Itw Global Brands BCYCL INNR Tube RUBR 20"

I bought these tire inner tubes with slime inside to avoid the hassle of constant flats, and they’ve been fantastic. The slime does a great job sealing small punctures automatically, so I haven’t had to stop and patch a tire even once.Installation was pretty straightforward, and the tubes feel sturdy and well-made. The added weight from the slime is barely noticeable, and the ride feels smooth and reliable.If you want a low-maintenance solution to keep your tires leak-free, these inner tubes are definitely worth it. They’ve saved me a lot of time and frustration!

Love it

High pressure, fitted, big huge hole, flater then a pancake, great performance racing product, lightweight.

Hasn't gone flat. That makes it good

I like the product because it stands up to the small thorns in my neighborhood. So I fix flats less frequently. The last two-pack I bought had a faulty tube with a tear in it. I did keep the tube in the box until I needed it which was way past the return date. At this point I will continue to use the product but will be mindful to check upon receipt.

Great product. I blew out a tire on my bike a week after I got it on a bad hit from a sharp pothole on Brooklyn streets. After limping the bike home, I went to Amazon to order a bottle of Slime and a new tube (used it before to great results.)I saw a Slime inner tube, ordered it, installed it, inflated it, and no problems since. It's so much easier thanA. Removing the air from the inner tubeB. Removing the tire stem (if you don't have the actual tool the Slime cap may not always work)C. Injecting Slime into inner tubeD. Replacing tire stemE. Inflating tireF. Figuring out what to do with all the extra Slime in the bottle if you've already inserted into both tubes.I tempted fate, went to the same street in Brooklyn, intentionally hit the same pothole at approximately the same speed and angle as the first time, and voila! Not a problem. I've been riding on this tire and tube for three months now without any problems at all.

I been using these tubes for 30 plus years and have never had any issues, seems some of the bad reviews are probably because they didn’t follow the instructions on the box and or inexperienced with tube installation. I have had these tubes outlast many tires, and I have never had to replace them ever again. This is the second one for my daughters bike, I did the front tire two years ago instead of just patching the original tube that came with the bike when it got a leak in it, now it was the back tire’s turn.

Used once and not even in the mountain just at the park for 3 miles. Next day the tires is deflated. Checked it and valve stem is open. Waste of $
