At its coronary heart lies the pivot mechanism – this half permits the cage to swing backwards and forwards. Managed by pressure from a cable related to your left-hand shift lever, it determines how far and the way laborious your derailleur strikes. Subsequent are restrict screws marked ‘L’ and ‘H’. They’re important as a result of they forestall your chain from dropping off both aspect of your crankset by limiting how far left or proper the cage can transfer.

Lastly, you will discover there’s typically a small screw or set of screws concerned in adjusting cable pressure; these fine-tune how tightly or loosely your shifter cable pulls on the derailleur.

• Loosen the clamp bolt, permitting you to maneuver it up or down.
• Align it so there’s about 1-3mm of clearance between the most important chainring enamel and backside fringe of outer plate when considered immediately from above.
• Alter its angle in order that the chain runs parallel to this outer plate when trying from behind.

Subsequent concentrate on restrict screws which management how far the derailleur can transfer:

• The ‘L’ screw adjusts inward motion in direction of smaller rings; tighten it till simply earlier than chain rubs in opposition to inside cage then again off barely.
• For outward motion, use ‘H’ screw; shift to largest ring plus one rear gear increased than lowest cog (so as to add slight pressure) then alter till there’s minimal clearance with out rubbing.

Lastly dial in cable pressure:

• Retighten anchor bolt making certain cable is taut however not pulling excessively.
• Shift by gears checking for snappy transitions; if essential, make fine-tuning changes utilizing barrel adjuster on shifter or down tube.
