## Long description

AUTHOR AT-MTB-26" AV32 26x1.75/2.20 black is a replacement inner tube designed for 26-inch bicycle wheels with tire widths from 1.75 to 2.20 inches. Fitted with an AV32 (Schrader) valve, this tube restores airtightness after punctures and provides a simple, reliable inflation solution for mountain and hybrid bikes that use 26x1.75–2.20 tires.
Advantages
The tube is made from durable butyl rubber that offers good air retention and resistance to minor punctures. The AV32 (Schrader) valve simplifies pumping with common floor pumps and compressors without requiring an adapter. Its size compatibility covers a range of medium to wide 26" tire profiles, enabling straightforward replacement and rapid return to service. The black finish is standard and compatible with most rims and tire combinations.
Suitable for
 26" mountain bikes with tire widths 1.75–2.20
 Hybrid and trekking bikes using 26x1.75–2.20 tires
 Emergency spare tube for trail or urban repairs
 Home or workshop inner tube replacement and maintenance
Key specifications
 Wheel size compatibility: 26 inches
 Tire width compatibility: 1.75–2.20 inches
 Valve type: AV32 (Schrader)
 Material: butyl rubber
 Color: black
How to use
To install the inner tube, partially deflate and remove the tire from the rim using tire levers, then inspect the tire and rim strip for embedded debris. Slightly inflate the tube to give it shape, position the valve through the rim hole, and tuck the tube evenly into the tire. Reseat the tire bead carefully to avoid pinching the tube, then inflate to the tire manufacturer's recommended pressure while checking for proper seating and any leaks.
Usage recommendations
Check the valve core for secure seating before installation and use a pump compatible with Schrader valves. Maintain recommended tire pressures for your bike type and terrain to optimize puncture resistance and ride comfort. Keep a patch kit or second spare tube on longer rides for added reliability.
