Self-Sealing Bicycle Inner Tubes

Have had these tubes on the bike for about 400 miles. They work just like any other inner tube. Fill with air, works fine. One morning my wife and I went for a ride, and about six miles from home, something punctured her rear tire. (Sealant sprayed out the hole just like you see in the youtube tire sealant tests. ) And it went flat. I had a pump with us, and reinflated the tire. We pointed back home and got started. A few hundred yards later the tire was very low already. I inflated the tire again, and this time it sealed up! It has been holding 55psi for about 85 miles now. I'm going to replace tire and tube soon, but if you have a pump with you, clearly these tubes can keep a puncture from becoming an emergency, making it only an inconvenience. I'll be buying self-sealing Bell tubes for all of our tubed bikes from now on.

Good inner tube for my bicycle. I do wish that the valve stem had some kind of retaining clip or something to keep it in place. This is the first full size bicycle tube I've replaced. So maybe they're all like this. I'm not taking any stars away. Just making mention of this. Also, I can't speak of the puncture seal aspect of these. Hopefully I won't even need to find out. Otherwise, I'd say it's a good product at a decent price. I might just proactively buy a second one of these to replace the other tube. As they were the originals and very old. I can definitely recommend this tube to anyone looking for a good Value.

Hold air well. Good price. Easy to install.

It worked after a flat but eventually went flat again.

This is the 2nd set I got from them like this it was a cheap price compared to the box store. The only thing I didn’t like was the valves would seal tight and it would make it difficult to add air. Valves leak some no matter what it’s on and the sealant works too good.

Good cheap and easy to set up

Good quality and correct size

Terrible tube. Lasted exactly one month and one day. Couldn't even put air in it, didn't hold. Went to the bike shop to have him see what could be the problem. There was a small thorn size hole. The sealant didn't refill. I said ok, let me give it another try for the price. Let's see what happens this time

Buen producto 👍

Great product. Was new and vacuumed sealed! Great value and great product. Bell has been around a long time and is tested and true!

Worked as it should..

Excellent quality and value.

Haven’t had to use it yet but showed up as described
