Before you get the hacksaw out and begin cutting off seatposts, crank bolts, and other rusted, seized bike parts, give them a shot of Finish Line's Chill Zone and watch the magic. Chill Zone is not a lubricating grease. It's a refrigerant that freezes metal to as low as negative 50 degrees Fahrenheit. This process causes the metal to contract and thereby creates micro cracks in the corrosion and galvanically fused metal parts. After it does this, a penetrating release agent is able to break down and remove the rust. Most seized parts regain full use.
