🚲 Two Pack of 26 X 4.0 Fat Bike Tubes with Schrader (Auto) Valve Review

Installed a tube on the front of my rad bike tonight, inflated to 20psi, no time to ride. In the morning the tire was completely flat. The next evening I replaced it with a second tube. This one seems to be holding air. I waited a week past the 30 day return period so I'm stuck. Dissatisfied. If you buy them, be sure to test both for leaks before the return period expires.

One might think that there is no difference in the quality of the tubing rubber. If you're talking about a thick inner tube, that might be true. However, this tube has a threaded valve stem so it can be locked securely. This will prevent the tube from slipping in the tire when the pressure is low and also prevent valve flex when the tire pump is connected. A nice touch that shows someone knows bikes.

Camera quality is excellent. Very thick and worked great in my 26 x 4.25 tires. Warning if you intend to use sealant in chambers like Slime, Stan's, etc. The hole at the bottom of the valve stem may be partially blocked by rubber during manufacture. . There was no problem with the air supply, but adding the slime to the tubes I received was a challenge. I found that inserting a drill into the valve opened the blockage and allowed the mucus to flow. Customer service is excellent! Eric responded…

Looks like a quality tube. One worked as expected and one was a problem. Went to install the first pipe. Failed to inflate with stationary bike pump. I started the compressor in the shop and it pumped up the tire. Even with the valve removed, the tire is not deflated. I poked around with the feeler gauge and forced it to deflate just enough air so the tube was on the rim. Tried to inject slime into the tire but couldn't inject slime into the tire. Played around with the pipe for an hour or so…
