Check And Adjust Tyre Pressure - BERG vertex series User Manual

USING SPD-SL PEDALS:
We recommend reading the information provided by the manufacturer of your pedals before use.
The following points work merely as an example of general use. Different pedals may operate differently. Please see the manufac-
turer's information on the pedals for more information.
Please contact your retailer for more information about maintenance and use.

CHECK AND ADJUST TYRE PRESSURE

Do not exceed pressure limits set out by the manufacturer and listed on the sides of the tyres.
It is essential to use the correct tyre pressure to maximise the wear resistance of the tyres.
Using a pressure below or above the limits set out by the manufacturer may result in property damage and personal injury.
Use the following table only as a general pressure guide (pressures indicated on the sides of tyres should match the pressures
shown in the table).
MOUNTAIN BICYCLE - 40-65 psi / 2.6-4.5 Bar
ROAD BICYCLE - 110-125 psi / 7.6-8.5 Bar
CITY/TREKKING BICYCLE - 70-90 psi / 4.8-6.2 Bar
HYBRID/CYCLOCROSS BICYCLE - 60-100 psi / 4.1-6.9 Bar
BMX - 35-50 psi / 2-3.45 Bar

CHECK AND ADJUST THE QUICK RELEASE LEVER
The quick release mechanisms hold the wheel in the correct position by pressing them onto the frame or fork.
They are also used on the seat clamp, using the same operating principle.
If in doubt, please contact your retailer.
Follow these steps to adjust the mechanism.
CLOSED POSITION
1. Turn the lever to the open position so that the curved part is in the opposite direction to the bike.
2. While holding the lever with one hand, tighten the fixing nut until it stops.
3. Turn the lever to the closed position. When the lever is halfway to the closed position, you should feel some resistance to move
forward from that point. If the resistance is not significant, open the lever and tighten the fixing nut clockwise.
4. Continue to turn the lever to the closed position so that the curved part of the lever faces the bicycle.
5. The wheel is safe when the fixing parts of the quick release lever begin to reach the surface of the bicycle's frame/fork.
6. Bear in mind that the quick release mechanism is the same when readjusting the seat post.
7. Place the bicycle in an upright position using the footrest for support. If you manage to fully close the quick release lever without
using your fingers in the fork blades to rotate it, and if the lever does not leave a clear imprint in the palm of your hand, then there
is insufficient tension. Open the lever, turn the adjustment and try again. The secondary restraint features do not make up for the
correct tightening of the quick release lever. If the quick release mechanism is not tightened correctly, the wheel may become slack
or loosen up, which would cause you to lose control and fall, causing serious injury or even death. With regards to the rear wheel,
the procedure is similar, although you must ensure the chain is put at the gear at which it was when the wheel was dismounted
(check the speed dial display).
SUSPENSION ADJUSTMENT
There are several types of suspension systems that cannot be dealt with individually in this manual.
If you have any questions on adjusting your suspension please consult your retailer.
Note: A suspension system should only be installed or checked by a specialist. Consult your retailer if you wish to schedule a revision
on your suspension system.
ADJUST FRONT SUSPENSION (FORK):
Before adjusting your suspension, you should test the brakes, steering and wheel fastening systems.
These should be fully functional for a proper suspension fit.
Look for gaps, noise or vibration. To adjust your suspension fork, you should proceed to adjust the SAG.
SAG is the compression travel produced by the suspension along with your weight on the bicycle.
You should adjust the SAG measuring the travel performed by the fork when supporting your weight on the bicycle. The ratio of
compression travelled against the total travel of the fork should be around 15% and 25%.
To adjust the fork compression, you should tighten/loosen the preloaded spring mechanism. This mechanism should be set on top
of one of the fork arms and should be clearly identifiable.
Tighten the adjustment to increase the preload and thus decrease the value of SAG.
Perform the reverse procedure if you wish to increase the amount.
ADJUST THE REAR SUSPENSION:
SAG adjustment on the rear suspension is performed similarly to the front fork.
Place your weight on the bicycle and measure the compression of the spring/damper. The ratio of compression travelled against
the total spring/damper travel should be around 15% to 25%.
To adjust the preloaded spring, you should tighten/loosen the adjustment plate.
If your bicycle is equipped with an air operated damper you should regulate the air pressure inside the piston using a special sus-
pension pump.
If you increase the pressure, it will decrease the amount of SAG and vice versa.
Note: The adjustable air operated shock absorbers are very sensitive and should only be adjusted by a qualified technician.
Please contact your retailer if you wish to adjust your air operated suspension.
