The Park Tool CL-1 Synthetic Chain Lube (4 oz. / 118 mL) is a premium, high-performance general-purpose lubricant designed to keep bicycle drivetrains running smoothly. Formulated with a high-tech, proprietary blend of oils enhanced with PTFE (Teflon), it performs exceptionally well in both wet and dry trail conditions.

Key Features

• PTFE Anti-Friction Barrier: Infused with polytetrafluoroethylene (PTFE) to significantly reduce mechanical friction, eliminate annoying drivetrain squeaks, and lower overall component wear.
• Moisture Displacement: Formulated to deeply penetrate pin rollers and link plates, actively pushing out trapped water and moisture to seal out rust and corrosion.
• Multi-Purpose Fluidity: While optimized as a drip-style chain lubricant, its light viscosity makes it highly effective for lubricating brake/derailleur cables, inner housings, spoke nipples during wheel builds, and frame pivot points.
• Universal Drivetrain Safety: 100% compatible with all varieties of bicycle chains, from single-speed city cruisers to high-performance 12-speed road and mountain bike drivetrains.

Usage & Application Recommendations

To maximize performance, bike mechanics recommend following this application routine:

1. Deep Clean First: Strip away old grease, dirt, and road grit using a dedicated degreaser and a chain cleaning tool before applying the lube.
2. Precision Drip: Apply one single drop of CL-1 directly onto the top of each individual chain roller link while back-pedaling the drivetrain.
3. Let Penetrate: Allow the fluid to sit for a few minutes so the synthetic blend can travel deep into the inner pins.
4. Wipe off the Excess: Use a clean, lint-free rag to thoroughly wipe off any excess surface fluid from the outside of the links. Leaving the exterior dry prevents road dust and trail grit from turning into a black abrasive paste.
   Note: Some painted frame surfaces can be highly sensitive to synthetic oil. Wipe away splashes instantly, and consider testing a hidden section of your bike frame first to avoid accidental staining.

This lubricant is an essential tool for maintaining your bike in peak condition, ensuring smooth and efficient performance in any riding environment.
