🚴 Set of 4 Continental 28-Inch Presta Valve Inner Tubes with 42mm SV for Enhanced SEO Review

I love these tubes! I've been using them for ages, they fit a variety of tire sizes (I ride big tire touring bikes), I've only had one tube with a factory issue (stem base seal issue).

I use these tubes on my gravel bike and Conti is always the best. I put latex in my gravel pipes to prevent them from being punctured, so it's important that they have removable valve cores. So I have enough inner tube for the whole season. If you find a 4-pack deal like this, go for it.

Bought four packs, tire was flat twenty minutes after inflation. I checked a large laundry tub and found no holes in the tubes but air was leaking from the valve core. This is bad quality. Don't waste your money and time with these tubes; unless you enjoy wasting time changing tubes for no good reason. These whistles are cheap because they are very cheaply made. You get what you pay for, it's awful pipes.

I was excited to buy a set of 4 tubes for my upcoming long distance tour, but my excitement quickly turned to fear when one of the tubes ruptured when it was only rated at 35 pounds per Tube inflated was square inches. Not only did it destroy the inner tube, but it also damaged my new tire. Something I didn't even think was possible. Thinking it was an accident or that I had misjudged the psi, I pumped up another one, only to an even lower psi of 30. About a minute later, it exploded again…

Before I bought these cameras I saw some negative reviews and thought, well how bad are they? After they arrived I installed one in my bike tire and pumped it up , and there it burst and deflated. I tried a second one with the same result, inflating the tire to just 60psi. In comparison, the Bontrager tube I used to have lasted 10 years and I've regularly pumped it up to 80psi or more. The reason I'm writing this review is because I don't want someone riding a bike for a long time, running into

I hate these tanks but they are literally the only ones I can find online for 700 x 37c tires. I had over 8 hoses with a valve stem when I just unscrewed the cap to vent. Literally at least 8 did the same. They break very easily. I have to order 8 tubes at a time and take 4 extra tubes to work because they suck terribly. But like I said, I can't find any other brand of tubing for my bike. I would go tubeless, but that would be $400 total for my bike. It's almost worth it 'cause I buy so many of
