What It Offers

Product Size

TUBES SIZE: 2x schrader valve inner tubes suitable for most road bikes, gravel bikes, and mountain bikes with tire sizes 38mm-45mm, compatible with 700c, 29", and 27.5" bicycle wheel tires.

Higher Quality

HIGHER QUALITY: Our inner tubes feature a pipe wall thickness of 1.1mm, 15% thicker than other brands. This ensures higher air tightness and can withstand higher pressure. They are capable of handling high-strength impacts. Each inner tube undergoes a 24-hour air leakage test, guaranteeing good sealing performance, anti-aging, and shock absorption. The butyl rubber material used absorbs shocks on bumpy roads, making your rides more comfortable and safe.

Material

MADE OF OUTSTANDING BUTYL RUBBER: Our bicycle inner tubes are made with premium butyl rubber, which has higher air tightness than natural rubber. This material ensures perfect airtightness and is ideal for manufacturing inner tubes.

Easy to Use

EASY TO USE: Our inner tubes fit 700, 29", and 27.5" wheels. Please confirm that your bicycle tires are suitable before purchasing. The standard 35mm schrader valve is compatible with most standard rims. Installation is quick and easy. Follow the inflation guide when pumping up your tires. Replacing an old tire inner tube takes just a few minutes, saving you both time and effort.
