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 V-BRAKES
Correctly adjusted brakes - after pressing both brake levers simultaneously on 2/3 of their
travel, brake pads, they must be in their entire working surface in contact with the side walls
of the rim. After releasing the lever, the pads should return to their original position.
1. Adjust the brake pads using the screw 1 (fig). The blocks must be adjusted so that the
entire surface of the brake pads during the braking touches the side walls of the rim.
Rubbing against the tire is unacceptable.
2. The tension adjustment of the brake cable is
made via screw 2 (fig). It is necessary to slightly
loosen the screw 2 so that the brake cable can be
adjusted freely, after the brake cable has been
correctly adjusted, it should be tightened again.
3. Adjust the brake arms by means of a screw 3
tightening or loosening the screw 3, position the
arms so that they are symmetrically aligned with
the wheel.
4. Brake pads should be regularly adjusted, and when rubbing out brake pads should be
immediately replaced with new ones.
6.8 CRANKSET
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.
The axles of the pedals should be sufficiently
tightened to the crank arm. Incorrect tightening
will loosen the threaded connection, which will
consequently destroy the thread of the pedal and
crank! The right pedal axis has a right-hand thread
marked "R". The left pedal axis has a left-hand
thread marked "L".
