Review on 🚲 Helonge 26 Inch Bike Tube 26x1.95-2.125, 2 Pack Bicycle Inner Tube with Schrader Valve, 32mm - Black by Rusty Heredia

China junk! One of the hoses developed a slow leak after 2 months of use. I traced this back to the junction of the rubber that forms the base of the valve stem and the tube itself. So I went to replace it with another tube that was in the same pack. After playing around with them for 1/2 hour trying to get the valve stem protruding far enough out of the wheel I compared them and found that the second pipe (which I carried with me as a spare) has a valve stem, which is 1 to 2 inches shorter than first! The photo shows two Helonge tubes, with the top one having a significantly shorter valve stem. Of course, this is more than a 30-day return window. Not a lot of money, but a lot of pain.
