Durable Tubes that Go the Distance!!!
After logging many miles on my bike, my old inner tubes were well past due for replacement. I decided to try the 700C Heavy Duty Bike Tubes (700x35C/38C/40C/43C) with the AV48 Schrader Valve. I am thoroughly satisfied with this purchase. The tubes fit my tires perfectly, which can sometimes be tricky with replacements, and the installation was hassle-free. More importantly, these tubes have proven their durability. After significant mileage, they are still holding strong today, maintaining pressure reliably and providing peace of mind on the road. They are clearly a heavy-duty option that lives up to the description. This quality and longevity made them well worth the money and a great upgrade for my cycling stability.

You can actually get air in these and they hold well
Good tubes nice to get rid of those new style tubes almost impossible to get air to stay real junk. The old stuff works just fine.

Works
Worked like a charm I replaced my old bike tube and this one has been working for the past couple of weeks without an issue, no loss of air.

It is thicker and heavier.
It is, as they claim, thicker than other tubes. Hopefully it will resist the stickers better! So far, so good!

Maybe why they sell in a two pack
I replaced an existing tire and decided that it should have a new tube to go with it. The tire was worn and a couple of years ago it had a flat that I patched. So I deflated the tire and removed both tire and tube. I checked the rim and found no sharp edges. I replaced with the new tube and tire using the handy plastic tools the tube company provided with its product. The tube does not have a max or minimum air pressure but the tire states 50 to 75 so I inflated it to 60. It held that pressure over night and the next day I set off for a ride. Everything was great but at about 5 or six miles it went flat and quickly. I walked it back to a WAWA and filled it but it went flat in about a quarter of a mile. I again walked it back and not having any tools I purchase a can of flat fix filled it to 60 and after checking several times decided to finish my ride of an additional 15 miles. Great the flat fix worked. I sat and had a lunch but when I came back the tire was flat. I was able to walk the bike to a bus line and get back home where I took the tire and tube off the rim. The leak is a tiny pin hole along the seam opposite of the valve stem. I have cleaned the tire and checked the rim and found nothing that would have made a puncture. It is my opinion that the tube was defective.

Great inner tubes
Gets the job done. Replaced my inner tubes after a few years of use which I should have done much earlier. I've had them for a few months now and haven't needed to pump the tyres at all. Previous ones kept passively leaking after a few punctures which I had to repump every few rides.
