You know, if it was a big problem it seems to me that you
could have the spare tube already looped inside the triangle, bag it up or something and strapped to a stay down by the axle. That way you could change your tube also without having to take the wheel off, or even having to loosen it. Heck maybe you could keep 2 or 3 tubes that way just in case.
