inner face of the chain guide and the chain can be set to a
maximum of half a millimetre using the adjusting screw on
the shifter on the handlebar
(see fig. 60, chapter 6) .
Adjusting the rear derailleur top gear
Turn adjusting screw (fig. 69, A) to adjust the top gear.
Ensure the chain is on the outermost sprocket and turn the
adjusting screw until the jockey wheel, viewed from the
rear of the bike, is directly in line below it.
Adjusting the rear derailleur bottom gear
Turn adjusting screw (fig. 69, B) to adjust the bottom gear.
Ensure the chain is on the innermost sprocket and turn
the adjusting screw until the jockey wheel, viewed from
the rear of the bike, is directly in line below it. Now check
second gear. If the chain is interfering with an adjacent
sprocket, this can be adjusted out using cable adjusting
screw
(fig. 69, C) . In some versions the adjusting screws
are in a different position on the derailleur. Adjustment is as
described above.
NB
The chain should follow a straight line as far as possible.
This means that shifting to some combinations is pointless
and causes needless wear to the chain, chainrings and
sprockets. If the chain is running on the smallest chainring
at the front, avoid running it on either of the two smallest
sprockets at the rear. If the chain is running on the largest
chainring at the front, avoid running it on either of the
two largest sprockets at the rear. Combining the middle
chainring at the front with the smallest or largest sprockets
at the rear is also inadvisable
(see fig. 70) .
6.5 Derailleur gear maintenance
The cassette transmits the motion from the to the rear
wheel, causing it to rotate. On our derailleur bikes
this cassette can consist of 8, 9 or 10 sprockets. An
accumulation of dirt or improper chain tension can cause
rapid wear in these sprockets. Should this be the case, it
can cause chain damage or annoying “skipping”. In this
situation there is nothing for it but to have the cassette
replaced.
