Continental Compact 20 Valve Auto 32/47-406/451 inner tube is a 20-inch bicycle tube designed for 32–47 mm wide tyres used on kids’, BMX, folding, city and compact bicycles.

Key Features

Construction and Design
The tube is made from butyl rubber, which holds air well and is suitable for regular everyday use. The elastic material allows the tube to adapt to the inner shape of a compatible tyre and maintain stable pressure.

The Compact 20 version covers 20-inch tyres with 406 and 451 mm ETRTO rim diameters. This is practical when one tube is needed for different 20" wheel standards.

Main Functions
The tube helps maintain the correct air pressure in the tyre and supports smooth bicycle rolling. When installed correctly, it reduces the risk of air loss and helps the tyre perform consistently on everyday routes.

The Auto valve, also known as a Schrader valve, is widely used and easy to inflate with most bicycle pumps and compressors. This makes it a convenient choice for kids’, BMX and folding bikes where simple pressure top-up is important.

Use and Compatibility
The tube is designed for 20" wheels with tyres whose ETRTO size falls within the 32/47-406/451 range. It fits 32–47 mm wide tyres, so the size marking on the tyre sidewall should be checked before installation.

This model can be used on kids’, BMX, folding, city and compact bicycles, provided the tyre size matches the stated range. The rim must be compatible with an Auto valve.

Additional Features
The butyl construction requires little maintenance and is well suited for frequent use. The tube can be used both as a main replacement part and as a spare tube on rides.

Its compact packaging makes it easy to carry in a backpack, bicycle bag or repair kit. During installation, the tube should not be twisted or pinched between the tyre and rim to avoid damage.

Summary
Continental Compact 20 Valve Auto 32/47-406/451 inner tube is made for 20-inch bicycles with 32–47 mm wide tyres. It is best suited for kids’, BMX, folding and compact bicycles that need a reliable butyl tube with a convenient Auto valve and compatibility with several 20" tyre standards.
