In had corrosion wear out one bottom bracket and lock a seatpost in my steel frame in 3 years. I even greased the seatpost, but a Massachusetts winter riding every single day will do that to a bike. I am now replacing the frame.

Framesaver isn't completely useless... I'll probably do it this time around. Some people really ride hard enough to want it. That being said, I don't care if it's rusty. I just want to keep riding.
