If they come in their own individual box and from Amazon, then my experience has been that they are genuine. If they come from another seller and packaged 5 in a bag, then I have had horrible results and had to return them.

ContinentalBicycle Tubes Race 28 700x20-25 S42 Presta Valve 42mm Bike Tube - Value Bundle 5-in-1 Bicycle Tube 700c

Q: Are the cores on these tubes removable?

The valve core of the valve stem is removable.

Q: Is this product for wheel size 28 or 29 inches? connfusing description says 29, box says 28.

28in, 29in, and also 700c are the same diameter rim, they just refer to different tire widths. 27in is a different size wheel though, so look out for that.

Q: Have any of you tried the 20/25 in a 28 tire?

Hi, I hope this finds you super well. We wouldn't recommend trying. Continental makes the same tube designated "wide" which is meant for 25-32 width tires. Happy riding!
