A good frame pump makes it easier to get your tires up to a high pressure in case you do get a flat. I ride with a spare tire, a patch kit, and a frame pump. Many's the time I've had to use my pump over the years. I would never rely on just CO2 cartridges. A frame pump is a lot easier to get you tire up to high pressure than a mini-pump.

What do you mean you carry a pump in your bag? There is no way I could get a pump in my under-the-seat tool bag.
