Once the limits feel good, perform a final check by shifting into all gears while pedaling under load. This will ensure the derailleur operates smoothly even when force is applied. If needed, make minute adjustments to the limit screws to fine-tune the derailleur’s position for the most precise shifting performance.

Troubleshooting Common Issues with Limit Screw Adjustments

• Chain drops off the smallest cog: This is usually caused by the low limit screw (L) being set too far out, allowing the derailleur to push the chain beyond the smallest cog. Tighten the low limit screw (L) by turning it clockwise until the derailleur aligns correctly.
• Chain overshoots the largest cog: If the derailleur is pushing the chain into the spokes or beyond the largest cog, the high limit screw (H) is set incorrectly. Turn the high limit screw (H) clockwise to pull the derailleur inward and prevent overextension.
• Shifting is sluggish or inconsistent: If the shifting is not smooth after limit screw adjustments, check your cable tension and ensure the derailleur hanger is properly aligned. Misalignment in the derailleur hanger or poor cable tension can lead to sluggish shifting, even with perfect limit screw settings.
