Functionality Breakdown

Heavy Duty Inner Tube: 700x35C, 38C, 40C, 43C FV48mm (ETRTO: 35/43-622)

Looking for a heavy-duty inner tube for your bicycle? Our 700x35C, 38C, 40C, and 43C FV48mm inner tubes are perfect for a wide range of applications. These inner tubes enhance the ductility of heavy-load tires, expanding their scope of use.

These inner tubes are designed to be compatible with a variety of bike tires, including 700x35C, 700x36C, 700x37C, 700x38C, 700x39C, 700x40C, 700x41C, 700x42C, and 700x43C. This flexibility means you can use them with mountain bikes, road bikes, cruiser bikes, and electric bikes.

Excellent Shock Absorption: Our heavy-duty, strong, and highly durable butyl rubber inner tubes provide excellent shock absorption. These inner tubes are a perfect shock absorber, reducing vibrations and eliminating shocks from bumpy or rough surfaces. The thick butyl rubber ensures maximum ride comfort and upgrades your cycling experience.

Heavy Duty - Air Tightness: By using high elasticity butyl rubber and EPDM rubber, the thickness of our inner tubes is increased by 40%, enhancing air tightness by 200% compared to ordinary butyl inner tubes. After inflation, the tire can maintain a higher air pressure for 6 to 9 months, drastically reducing the frequency of reflation.

Heavy Duty - Ultra Durable: Our inner tubes have higher puncture resistance than ordinary inner tubes and can better withstand friction and wear. The thicker body extends the service life of the tube, reducing the need for frequent replacements and lowering maintenance costs. This durability is especially useful for long-term use, especially with electric bikes.

Compatibility: These inner tubes are compatible with various models of mountain bikes, road bikes, cruiser bikes, and electric bikes. The increase in thickness also meets the needs of longer driving ranges and higher loads in electric bikes.

Installation: For easy installation and removal, these inner tubes fit 700x35C and 43C bicycle replacement needs. Ensure the valve position is correct during installation.

Tip: Before installing, check the inner tube in water; if there are bubbles, it indicates damage, and you can contact us. Make sure the valve position is correct to ensure proper installation. Note: Avoid punctures by sharp objects when inflating.

Note: This inner tube features a Presta valve core that is not removable.
