Motorex Joker 440 is a fully synthetic penetrating spray that lubricants and displaces water. Perfect for freeing up frozen parts, it cuts through grit and rust to free up seized threads. Joker 440 also has a dielectric effect so it's ideal for preventing corrosion on battery terminals. It stops squeaking on all moving parts and is safe on plastics. Use on derailleur pivot points and cables to reduce friction and increase performance.
