Which inner tube?

[roro75]

Hi all,

So my tires is a 700x45c, and need a new inner tube.
I want to buy locally asap and see theses two are the closest match:
700c x 35-44mm
29" x 1.75-2.125"

So my math gets 45mm to 1.772" equalivant.

I know the inner tube stretches, but would the 29" x 1.75-2.125" a better mach for my tire?

Less stretch so less prone to a flat maybe.

Thank! Total new to bikes, did my research and still need help, lol.

You’ll be fine using the 700c x 35-44mm.

Slightly narrower are easier to fit !
