To adjust high gear:
-Turn the adjustment screw marked ‘H’ until the top guide pulley lines up with the outside edge of the outermost sprocket. Setting the guide pulley beyond the outside edge of the sprocket will cause the chain to come off when pedalling. Setting the guide pulley too far toward the larger cogs may prevent the chain wheel shifting onto the small sprocket.
-
-Position the right shifter all the way to the low position (fully forward for downtube shifters, fully back on MTB top bar shifters).
-Ensure that the derailleur cable is taut. If too much slack is detected, loosen the cable fixing bolt, pull the cable taut, and
To adjust low gear:
- Turn the adjustment screw marked ‘L’ anti- clockwise until you can shift the chain onto the largest rear sprocket and the smallest chainring.
-Move the shifter until the derailleur guide pulley and the sprocket are aligned.
-Rotate the ‘L’ adjustment screw until it meets resistance. The derailleur will move outward and throw the chain off the sprocket when pedalling if the screw is turned in too far. Conversely, if the adjustment stops the derailleur moving far enough, the chain may not engage in low gear.
-Test the adjustment by rapidly shifting the chain up and down the freewheel.
Note: On bicycles equipped with indexed derailleur systems (SIS) the chain should pause when moving into each position. If the chain does not move easily onto the large sprocket while on the small chainring, screw out the ‘L’ adjusting screw slightly.
If the small sprocket is difficult to engage with the chain on the large chainwheel, screw out the ‘H’ adjusting screw slightly.
