What is your new steerer made of, steel, aluminum or carbon? All1-1/8" steerers have an OD of 1.125" but a steel steerer has an ID of right around 1.00" while carbon steerers have an ID of around 0.85" to 0.95". If your steerer is a different material from the old one, that could explain the ID size difference.
