WD-40 Company 390234 Bike Chain Lubricant 6 Oz

Product Description

The WD-40 COMPANY 390234 is an all-conditions bicycle chain lubricant formulated to perform in dry, wet, and variable weather environments. Delivered as an aerosol spray, the product applies quickly and penetrates chain links to reduce friction and prevent squeaking. The formula is wax-free, which eliminates the sticky residue buildup that commonly accumulates inside chain links and drivetrain components over time. Built-in corrosion inhibitors provide ongoing chain protection between service intervals. Each can contains 6 oz of lubricant, making it practical for shop use or field service kits.

This lubricant is suited for bicycle maintenance across residential, recreational, and light commercial settings. Bike mechanics, shop technicians, and experienced cyclists use it on derailleur-equipped drivetrains operating in varied terrain and weather conditions. Its all-conditions rating makes it a single-product solution where stocking separate wet and dry chain lubes is not practical. The aerosol format allows for precise application without over-lubricating adjacent components.

Key Features

• All-conditions formula performs in dry, wet, and mixed-weather riding environments
• Wax-free composition prevents sticky residue buildup inside chain links and drivetrain
• Corrosion inhibitors protect chain metal between applications
• Aerosol spray format enables fast, controlled application
• Reduces chain squeaking and extends overall chain service life
• 6 oz net weight per can; sold in cases of 6 units

Compatibility

Designed as an OEM-style lubricant for standard bicycle roller chains used on derailleur and single-speed drivetrains across common bicycle types.

Installation Notes

Application is typically performed by bike mechanics or experienced cyclists as part of routine drivetrain maintenance. Clean and degrease the chain thoroughly before applying fresh lubricant to ensure full penetration and adhesion. Apply the aerosol in short passes along the chain while slowly rotating the drivetrain, then allow adequate dwell time before wiping off excess. Avoid spraying onto brake rotors, brake pads, or rim braking surfaces.
