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.

Good cheap and easy to set up

First time replacing bike tubes in over a decade and decided to go name brand. Ordered two for my wife's bike and one was great, the second came with a hole near the valve and was leaking slime. Was an easy return but still a bit of a pain.

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 quality and correct size

great price thanks all fixed now

Total sham .. box came, excited as ever change the rear since that's the one that was bad then change the front just because it makes NO sense to have a not flat in the rear and a regular one up front ... So me and my lady riding and we are 2 minutes from our destination ( final destination seemed like for me) and we stopped at the store to grab some Pepsi and ice.. we back on the road again and out of the blue I'm doing cart wheels over the handlebars only to end up on my face with the rest of bike on top of me... At first I thought I'm dead , second was did this bike break in half ?? Did I just break my wrist , is my teeth still in my mouth!!!??? Wait what just happened? am I about to be ugly , have My smile ruined ?? So turns out something punctured the tire and some slippery fluid came out which made the tire come completely off the rim only to get caught up in the forks causing bicycle to stop instantly... Momentum sent me and the bike hurdling through the air and to the pavement.. my super power is I don't fall, never ever do I fall .. well last night I fell , tumbled , and came to a violent stop... My lady said it sounded like a crash ... Now I give this product a rating of 0/5 it does not work .. I'll be asking fory money back ..
