I've recently changed the default 700x35 tires and 35mm Schrader inner tube to 700x25 slicks with 25mm Presta inner tubes.
However whilst fitting the new tire and inner tube, I noticed that the inner tube had about an inch or two of excess length to it. This mean I had to tuck it into the tire, doubled back on itself.
I've doubled checked the inner tube packaging and it's definitively for a 700 diameter rim.
I presumed that it would sort itself out when I pumped up the tires. Is this normal?
