Headset
Although the bearings of a headset don’t rotate
as frequently as the other bearings on a bike, they
are among the most important, as they control the
accurate steering of a bike. A loose headset can
quickly damage a bike making it harder to control.
Check the headset regularly for smooth rotation. To
check headset tightness, rock the bike back and forth
or raise the front wheel a little then drop it down.
If you feel a knocking or looseness, the headset
or stem is probably loose. There are two types of
headset – a Scoot beginner bike uses a conventional
headset, adjusted with headset spanners.
Adjustment of the headset
Conventional headsets have two threaded nuts that
tighten and lock the headset bearings. The handlebar
stem, which fits inside the fork (and headset) is
totally separate component and is not involved in the
headset adjustment procedure.
Headset adjustment needs special headset spanners.
When set correctly, the headset should remain
adjusted for some time and given the relatively high
cost of the spanners, you might want to leave this
job to your dealer. However if you intend to be fully
equipped, it is best to get the Ridgeback stockist to
show you the correct way of adjusting the headset
when you buy the spanners. The idea is to tighten the
lower nut so that the play in the bearings is taken up,
but not so tight that the fork will not turn freely. The
top locknut is then tightened onto the lower one to
keep it in place.
Handlebar Stem
The stem of a Scoot beginner bike is adjustable for
height and the shape of the handlebars allows further
position adjustment when rotated back or forth in the
stem clamp. Both of which can easily be adjusted
if required using a 6mm allen key. The handlebar
should be positioned to allow the child to sit upright
in a comfortable and confident position with easy
access to the brake lever.
A loose stem can cause a serious accident
– ensure that any looseness here is resolved
before the bike is ridden, and consult a
Ridgeback stockist before riding if there is
any doubt that the stem is done up correctly.
A loose headset will cause damage during
use however it is not safety-critical.
How things work Simple maintenance
V-Brakes
A Scoot beginner bike is equipped with ‘direct pull’ or
‘V’ brakes. Small hands cannot provide much braking
power but learning to operate a brake is a vital safety
skill, and the braking power provided will quickly slow
a young rider down.
To disconnect the brakes (to remove a wheel for
example), you need to release the curved metal tube
(the lead pipe or noodle) from the slotted retainer
connected to the brake arm b. Grab both brake
arms with one hand and squeeze the brakes on to the
rim. There should now be enough slack in the cable
to unhook the lead pipe from its retainer callowing
the brake arms to move apart for easy wheel removal
- if not, use the barrel adjuster aon the brake lever
to add a little slack, but remember to take up this
slack at the barrel adjuster before riding.
A fully functioning and safe braking system
is vital to safety – please ensure you read
this section and if in doubt consult your
local dealer.
The brake pads on V brakes have grooves in them
to clear water from the rim. The pads must be
replaced before the pad is worn to the bottom of
these grooves. Most pads can simply be unbolted
and replaced. When unbolting pads to replace them,
be sure to keep the many washers and shims in the
correct order. Slip these on to the post of the new
pad. Hold the pad flat against the rim and tighten
up the allen bolt. Double check the pad hits the rim
squarely without overlapping the edge of the rim and
give the allen key fixing bolt one final turn or partial
turn to ensure pad is totally secure.
To reconnect the brake, squeeze the brakes against
the rim and hook the lead pipe back into the retainer.
Make sure that the lead pipe is correctly located and
that the outer cable is properly seated in the brake
lever (the outer cable can often ‘pop out’ of the brake
lever during the disconnecting of the cable at the
brake arm end of the system).
The brake pads on a Scoor beginner bike will have a
far longer lifespan than those used on an adult’s bike.
As the pads wear, you can take up additional cable
slack with the barrel adjuster on the brake lever.
Keep an eye on the pads though, make sure they’re
not too worn and that they still hit the rim squarely.
Uneven pad wear may create ridges that can cause
the pad to stick or jam against the rim - it only takes
a moment to correct it and it may avoid problems
later. Use quality brake pads for replacement.
