SCHWALBEAV7 BMX Inner Tubes 20" x 1.5 - 2.40, Schrader Valve (2 Pack)

These tubes hold air much longer than ordinary ones. They have a Super high quality stem with a little nut that holds it to the rim which comes in handy when installing them. They are a good match with Schwable tires which are also thick and durable.

I like to add tire sealant of some sort, like Slime to prevent flats. Schwalbe tubes are somewhat on the thin side, so you will want to use a tire sealant or tire liner. The overall quality of the tubes are excellent.

Inner tubes fit as described. No issues so far.

Good quality...not skimpy tubes!Not sure of durability...have about 25 miles...at 28psiDoubt they'll fail prematurely

Cycling forums have numerous posts about this product’s unreliability. I’ll include my own here. I had 3 failures within 12 months. In each case, the tube failed with a longitudinal split on the rim tape side of the tire (different tires). And I thought I was paying for quality and durability. Nope.

They’re inner tubes. Seem to be good quality and hold air like they’re supposed to. Noticeably better than the stuff you find in a department store.

Put two on my bmx. They’ve held 60 psi for nearly 3 months now. Valve stems are the highest quality I’ve seen. Love the clear caps.

It worked and described. Installed it with no issues.
