Rode for months and no flat. I buy tubes to carry with me and a week later.....a flat. Go figure. Guess it's better than a flat and not tube.

We carry these as spares in our bike bags incase we get a flat tire while riding bikes. Perfect!

Easy install, rock‑solid air retention, and excellent value. Fits Redline Proline Junior well. — highly recommend this Schwalbe SV6 pack!

My bike was sitting for two weeks with a flat tire in my garage. I looked around for the inner tubes locally and they were very expensive. So I said let me go to my trusted and faithful Amazon. I looked through Amazon and they had a pair. So I thought this would be a great time to replace my tubes and, make my bike rideable again highly recommend

Great tubes, but make sure you really tighten the valve stem.
