The Specialized SV Tube TR 20 × 1.5–2.2 (32 mm) is a butyl-rubber inner tube engineered with a dual-wall construction that places a thicker outer layer against the tire casing for enhanced thorn and debris resistance, while a thinner inner layer adjacent to the rim minimizes overall weight. The 32 mm Schrader valve stem allows for easy inflation using standard pumps. Designed for 20 × 1.5–2.2 inch tires, this tube delivers reliable air retention and puncture protection without compromising ride efficiency.
