Has anyone actually had problems with frames rusting from the inside?
If you store your bike inside and are diligent about removing the seatpost after riding in the rain, I don't think you'll have any internal corrosion. If water pools in the BB area regularly (ride in rain, store it outside, never remove the post), the frame will rust. Granted, this will take years, but some of us (especially those who care enough to participate in online bike forums) would like to keep the frame for many years or at least be able to sell the frame/bike in excellent condition.
