Chain guard
4. Fit the rear cover in place and secure it with the screw.
Chain tension
Important:
In order to function effectively, the chain must have a certain
tension/length. With use and wear, the chain begins to
stretch, so the chain tension must be checked regularly.
1. Remove the chain guard (see
Chain guard
in
the
Settings and adjustments
section).
2. Place a ruler on the ground and lean it against
the centre of the chain, between the front sprocket and
the crankset. Pull the chain upwards and measure how
much the chain moves vertically.
-
If the distance is greater than 12 mm, the chain
tension must be increased.
-
If the distance is less than 6 mm, the chain tension
must be decreased.
3. Loosen the socket
head screw
(5 mm) and the nut
(10 mm) which
holds the brake
stay in place on
the frame.
• The bicycle is equipped with a full-cover chain guard
which not only protects your trouser legs from contact
with the chain but also protects the chain, chainrings
and sprockets from dirt, grime and water.
• In order to perform certain settings, maintenance and
repairs, some parts of the chain guard will need to be
removed.
• The chain guard consists of an outer cover and an
inner cover for the chain and chainring plus a rear
cover for the rear sprocket.
1. Remove the screw from the lower half of the rear cover
and pull the cover backwards.
Important:
Make sure that the right-hand crank
arm is horizontal and that the pedal is closest to
the front wheel, otherwise there is a risk of damaging
the outer cover when it is being removed.
2. Carefully bend and detach the outer cover from
the inner cover, beginning at the rear. Remove
the outer cover.
3. Refit the outer cover in the reverse order.
-
First join the top edges of the covers together.
-
Match up the bottom edges.
-
Follow the join around the whole edge and click
the two covers together.
