SIS derailleur gear adjustment
To help ensure that your derailleur gears work efficiently and to prolong their life, they must be kept
clean and free from excess dirt and should be properly lubricated.
The next few pages and diagrams show the basics of how to adjust derailleur gears. If you have any
problems you should contact us before riding.
Rear derailleur
High and Low adjustment (the rear wheel must be free to rotate)
The idea is to find the position where the shift will always occur, but there is no possibility of
accidentally over-shifting the rear derailleur into the spokes.
This will not only be expensive but will cause the rear wheel to lock up…with potentially serious
consequences.
We recommend that you confirm the gear operation whilst cycling at low speed on a quiet road.
Turn the low adjustment screw so that the top jockey wheel moves to a position directly below the
largest sprocket. Turn the top gear adjustment screw on the gear mechanism so that, looking from
the rear, the top jockey wheel is below the outer line of the small sprocket.
Check that the chain cannot accidentally over-shift the small sprocket.
