RALSON OEM 28"/29" × 1.95–2.125 is a quality bicycle inner tube intended for bikes with 28-inch and 29-inch wheels and a corresponding tyre width. Thanks to its 1 mm thick wall, it offers a strong construction suitable for everyday use, leisure cycling and regular rides.

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

Thanks to the combination of a practical construction, versatile use and an affordable price, it offers excellent value for money.

Strong construction with a 1 mm wall

One of the main advantages of the RALSON OEM tube is its 1 mm wall thickness.

This construction provides good resistance to ordinary mechanical stress and is suitable for regular use of the bicycle.

The stronger design can help to reduce the risk of some types of punctures compared with ultralight thin-walled tubes.

The tube is therefore suitable for cyclists who prioritise practicality and durability over minimum weight.

Size 28"/29" × 1.95–2.125

The tube is intended for 28-inch and 29-inch wheels with the corresponding rim diameter and tyres 1.95–2.125" wide.

On ordinary bikes, the 28"/29" designation corresponds to a rim bead seat diameter of 622 mm.

The declared width range is approximately 50–54 mm, which allows use with many trekking, cross and mountain bike tyres.

Before purchasing, we recommend checking the size of the original tyre and compatibility with the rim.

AV car valve – length 40 mm

RALSON OEM is fitted with an AV (Schrader) car valve with a length of 40 mm.

The car valve is one of the practical solutions for everyday cycling 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 designed for car valves
• Can be inflated with a car compressor
• 40 mm length suitable for many common rims
• Simple pressure checking and topping up

Before fitting, it is important to check that the rim has a hole intended for a car valve.

Versatile use for everyday cycling

The RALSON OEM tube is suitable for ordinary use on mountain, trekking and cross bikes with a compatible tyre size.

It is used for riding on asphalt cycle paths, paved tracks, gravel and ordinary forest routes.

It is a practical choice when replacing a damaged tube and can also serve as spare equipment for longer cycling trips.
