Adjusting the front derailleur
The range within which the front derailleur keeps the chain on the chainring without itself touching the chain is very small. If the chain tends to jump off the chainring, you will need to reduce the movement range in the same way as with the rear derailleur, i.e. by turning the limit screws marked «H» and «L» (a). The limit screws are adjusted by your URBAN JUNGLE dealer. They do not alter their position during normal use.
As with the rear derailleur, the cable of the front derailleur (b) is subject to lengthening which leads to a reduced precision in gear changing. If necessary, shift to the small chainring and in- crease the tension of the Bowden cable by turning the adjusting bolt through which it passes at the entry to the gear shifter (c).
WARNING
Always check after an accident whether the guide plates of the front derailleur are still parallel to the chainrings. Make sure they do not touch the large chainring which would block the drive. Risk of accident!
Adjusting the front derailleur is a very delicate job. Improper adjustment can cause the chain to jump off, thus interrupting the power train. This can cause a fall!
Do a test ride in a place free of traffic, after adjusting the gears of your bicycle.
