Schwalbe 16x1.125-1.375 40mm SCV4 Tube

Schwalbe standard bicycle inner tube no. 4. For bicylce tires in 16" inch (ETRTO 37-340, 28→37-349). Retains air for an above-average length of time. Thanks to the best material quality and uniform wall thickness. Maximum reliability that has proven itself millions of times over.

Note:

Only a SCV pump head adapter or SCV pump head is required for easy inflation with a single click. It is also possible to inflate your tires with a normal SV pump with a clamp-on or push-on head function (screw-on are not compatible). Thanks to this reverse compatibility, you're never stuck. With a normal SV pump, it is not possible to check the air pressure.
