A good choice for anyone replacing a punctured or ageing tube on a 20-inch bike with 1.75–2.125-inch tyres and a Schrader valve.
Keep your 20-inch bike rolling with the duro Schrader Valve Tube. It is sized for tyres from 20 x 1.75 to 2.125 inches, making it a suitable replacement for a range of children’s, BMX, folding and compact bikes using this wheel size.
The Schrader valve is the standard American style, so inflation and routine maintenance are simple with a compatible pump. The 48 mm valve length provides practical clearance through the rim, while the tube’s sturdy construction is designed to handle normal road demands and support a smooth ride.
Select the quantity that suits your workshop or riding plans: tubes are available in packs of 2, 5 or 10. Before ordering, check the tyre sidewall and confirm that both the 20-inch wheel size and 1.75–2.125-inch width range match your existing tyre.
