Review on iEllevie Bike Tube 26x1.5/1.75 F/V Presta Valve - Pack of 2 Tubes + Free Outdoor Headwear by Phil Anderson

Received this hose expecting it to be a standard valve in America. Maybe I missed something in the description, but apparently the valve on these cameras is European size? Significantly less. It has a lock nut to keep it tight to the wheel hub (strange). I've never heard of this type of valve. To fill the tiny valve, you have to manually unscrew an even smaller valve core before adding air. However, you will need the "American" valve adapter that comes with the tire. This adapter must first be screwed onto the tire valve. Then you can use a standard pump. it's a pain Unless you're in a country other than America that uses this tiny valve, I wouldn't recommend it. Otherwise the tire sits correctly on the bicycle rim and does not leak even after about 2 months. However, adding air is very inconvenient.
