Replacement Bike Tire Tube, Bike Inner Tube, Standard or Self Sealing, Schrader Valve, Durable Construction, Replacement for Bicycle Tires

This tube has held up much longer than any standard inner tube I have used. A couple of things to know: 1. Because the sealant can clog the valve, pressure readings from pumps or gauges are often inaccurate. I simply checked by feel, which worked fine for me. 2. When the tube finally reached retirement, it was almost impossible to remove. It would not inflate fully anymore, but it also would not deflate. Since my tire was still good, I did not want to damage it. Even driving nails near the valve did not release the air, because the sealant sealed them instantly. In the end, I had to saw off the valve to let the air escape, which was a strangely satisfying moment. Bottom line: It truly does what it promises. It seals punctures extremely well, and you will never be stranded with a completely flat tire.

The tube is very good quality, had no issues replacing it. Hopefully the self contained sealant will at least hold me for a very small puncture until I get home. There are a lot of pine needles on the ground right now. They are expensive however, I bought one a week ago, then I ordered another one days later and the price was up 27%. The cost went from $11.04 to $13.99 each. Tariffs anyone ? So a good product but I'll shop around for pricing on other brands.

Got 2 pack of 700c x 35-42 mm Self-sealing tubes. Quality and feel looks good. One of them bursted just few mins after filling up to around 70 psi. (The tire says 55 to 75 max). Would I get a replacement? Update: After calling the customer service, and filling the mentioned form and sending photos, they sent a replacement tube in less than a week. And, that's been working fine.

Quality Tube, good fit, but description is inaccurate. I like the valve stem to be as short as possible. Preferably no longer than an inch after sticking through the rim. The description for this tube indicates that the valve is 1 inch, but as you can see in the picture of the stem after being installed on my rim, the valve is actually over an inch and a half. But also, as you can see in their description, measurements are all whacky. They say the "Item diameter = 706 Yards" ?????"

These tire tubes are my go to for long lasting tires. I live in California, and here in California we have a lot of goat head puncture-vine thorns lining the bicycle trails. I absolutely have to rely on the sealant in these tubes to be able to just pump up the tire, after removing one of these nasty thorns, and then continue on my way. I pair up the tires with Rhinodillo brand tire liners to guard against the sharp thorns. One of these days, I will probably try to convert my tires to tubeless, but in the meantime, these are my bicycle tire tubes of choice.

Good quality bicycle tube

Todo bien.

Had to return one of them due to a leak but worked fine after replacing the bad one. They are mostly staying inflated after a few weeks but still slight air drain. I guess they all do that.

Desde que las puse no he tenido problemas, así que cumplen su función y están excelentes! Si tuviera más bicicletas, les pondría estas mismas.

There are so many different-sized tires available today it was great to find the exact size I needed at a reasonable price.

Good looking tube that has done hundreds of miles and still going strong

False advertising. Tubes were suppose to be self-sealing but nothing on the product or packagjng mentions a self-sealing feature.

Amazon, get your description right....
