Specialized 40mm Schrader Valve 29x1.9/2.3 Inch Inner Tube

Product Description

Specializeds standard inner tubes use a unique moulded method of construction to ensure a consistent thickness for enhanced riding quality & durability. Crafted from industry standard Butyl rubber, the Specialized Inner Tube offers excellent air retention to reduce the need for constant top ups while remaining light & thin to not hamper progress. A longer than normal 40mm Valve Stem is compatible with more rims than shorter 32mm valves & offers more purchase for your pump to hold onto without looking out of place.
