RIMS
Check before each ride if wheels are centred correctly and rims are not damaged. There could
appear grooves and cracks by using bicycle or they could be caused by blast. Side areas of
rim are getting worn up by braking. There is security system on each rim side which indicates
deformation on side of rim. Bent side area of rim is mark of worn up which causes self-acting
braking. Riding such damaged rims is dangerous and damaged rim must be replaced!
TIRES
Never ride on over or under inflated tires. Respect recommended pressures, which are shown
on sides of each tire. Calculation of pressure measurement units mentioned on tires follows:
100kPa = 14.22 P.S.I. = 1 bar = 1 at
In case of puncture replace always damaged tube by new one with the same parameters like the
old one. Parameters are marked on each tube or on sides of tire.
FRAME AND FORK
Check regulary if the frame and fork of your bike are not damaged. Damage of the frame or fork
is mainly caused by accidents and falls. Stop using such damaged frame or fork, otherwise you
risk serious injury!
SUSPENSION FORK
If bicycle is equipped with suspension fork respect following instructions:
COMPRESSION SETUP
1. SPRING FORK
Fork compression setup unit is placed in upper part of right fork leg. Fork with suspension lock
out (Speed Lock) has compression setup unit placed on left fork leg. Turn compression setup
unit clockwise to set up higher rigidity of fork, by turning it counter clockwise the rigidity of
fork decreases.
2. AIR SUSPENSION FORK
Air suspension fork compression is setup by pumping up air into fork air chamber. Valve for
pumping up air is in upper part of left fork leg. Unbolt valve cover and pump up till the
needed pressure according below chart is reached. Use only high pressure pumps for forks
with manometer.

Recommended pressure rates for pumping up
SR SUNTOUR air suspension fork:
rider weight air pressure
36 kg 51 PSI
45 kg 64 PSI
54 kg 77 PSI
64 kg 91 PSI
73 kg 104 PSI
82 kg 117 PSI
91 kg 130 PSI
100 kg 143 PSI
IMPORTANT WARNING
Maximum allowable pressure is 150 PSI!
WARNING
Be careful when connecting pump hose with fork air valve to avoid valve thread damage. Use
microvalve on pump under manometer to precise pressure setup. A bit of air can run away
from valve when disconnecting pump. Check with manometer how much of air run away and
pump it up again to the fork. Finally close valve with cover.
FORK COMPRESSION LOCK OUT - SPEED LOCK
Some forks have hydraulic lock out system. Fork lock out enables reduce fork teetering what
increases pedaling efficiency when riding uphill or sprinting.
Fork's lock out setup unit is placed in upper part of right fork leg. Lock out is operated by blue
lever with Speed Lock tag. Turn Speed Lock clockwise for lock out, turn counter clockwise to
unblock compression and fork will work in normal mode.
IMPORTANT WARNING
Fork compression lock out is intended for use when riding in less difficult terrain. It is
necessary to unblock fork when riding in rough terrain otherwise fork lock out system
could be damaged!
FORK MAINTENANCE
CLEANING / LUBRICATION - regular maintenance is crucial for proper fork operation, mainly
maintenance of friction areas between outer and inner fork legs. Dust seal and gasket which
keep friction areas from contamination must be not damaged and must protect whole
