Swap out blown rubber with this lightweight TPU inner tube built for 20 inch BMX and MTB wheels. You get a tight dimensional match for rims labeled 406 or 451, delivering consistent rolling performance after a roadside repair. The refined TPU blend stretches easily during installation yet seals firmly against slow leaks across tire widths from 1.0 to 2.4 inches. Pick the valve profile that aligns with your spoke holes and enjoy faster inflation along with steadier pressure retention through jumps and hard corners.

You should gently pressurize the tube only until it forms a round shape before seating it in the casing. Hand pump usage prevents seam strain and protects the valve core from blast pressure. Watch your gauge when riding over sun baked blacktop, since ambient heat naturally raises internal tension during the day.

  • Material: Flexible TPU rubber maintains strong air retention and reduces overall rolling weight.
  • Fit Range: Compatible with 20×1.0–1.5(406), 20×1.75–2.4(406), and 20×1-1/8(451) tire profiles.
  • Valve Styles: Available with Presta (FV) 45mm or 65mm stems, plus Schrader (AV) 45mm.
  • Unit Mass: Ranges roughly from 32 grams for narrow builds to 52 grams for wider casings.
  • Pressure Limit: Safely handles inflation up to 5 bar (72 PSI) under normal conditions.

Package includes: 1 × 20 inch TPU inner tube configured to your chosen size and valve specification.

Never attempt full inflation while the tube rests loosely outside its outer tire. Folding the valve stem inward before pumping encourages even expansion and stops accidental pinching. Respect the 5 bar ceiling and account for temperature shifts before hitting dusty trails or parking gear near heaters. Deflate stored tubes to about 1 bar (15 PSI) when cabin temperatures approach 60℃ to preserve valve flexibility.
