There is no way to make an informative answer to that question. You could use great components and wheels on a steel bike and it would be about 20 pounds. For a CF bike stock wheels and entry level components would put you at about 20 pounds. In my experience a bike with quality wheels between 1300 and 1600 grams will climb better than the same bike with 2000 to 2200 gram stock wheels. If you consider climbing faster better. Or at least it will seem to climb better. IMHO
