The not-so-minor details
Finish Line Chill Zone
Velo Vita + TMO Sports
Chill Zone works like magic! Before discarding your rusted chain or giving up on a frozen crank bolt, a rusted derailleur spring, or a seized seat post, give Chill Zone a shot. Bike parts that normally need to be replaced can be reconditioned to ride another day.
A special refrigerant propellant freezes metal as low as -50°F/-45°C. This causes contraction of the metal and creates micro-cracks in the rust. A penetrating release agent then breaks down and flushes out the rust. With Chill Zone, most rusted parts will quickly regain full functionality.
After freeing seized or rusted parts, no lubrication is necessary because Chill Zone. leaves behind lubricant and rust inhibitors to protect parts and prevent further corrosion.
Simply spray the rusted part for 10 to 20 seconds and wait 60 to 90 seconds for the release agent to fully wick in and break the rust. For sever rust-welded parts, spray for longer and wait at least five minutes for maximum effect. When rehabbing a bicycle chain, soak one small section at a time.
