yourself with the new brakes! Modern brakes can
behave completely differently under braking than
those that you are perhaps used to. The bicycle’s
steering should not rattle under braking or exhibit
any play.
Check the air pressure in the tyres. You will nd
instructions as to the correct tyre pressures on the
sides of the tyres. Please adhere to the required
minimum and maximum pressure! If you cannot
nd any recommended pressures, 2.5 bar / 36 PSI
is a suitable pressure for most tyres. If the wheels
are thinner than 30 mm or 11/8“, the tyre pres-
sure should be lled to 4 bar / 58 PSI.
As a general rule of thumb when you are out on
a ride, you can check the tyre pressure by do-
ing the following: If you place your thumb on a
pumped up tyre, you should not be able to sig-
nicantly change its shape by applying pressure.
Check the tyres and rims. Scan them for any
damage, cracks or deformations, as well as em-
bedded particles, e. g. shards of glass or sharp
stones.
If you should nd any cuts, rips or holes, please
refrain from riding! First have your bicycle
checked over by a specialist.
Before each ride
Before every ride, please check that:
• The lights and bell are working and safely se-
cured
• The brakes are working safely and are prop-
erly secured
• The cables and ttings are not leaking if you
have a model with hydraulic brakes
• The tyres are free of foreign objects and dam-
age, and the rims are not damaged and run
true, particularly after riding off road
• The tyres have a sufcient tread depth
• The suspension components are working
properly and are safely secured
• All bolts, nuts, through axles and quick releas-
es are tight (see pages 7 and 25)
• There are no deformations or cracks on the
frame and fork.
• The handlebars, stem, seat post and seat are
both correctly and securely fastened as well as
set up in the right position
• The seat post and seat are secure. Try turning
the seat or tipping it upwards or downwards. It
should not move.
• If you are using clipless/magnet pedals, please
check that they are working properly. The ped-
als should release easily and smoothly.
• For BMX bicycles: the rotor works safely, the
handlebars are safely secured in the stem and
the axle pegs are safely secured.
If you are unsure of whether your bi-
cycle is in a sound technical condi-
tion, take it to a specialist retailer to
be checked instead of riding it!
It is particularly important if you use your
bicycle a lot, either through sports riding or
daily use, that you regularly have all the im-
portant parts checked by a specialist retailer.
Frame and fork, suspension components
and other parts relevant to your safety such
as brakes and wheels are subject to heavy
wear, which can impact the operating safety
of these parts.
If you use parts for longer than their intended
lifetime, these can fail without warning, which
can in turn lead to falls and serious injury!
Please make these checks before
continuing after a fall or if your bicy-
cle falls over!
Aluminium parts cannot be safely bent back
into shape, while carbon components can
sustain damage which is not recognisable
to the eye.
Allow the bike to be checked by a specialist
retailer.
