Mitas 20x1-1/8-1-3/8 Schrader Valve 40mm Tube (AV40)

20" (451) Tube

Sized for the 451mm 20" rim found on BMX race bikes, some folding bikes and recumbents, which takes a different tube than standard 406mm 20" wheels. The 40mm Schrader stem works with any pump.

The Schrader valve is the same style you'll find on a car tire, so it works with gas-station air, most floor pumps, and rims drilled for the wider valve.

Whether you're fixing a flat on a folding bike, a recumbent or a 20" BMX race bike, check for 451 on the tire and you've found the right tube.

Mitas bicycle tubes are made in Náchod, Czech Republic, where the factory has been building bicycle tires and tubes since 1929. The same line now also carries the Rubena name, with the same part numbers and construction.
