6.4 WHEELS

Properly adjusted wheels should rotate slightly and smoothly, without jerks, perceptible
slack. In the case of loosening in the wheel hub, it must be eliminated by adjusting. In order
to adjust the wheel, you must have specialist tools, therefore, if a fault is found, please go
to an authorized service point.

6.5 TIRES

For tires, the pressure range specified by the manufacturer must be observed on the side
of the tire (pressure unit indicated on the tires 1000 kPa = 14.22 P.S.I = 1 bar = 1 at). The tire
should be placed in the direction indicated on its side (the arrow shows the direction of
rotation). The tire should not have any deformations or cracks and should adhere to the rim
in parallel. After finding out that the tire has any of the defects, immediately go to an
authorized service point.

6.6 SPOKES

Spokes in wheels should be evenly stretched. The spokes loosened during the bicycle's
operation may cause radial and axial runout of the wheels or rupture of the spokes, which
affects the service life of the rim and hub bearings, as well as negatively affects the braking
performance. These irregularities should be removed at service points.

6.7 BRAKES

Bicycle disc brakes are more efficient than v-brakes. They do not
require paying much attention, but from time to time there may
be necessity of adjusting the distance between the brake pads
and the disc. In mechanical brakes, the distance between the
pads and the disc is adjusted in such a way as to equalize the right
and left distance between the brake disc and brake pads. If the
brake pads are worn, the clearance on the outside and inside
must be evenly adjusted to prevent the brake pads from touching
only one side of the disc.

6.8 CRANKSET

In addition, adjust the cable so that the rest is less than 20
mm. If the rest of cable is longer, the end of the cable may
get stuck in the disc brake rotor, which could block the
wheel while cycling and seriously injure yourself.
The crank mechanism with cranks mounted on the axis with
the screw requires systematic control. The contribution of the
crank mechanism together with the screw-in bowls, showing
excessive clearance, is regulated by tightening the main
screw with an Allen wrench. Using a bicycle with a loose
crankset causes indentation of the crank seat and its
destruction.
