RALSON inner tube 28 × 3/4–1.0 (18/25-622) – AV car valve 40 mm, 128 g

RALSON 28 × 3/4–1.0 is a bicycle inner tube intended for bikes with 28-inch wheels and narrow tyres 18–25 mm wide. With a weight of 128 g, it is a practical choice for road and sport-oriented cycling, where functionality, low weight and reliability matter.

The tube is fitted with a 40 mm AV (Schrader) car valve, which allows convenient inflation with compatible bicycle pumps and car inflation devices.

It is suitable as a replacement tube after a puncture or as spare equipment for rides.

For narrow road tyres 18–25 mm

The tube is intended for tyres with a rim bead seat diameter of 622 mm and a width of 18 to 25 mm.

This size is used mainly on road and sports bikes with narrower tyres.

The compatibility range includes, for example, the following tyre sizes:

• 700 × 18C (18-622)
• 700 × 20C (20-622)
• 700 × 23C (23-622)
• 700 × 25C (25-622)

The tube is a practical solution for cyclists who use narrow road tyres and are looking for a matching replacement tube with a car valve.

AV car valve – length 40 mm

RALSON 28 × 3/4–1.0 is fitted with an AV (Schrader) car valve with a length of 40 mm.

The car valve is popular thanks to its ease of use and the wide availability of compatible inflation devices.

Advantages of the AV car valve:

• Easy and convenient inflation
• Compatibility with pumps for car valves
• Can be inflated with a car compressor
• Practical length of 40 mm
• Simple pressure checking and topping up

Important: Road rims often have a narrower hole for an FV (Presta) valve. Before purchasing, it is therefore necessary to check that the rim allows the wider AV car valve to be fitted.

Weight 128 g

The tube has a stated weight of 128 g.

This figure is useful for cyclists who want to know the weight of the individual components of their bike and take it into account when choosing replacement equipment.

The tube can also serve as a spare item in your kit for longer road rides.

A practical choice for road cycling

RALSON 28 × 3/4–1.0 is suitable for regular use on bikes with narrow tyres.

It is used for leisure rides, sporty riding on asphalt roads and daily commuting on a compatible bike.

For correct function, it is important to observe the recommended inflation pressure according to the values stated on the tyre and rim.

When fitting, we recommend checking the inner surface of the tyre, the condition of the rim tape and the correct seating of the tube.

Suitable as a replacement and spare tube

Thanks to the size range 18/25-622, the tube is suitable for several widths of road tyres.

It can serve as a replacement for a damaged tube or as a practical spare on longer cycling trips.
