Inner Tube Radvik BIKE TUBE 29" x 1.95–2.25 AV48 — 29-inch Presta/Schrader Valve 48 mm

Radvik BIKE TUBE 29" x 1.95–2.25 AV48 is an inner tube engineered for 29-inch wheels and tyre widths between 1.95 and 2.25 inches. The tube is supplied with a 48 mm valve suitable for rims of medium depth and serves as a reliable replacement or spare for mountain and trekking bicycles. Designed for straightforward installation and effective air retention, it is intended for routine repairs and maintenance on road, trail and off-road rides.

Advantages

The tube is made to match common 29" tyre profiles and offers compatibility across a range of tyre widths without the need for size guessing. The 48 mm valve length allows easy access when using rims with moderate depth and compatible pump heads. Constructed to provide an airtight seal, the tube supports consistent tyre pressure and reduces the frequency of repeat inflation during short- to medium-term use. Its simple design makes it compact to store as a spare and easy to replace in the field.

Suitable for

• Replacement inner tube for 29" mountain bike tyres 1.95–2.25"
• Spare tube for trekking and commuting on hybrid bikes with 29" wheels
• Field repairs and roadside tyre changes during rides

Key specifications

• Wheel diameter: 29 inches
• Tyre width compatibility: 1.95–2.25 inches
• Valve type and length: 48 mm AV valve suitable for medium-depth rims
• Intended use: mountain and trekking bicycles, general off-road and on-road riding

How to use

Before fitting, check the tyre width and rim depth to confirm compatibility. Partially deflate the tyre, remove the bead from the rim, and extract the damaged tube. Slightly inflate the replacement tube to give it shape, insert the valve through the rim hole and seat the tube evenly inside the tyre. Re-seat the tyre bead on the rim, inflate to the recommended pressure printed on the tyre, and check for proper seating and leaks before riding. Use appropriate tools such as tyre levers and a pump compatible with AV valves as needed.

Usage recommendations

Carry this tube as a spare for rides on trails and varied terrain. Match tube and tyre pressures to rider weight and terrain conditions, and inspect the tyre and rim for sharp objects or damage before installing the tube to reduce the risk of repeated punctures.
