Tube 20" 1.75-2.35 Schrader Valve

This BBB Cycling inner tube fits 20-inch wheels running tires between 1.75 and 2.35 inches wide, covering common BMX, kids, and city bike sizes in one tube. A Schrader valve matches the valve style found on most BMX and kids' bike rims, so it works as a like-for-like replacement without needing a valve adapter.

The 35mm valve stem is long enough to clear most rim depths on 20-inch wheels without needing an extension. The tube works as a replacement for a punctured or worn original tube, or as a spare kept on hand for smaller-wheeled bikes such as kids' and BMX models, where flats are more common than on larger wheels.
