Salyut Bicycle Inner Tube Teen (24", 37-533)

Bicycle inner tube 24"/37-533 for 20-24" wheels for teenage and mountain bikes

Nominal diameter (ETRTO) – 533 mm
Bead seat diameter (wheel diameter) – 24 inches
Width – from 1 1/2 inches (37 mm)
Valve type – AV 35 mm (Schrader, automotive) – the most popular valve type in CIS countries

This is a specific Soviet/post-Soviet wheel standard 24 inches (rim diameter 533 mm, used on the legendary "Salyut", "Salyut-S", and "Voskhod" bicycles).

Please note: This inner tube is NOT compatible with modern teenage or MTB bicycles with 24" wheels (where the modern ISO/ETRTO standard is 507 mm). The 533 mm bead seat diameter is larger than the modern 507 mm.

Bicycle inner tube 24" x 1-3/8 (37-533) AV — for "Salyut" bicycles

The 24" x 1-3/8 (37-533) bicycle inner tube is designed for installation on classic road and folding bicycles from the Soviet and post-Soviet periods with a 533 mm rim diameter. The tube is made of an elastic and durable rubber compound (butyl/rubber), ensuring long-term air retention and puncture resistance.

Key features and benefits:

• Special 533 mm standard (24x1-3/8): Perfectly fits the bead seat diameter of "Salyut" type rims (not to be confused with the 507 mm standard for modern mountain bikes).
• Schrader valve (AV): Allows for easy inflation with any car pump or compressor at gas stations.
• High elasticity: The 37 mm (1-3/8") width allows for stable performance in tires ranging from 37 to 47 mm wide.
• Excellent pressure retention: High-quality material minimizes natural air leakage.
