Concord Replacement Bicycle Inner Tube, 26", 4 Pack, Schrader Valve

I had a tire I was constantly pumping up every time I wanted to ride my bike so I finally broke down and bought these replacement tubes. They are fantastic, changing the tube was simple and easy after watching some videos on YouTube. I have been riding for a few weeks and has not gone flat. They seem sturdy and to be high quality. The 4 pack means each tire cost $ 3.25 each. What a bargan!!! I recommend buying these if you can find them.

Such a great value for your money. Tubes are great quality and the price is beyond fair.

Great price for 4 tubes. Shipping was fast too

I'm very displeased with these tubes. They are defective and are not worth using anymore. Have tried in the past with the same results. There appears to be a bunch of tubes that you have that need to be thrown away Every time I use them within a day a hole is in them.

unfortunately I was only able to use two of the inner tubes. there's no purpose in buying a multipack of a item that is garbage. valve stems keep popping off and the inner tube is extremely weak at the inside surface area and has a tendency of pulling apart which opens the tube to leak's. Looks like a stress fracture failure. Looks like what you see on a old tube that's been in the weather.

1 tube right out of the box had a hole in it

I sure this is a good-quality Item, but all I received was an empty Box. I had no Issue getting a Refund immediately, but I haven't re-ordered yet. I will re-Rate when I do.

These are garbage. Do not waste one penny on them. They last about a day and then go totally flat. Better to get one good one than to spend your money on 4 that won't hold air for more than one day!

As useless as the phones they sell, don't work. And they will not return

Hole in one and bad valve on another right out of the box. Very poor quality.
