Spring tension of the seat post
Gazelle has outfitted many models with a suspension system in the
seat post. The spring tension is set at the factory to medium. If you
want to change the spring tension, you must remove the seat post
from the frame (fig. 50).
The spring tension can be adjusted on the bottom side of the
seat post using a 6 mm Allen key (fig. 51). Turning it clockwise will
increase the spring tension, turning it anti-clockwise will decrease
the tension. If the seat post has sideway play, it can be fixed by
turning Allen bolt (B) (fig. 52).
Sideway play of the Seat Switch is readjusted with help from
adjusting ring (C). When readjusting, make sure that the post still
has suspension (fig. 52).
Maintenance of the front and rear fork’s suspension system
Both the front and rear suspension are ingenuously constructed.
Therefore never use a high-pressure cleaner. This may cause
leakage within the suspension system. The best way to keep the
suspension units clean is by using a moist, soft brush.
The suspension’s up and downward movement can cause dirt and
moisture to enter the mechanism, thereby diminishing its action.
Therefore, the arms of the fork should be cleaned regularly, also
beneath the rubber parts. After cleaning, Teflon-containing oil
should be reapplied to them (fig. 53).
Disc brake maintenance
The disc brake consists of 2 movable brake pads. If the braking
power is diminishing, you must go to the dealer. This can indicate
the presence of air in the hoses. Stop riding directly and go to your
dealer (figs. 54 and 55).
If you find oil traces on the levers or hoses, go directly to your
dealer. This can indicate leakage. Check before every ride for signs
of possible leakage.
Brake pads must be replaced if they are worn down to half a
millimetre.
Caution: The brake discs shouldn’t get oil, grease or paint wax on them!
Gear hub adjustment
If your bike is fitted with a Sturmey-Archer 3-gear hub, put the
shifter in the middle position. Then briefly move the pedals up and
down so as to be sure that the hub is in the middle position as well.
Remove the back part of the chain case (see page 40/41). Then
loosen nut (S) and twist the sleeve (H in fig. 56). The end of the
indicator rod (C) must be in line with the end of the axle. You can see
this through the hole in the axle nut (fig. 57).
Subsequently, retighten nut (S). By shifting a few times and seeing
whether the adjustment returns to the original position, you can
check if the adjustment is correct. If everything is in order, you can
click the back part of the chain case back in its place.
