Ultra-Light TPU Material
Much lighter than traditional butyl inner tubes, improving acceleration and climbing efficiency.
Schrader Valve Design
Easy to inflate, strong valve structure, compatible with standard pumps.
High Elasticity & Air Retention
TPU construction offers excellent flexibility and stable pressure performance.
Wide Compatibility
Covers MTB, gravel, folding bikes, BMX, and children’s bikes.
Do NOT inflate the tube heavily before installing into the tire.
Before installation, slightly inflate (≤5 PSI / 0.35 BAR) to check for air leaks.
During installation, ensure the tube is evenly seated against the tire inner wall before full inflation.
Never inflate the tube alone over 6 PSI, otherwise permanent damage may occur.
