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.

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
