Lubrication
Lightly oil all the pivoting points of the front and rear derailleurs at least every month. Any excess oil should be wiped off to prevent dirt entering into the mechanisms. Clean and apply a thin layer of grease to the shifting cables every six months,
or whenever new cables are fitted.
Adjustment – Rear Derailleur
If your bicycle is fitted with a SIS derailleur system, fine turning of the SIS mechanism will be the most common rear derailleur adjustment you will need to make.
To fine tune the SIS rear derailleur:
-Raise the back wheel of your bicycle off the ground (to enable you to rotate the pedals forward) and set the shift lever on SIS mode.
-Change the gears from top to second top gear and observe the chain’s response.
If the chain will not move to second gear, turn the cable adjusting barrel
-Spin the pedals and with the chain still in second gear, turn the adjuster
If after completing the above process further adjustment is still required, stand behind the bike. Shift the chain to the smallest rear cog and the largest front chainwheel, and loosen the cable fixing bolt.
Also, check whether your SIS derailleur system is fitted with an additional adjustment screw to set the guide pulley as close as possible to the sprocket. If so, shift the chain onto the small cog and adjust until there is no sound of rubbing or fouling when the pedals are turned backwards.
Whatever type of derailleur system is fitted to your bicycle, the alignment of the chain, the rear sprockets, and the derailleur pulleys need to be inspected whilst standing behind the bicycle. Based on your findings, adjustments to high or low gear may be necessary.
