3. Front fork & head tube
suspension
Some Gazelle bikes are fitted with a suspension front fork.
There are two types of suspension: front fork suspension
and internal headset suspension. You can read how to
set up both of them here. With front fork suspension, the
suspension mechanism is located in the front fork legs; if
you have internal headset suspension, then the suspension
mechanism is built into the steerer tube.
3.1 Set-up
Front fork suspension
You set the stiffness of the front fork suspension with
the thumbwheel
(fig. 13, A) on the front fork. You turn it
clockwise to make the suspension stiffer, anticlockwise
to make it softer. Take care to ensure that the tension is
the same both sides. If necessary, you can achieve this by
zeroing both sides. If you then see to it that you adjust both
sides by the same number of turns, you will be sure that the
tension is equal in both suspension units.
Internal headset suspension
You set suspension stiffness by means of the small bolt
under the head tube, between the two legs of the fork
(see
fig. 15) . You turn it clockwise to make the suspension stiffer;
to make it softer you turn it anticlockwise. Whenever you
want to adjust the internal headset suspension, you will
need to slide the rubber sleeve down in order to expose
the adjustments system
(see fig. 14) . Unscrew nuts (A) with
a 14 mm open-ended spanner. Tighten the 4 screws (B)
using a 6 mm Allen key to remove any play. Tighten each
opposite pair of screws
(B) together. Repeat until all play
has been eliminated. If, by any chance, the screws (B) are a
little too tight, unscrew them alternately so as to eliminate
excessive friction. Ensure the 4 screws
(B) are tightened
evenly. The fork is adjusted correctly if there is no play
while the fork is still able to move smoothly. Tighten all nuts
(A) to prevent the bolts from coming loose. Refit the rubber
sleeve to seal off the fork.
