

    • 3

      Place the tip of your thumbnail against the stem at the center of the valve, and push down. Pushing the stem down opens the valve, allowing air to escape.

    • 4

      Force the air inside the tube forward and out through the valve using your other hand.

    • 5

      Fold the tube evenly toward the stem. While rolling the tube, depress the valve stem as needed to free any trapped air.

    • 6

      Replace the valve cap, and wrap a rubber band tightly around the center of the tube. The rubber band prevents the tube from unfolding.
