TREKKING I CITY
DISC BRAKE ROTOR
Rotor status must be checked regularly. Rotor is worn out by braking which results in scratches on it.
Replace damaged rotor by new one.
WARNING
Rotor is heated by braking therefore disassemble wheels from fork or frame carefully. Hot rotor could cause
skin burns!
DISC BRAKE PADS
Brake pads are wearing out by braking effect is gradually less efficient. Possible marks that brake
pads are worn out are these: brakes are making noise while braking or you notice that brakes are less
efficient. Worn out brake pads must be replaced by new one. Your retailer recommends you suitable
brake pads.
BRAKE FLUID CHANGE
Air in disc brake system could cause reduced braking efficiency or disc brakes failure. It is necessary
bleed air from disc brake system or eventually replenish it by brake fluid.
WARNING
Disc brake hydraulic system is filled up by standard brake fluid or mineral oil. These two brake fluids can
not be mixed each other. Only recommended brake fluid by manufacturer can be used for replenishment
or brake fluid change. Brake fluid change or hose change requires experiences and special tools hence it is
recommended to visit qualified service center.
DISC BRAKE CLEANING
Disc brake rotor, pads and brakes must be kept clean. Grime rotor by oil or by other lubricant must be
cleaned immediately e.g. by benzin. When disc brake pads are impure by brake fluid it is necessary
replace them by new one.
IMPORTANT WARNING
1. Check before each ride if disc brake system is working perfectly. Press few times brake lever and check if
brake system works really properly.
2. Check regularly if all braking system screws are tight securely. Released screws could cause braking
system failure.
3. Disc brake rotor and caliper are heated up by braking. Do not touch them immediately after braking, hot
parts could cause skin burns.
4. Learn use disc brake system properly. Too much intense braking by front brake could cause downfall and
injury. Serious injuries could occur when disc brakes are not set up properly or they are not used properly.
FRONT AND REAR WHEEL
It is necessary to check and tighten regularly end nuts by which bicycle wheels are secured to the
forks. If wheels are secured by a quick release system they must be checked before each ride to be sure that
wheels are secured correctly. Lever of quick release system must be in position CLOSE. Quick release system
enables easy and fast assembling and disassembling of wheels without using tools. Check before
ride if wheels are centred in forks. Tighten quick release nut so much that lever will put up resistance
when closing. When quick release system is closed to the secured position it must push closer both
fork ends. Move quick release lever only to the sides to reach its position OPEN or CLOSE. Never turn closed
quick release system it could be damaged!
Torque tightening values:
M10 nut of hub axle
Check the wheel hubs periodicaly, mainly after ride in wet and muddy conditions. The hub axle
should rotate without any friction and loose. If it does not, even after axle's cones and safety nut set-
up, it is necessary to disassemble the hub, clean bearing rings and balls, lubricate them with a new
grease, assemble and set up the hub again. If you are not skilled enough to do that, we advise you to
contact a special bike service.
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 selfacting 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
