Fits 20 inch wheels with 1.75 to 2.125 inch tyres

These two inner tubes suit 20 inch wheels ranging from 1.75 to 2.125 inch tyre widths. They use a US valve measuring 32mm in length and 8mm in width. Cyclists needing a direct replacement for punctured tubes on children's bikes, folders or BMX models will find the pair convenient.

Rubber construction with standard US valve

Each tube is made from black rubber and features a smooth slick pattern that balances grip with rolling resistance. The US valve follows the standard 32mm length and .31 inch width, fitting common rim drillings without adapters. Normal inflation pressure holds well for everyday riding on pavement or light trails.

Pack includes two tubes for immediate spares

The package supplies two identical tubes so a rider can repair a flat and still carry a spare on longer trips. Under sustained use the rubber resists pinch flats across the stated width range. Riders who need Presta valves or tubes for wider mountain-bike tyres should look elsewhere.

Questions about this item

How do I install the 20" inner tube with the 32mm US valve without pinching it?

Partially inflate the tube so it holds its shape, seat the 32mm US valve through the rim hole first, then tuck the tube evenly inside the 1.75 to 2.125 inch tyre before fully inflating.

What maintenance will these rubber inner tubes need over time?

Check pressure weekly; rubber naturally loses air. Inspect for cuts or perishing after every few rides and replace the tube if the 32mm US valve core leaks or the rubber cracks.

What is the first limit I will hit if I run these tubes at the top of the 2.125 inch width range on long rides?

The 32mm US valve length may not clear deep-section 20" rims, so valve fit becomes the limiting factor before the 1.75 to 2.125 inch width range is fully used.
