Schwalbe AV17 Inner Tubes 700 x 28-45c / 28" 27", Schrader Valve (2 Pack)

Easy to install, holds air without needing to be touched up. They have maintained pressure for over a month!

Best inner tubes I've purchased in years!300+ miles on these tubes; no pinch flats or punctures!Running them at 4 Bar with Gravel tires....Like others have said, the quality of OTHER tube manufactures has gone down hill, since the pandemic!

These are very well made with a nickel plated metal valve stem and core and thick rubber on the tube portion. It is provided with a nickel plated metal knurled nut. The valve cap is rather cheap plastic and is the only downside to this item. Quality seems to be consistently good, I’ve only had one bad tube out of the twenty or so I’ve had over the years.

The quality of these "standard" tubes from Schwalbe, are better than the recent purchases I made at my local bike shop of "standard" tubes from two other well-known bicycle manufacturers. There is no question that bicycle inner tubes have deteriorated in quality just in the last few years. While most tubes are all made in China, in the same factory and probably to the same quality specs--it is clear that the "standard" tubes being made today, are of a much thinner and less robust quality of material than those made just a year or so ago. All four of the other two well-known brands I purchased at my bike shop, exploded and ripped down the seam of the tire. I used a rim liner, I used 'green slime', I slowly pumped air into the new tube and gently installed in the rim--no avail, they exploded upon just 20 PSI. I hope the Schwalbe lasts. So far, so good. I successfully installed my first inner tube from Schwalbe and had a great ride yesterday. I'll report back on durability. Summer riding can be brutal.

Perfect inner tubes, I recommend.

I grew up in the Arizona desert. I raised 9 children. I built bikes as a kid. That's a lot of fixing flat tire. Goat heads do it repeatedly too!So, yes, I've replaced and patched tubes too.However, never until now have I gotten excited over inner tubes. Nope, not even the slime filled tubes.I literally got excited about these Schwalbe inner tubes.Schwalbe is outstanding. The rubber is thicker. The valve stem threads all the way down the stem and retaining screw-ring are amazing allowing for the stem to be secured protecting against the stem getting sideways and sheared off. Even the valve stem cap is Premier quality, clear, and cool looking. The best quality inner tube I've ever purchased in my lifetime, and paid less than competitors. It cost less than any at Walmart and definitely less than a bike shop.I will ALWAYS by Schwalbe from now on. Yes, these fit perfectly. I highly insist you buy these, instead of patching even, you will have greater peace of mind too. I would patch a Schwalbe, because I am increasing the life of a higher quality product, not helping a poorer quality tube punish me again.Schwalbe all the way, every time for me. No, I'm not paid to review these. I paid for these for my wife's Schwinn bicycle. Mine will get these too.

I give these five stars because, not only are they a great brand overall, but I love the two little things that separate them from the others. 1 - the have a nut that locks the stem in place and keeps your tube from sliding around over the many miles you will put on it. It keeps the stem at a 90 degree angle to the rim and greatly reduces your chance for a leak at the point where the stem meets the tube. Every flat I have had in the last 4 years has been because of this. 2 - the valve cover is a better plastic than typical and won't end up failing on you in a few months like most valve covers do. Worth every penny.

I very disappointed with this product. I installed the first tube in early Feb. I should add here that I am very experienced replacing bike tubes, partially inflating in the tire to prevent the tube from getting caught and carefully inspecting the tire for any perforations. The install went well. On March 15th, the replacement tube went flat. I removed it and saw that these tubes are constructed with two seams traveling completely around the inside and outside of the tube. Upon close inspection, I noticed that the leak developed in one of the seams. I patched it, reinstalled the tube, inflated it to 50 psi and two days later, the tire was flat again. I carefully inspected the tire for any type of perforation but there was none. I assumed my patch failed but it turned to be yet another failure along the seam not far from the first. I am not even going to attempt to patch it as it is quite obvious that this seam will fail yet again. I would definitely avoid these tubes as I have included pictures of the second tube and can see the seams. I can only assume this tube will fail as well.
