Installation and care tips

1. Inspect the existing chain ends and ensure you’re replacing with a single EK 420 O-ring rivet link that matches your chain size.
2. Align the chain on a stable stand and position the rivet link so the rivet hole lines up cleanly with the chain plates.
3. Use a compatible chain rivet tool to drive the rivet pin to the recommended depth, ensuring the rivet is flush with the link plates.
4. Verify smooth motion by rotating the rear wheel and checking for even tension across the link and sprockets.
5. Lubricate the chain after installation to maximize the O-ring seal’s effectiveness and reduce friction during the break-in period.
