SCHWALBE AV6 BMX Inner Tubes, Schrader 40mm, 20 x 1.10-1.50 (2 Pack)

Good fit. Great quality.

I love the fully threaded metal valve stem and nut. I hate it when the tire and tube slide on the rim and make the valve stem misaligned, and then as I try to get it straightened out I always seem to overcorrect and make it go crooked the other way. This design eliminates that hastle. Also, when first going to put air into it (and if you ever get a leak/flat and need to air it up again) the valve stem doesn't push into the rim and make it difficult to attach the air pump. Other than that, there's not much to say. It's an innertube. It holds air. I've only ridden about 20 miles on it so far, so I can't comment on durability. The valve stem though is awesome, and if you've never used a tube with this design, I cannot recommend it highly enough. Happy pedaling!

Good fit easy instructions

Excellent tubes, zero issues, all great! I have changed tubes to Schwalbe on all four bikes. Why, because the cheaper tubes fail. Cheaper tubes seem to have common failure mode, leaking around valve stem where molded to tube. Cant realistically patch that!

Perfect tubes for my Schwalbe Marathon tires!

Update: I took a chance and bought another 2 of these tubes. I just had my 4th failure. Trike was just sitting in the garage, came out to yet another flat. Removed the tube and surprise - same exact spot (different tire/rim from previous 3 flats). Schwalbe definitely has a QC issue, or a manufacturing defect. I won’t be wasting my money on these overpriced pieces of garbage any more. Their tires are great, but their tubes are trash. I welcome a call from a company rep, but won’t be holding my breath. ———— Bought a pack of 2 of these highly regarded 20” tubes. Had a pinhole flat in BOTH tubes in the same brand new Schwalbe Marathon tire. Nothing in the tire - checked very carefully. The flats were on the outside, directly opposite the fill valve in the clearly identifiable seam. Looks like a QC issue to me. I’d love to hear from a Schwalbe rep on this issue, please. Have pics to support my claim. It’s a tough area to patch, so I’ll be replacing these.

Excellent product. Very fast delivery.

I like these tubes because I trust the metal valve won't fail. But twice now, I've had brand new tubes split at a seam. Of course, since these are backups for a future failure, they don't come to light until after the 30 day return policy. I guess the price I have to pay since, even with the failure rate, they are better than others I've used, esp. since it's hard to find 20" x 1.5".

Super Schlauch in speziellen Abmessungen. Was will man mehr?

Schwalbe make the best tubes, I run them in all my folding bikes and even my trailer. Good quality, easy to install, they hold air well and the Schrader valves are easy to top up. Patched a few over the years too and no issues there after. Cost is a hair more but worth it for the reliability.

After desperately searching the internet for bike tubes thin enough to fit my Giant Expressway 1, which by default comes with super skinny city tires. (Finding skinny tubes for 20" rims is not fun). Finally I broke down and bought these because they were the only ones I could find without looking overseas. They arrived, and they fit! And the quality is actually as good as advertized. I only needed to replace the one tube, and I can see the difference in how long it takes them to lose air. The Schwalbe tube takes approximately 50% more time before I need to pull out the pump again. I wasn't enthusiastic about the price tag at first (isn't all rubber the same?), but now I can confidently say they're worth the money.

The quality of the tube is good but no better than tubes from other brands selling at a cheaper price. The valve stem is a little bit on the short side. The price is expensive but it does not hold air any better than those from the cheaper competitors. I had my tires pumped to 70 PSI and they were down to 67 PSI the next day.

Decent quality
