DURO Bicycle Tube – Reliable Butyl Tube for Multi-Size 700c / 28″ Hybrid Tires

The DURO Bicycle Tube is a high-quality, dependable product from the trusted DURO brand, engineered for reliable performance on utility and hybrid bicycles. This tube boasts excellent multi-size compatibility, fitting tires with widths ranging from 700x38C to 700x40C (and 28×1 1/2), making it a versatile choice for many urban and commuter bikes.

The tube is constructed from durable Butyl Rubber, which provides superior air retention compared to natural rubber tubes, ensuring your tire stays inflated longer. The easy-to-inflate Moto Schrader Valve (American Valve) is widely compatible with most pumps and is robust against damage, making it the preferred valve for utility cycling.

Application Instructions

• Preparation: Ensure the tire casing and rim bed are free of all sharp objects, debris, and punctures.

• Insertion: Lightly inflate the tube to give it shape, then carefully insert it into the tire casing and seat it onto the rim.

• Seating: Partially inflate the tube, ensuring the tire bead is fully seated around the rim.

• Inflation: Inflate the tire to the pressure recommended on the tire’s sidewall (using a Schrader pump).

Pro Tips

• Verify Sizing: Always check the tire’s sidewall to ensure one of the listed sizes (e.g., 700x38C or 28×1 1/2) matches exactly before installation.

• Use a small amount of talcum powder inside the tire casing before inserting the tube to reduce friction and pinching.

• Always check the spoke heads and rim strip before installing a new tube to prevent flats.

• Store spare tubes in a cool, dark place to prolong the life of the butyl rubber.
