• The “H” screw (High) controls the limit for the largest cog.

4. Adjust the Low Limit Screw (L)
With the chain on the smallest chainring and the smallest cog in the rear cassette, check the derailleur’s position. The derailleur should be close to the smallest cog without making contact. Use a 2.5mm Allen wrench[paid link] to adjust the low limit screw (L). Turn the screw clockwise to move the derailleur inward (towards the bike frame) and counterclockwise to move it outward.

After each adjustment, shift through the gears to check that the derailleur moves freely and does not overshoot the smallest cog. The chain should move smoothly without skipping.

5. Adjust the High Limit Screw (H)
Next, shift the chain to the largest chainring and the largest cog on the cassette. The derailleur should align close to the largest cog without overextending. Use the same 2.5mm Allen wrench to adjust the high limit screw (H). Turning the screw clockwise moves the derailleur inward, while turning it counterclockwise moves it outward.

Test the shifting performance again to ensure smooth transitions between the gears and prevent the derailleur from overshooting the largest cog.

6. Test for Smooth Shifting
After both limit screws are adjusted, test the bike by shifting through the entire range of gears. Pay close attention to any signs of skipping, hesitation, or noise. If the derailleur is not shifting correctly, recheck the limit screw settings.

7. Fine-Tune and Double-Check
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.
