Wet Lube is typically recommended for extreme conditions. Formulated with high viscosity synthetic oils, water repelling polymers, and advanced anti-wear additives. Wet Lube is Finish Line's strongest, longest lasting and most water resistant lubricant. Wet Lube goes on wet, and stays wet, to provide maximum drivetrain smoothness, extremely quiet rides, and ultimate rust protection in the harshest of environments. If you use Wet Lube for riding off-road or in dry climates, be sure to wipe the excess from parts to minimize the attraction of dirt and grime. Since 1994, when Wet Lube was first introduced, it has become the preferred lubricant for many professional on and off-road teams around the world. Use Wet Lube when you ride hard and long. Proven performance for 100-plus mile rides, muddy off-road conditions, long rainy commutes, and foggy salt-air coastal climates. A heavier, wet-style lubricant that requires a little more attention to drivetrain cleanliness, but delivers the ultimate in lubricity and protection.

Regular lubrication of bicycle chains addresses annoying squeaks and noises, and extends the life of the chain and drivetrain components.

Also works great as general-purpose light lubricant for use on bicycle brake and derailleur cables and housing, spoke nipples, and derailleur and brake pivots. - 4 fl. oz. (118 mL) bottle NOTE: Some painted surfaces can be sensitive to oil and grease. Clean off any excess oil or grease immediately. Test first on an inconspicuous area to see if it causes a stain or discoloration.

Chill Zone™ is arguably the industry's most advanced rust-busting penetrating lubricant. It simply works like magic! Before giving up on a frozen crank bolt, a rusted derailleur spring, a seized seat post, or discarding your rusted chain, 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 to as low as -50°F/-45°C. This causes contraction of the metal and creates micro-cracks in the corrosion and galvanically fused metal parts. A penetrating release agent then breaks down and flushes out the rust. With Chill Zone, most seized parts regain full functionality.
