Schwinn Replacement Bike Tube Schrader Valve, Self-Sealing, 27.5-Inch x 1.75-Inch-2.125-Inch, Black

The tape was off and hangging as if it didn't stick well it didn't look like someone tampered with it

Worked well

Replaced the tube...went flat after 1 ride...pumped it back up...went flat again...after removing the tube to see if there was a leak...lolw and behold the tube was leaking at the stem with a wet foam coming out of the tube! Faulty product! don't purchase

Works great.

I tried two other bicycle inner tubes and this one was a bit more but worth it for a new Schwinn bike.

Blew apart when I tried to inflate.

Friend of mine had a flat on his 1981 ten speed with really skinny 27" tires. He had not spare tube so we used my Schwinn Replacement Bike Tube which was 27.5" and alot wider. And even though it wasn't made for this application, it still worked and got him back on the trail and delivered the 10 plus miles back to our car. I will be getting another one to replace this one.

I bought 2 BiCycle self healing tubes. One of them was fine but other one had a quality issue/ a manufacturing defect. Post fixing my BiCycle tube/tires to 35 to 40 PSI, I took it for ride and my back tire went flat. When i opened it and it had a tear at the seam. I tried to fix the tear on the seam using the tube fix patch i got but it would not hold air at all. It is also hard to fix the tube using patch due to slime fluid that seems to flow out hence i had to hold it pressed when i applied the patch with Vulcanized rubber fluid. You can see the effort i put in to fix but nothing seemed to work.I think it is a manufatuting defect as tire seam had a tear from the first ride itself and Pressure was normal (35 to 45 PSI ) .I got one good and one bad tube so not sure i would recommend this Schwin slime tubes.
