Some racing bikes are fitted with so-called
tubular tyres. In such cases, the inner tube is
sown into the outer tyre. Outer and inner tubes
are then glued on to the special rim during
assembly. The assembly instructions issued
by the tyre, glue and rim manufacturer must
be followed.
Refer to the instructions in 7.1.3.
Rim reflectors may be fitted on bikes which
conform to the StVZO specifications.
Checking the assembly
Vigorously shake both wheels back and forth,
perpendicular to the direction of travel.
- The wheels must not move in the clamp.
- The quick release/thru-axle must be closed/
tightened.
- There should be no cracking or grinding sounds.
Contact your dealer if you discover any defects
when checking the assembly.
Checking the rims
Risk of personal injury and material damage!
Worn rims and/or big wobbles in the wheel can
lead to dangerous riding situations, crashes,
accidents and damage to the bike.
Worn rims must be replaced; if there is a wobble in
the wheel, it must be repaired!
Risk of personal injury and material damage!
For rim brakes: dirty rims may reduce the braking
force.
Dirty rims must be cleaned immediately.
Risk of personal injury and material damage!
Using a bike which is not roadworthy can lead to
dangerous riding situations, crashes, accidents
and damage to the bike.
Also take into account the possibility that your
bike may have fallen over when left unguarded or
that others may have tampered with it.
- Before every ride, check that your bike is
roadworthy.
- Remember the condition of your bike upon
purchase so you can easily recognise at a later
stage whether any parts of the bike deviate
from the correct state (it is sometimes a good
idea to take photos).
- Immediately contact your dealer if you find that
the condition of your bike deviates from the
correct state.
- Only ride this bike again once the dealer has
completed the necessary repairs.
Visually inspect the whole bike:
- Make sure all screws are tight
(see Section 1.2.4).
- Check the whole bike for tears, cracks, deep
scratches or other mechanical damage.
Contact your dealer if you discover any defects
during this visual inspection.
Checking the wheels
A wheel is made up of the following components:
- hub
- disc brake (optional)
- sprockets or sprocket cassette (rear hub only)
- spokes
- rim
- tubeless tyre (without inner tube) or clincher/
folding tyre (with inner tube and rim tape)
1 Have your dealer check that the bike is
assembled correctly and confirm that your bike
is roadworthy.
2 Have your dealer adjust the saddle position so
that it is at the right height for you.
You can fine-tune and make minor adjustments
yourself, as described in Sections 8.2 and 8.3.
3 Only use your bike once your dealer has
explained the technical aspects of your bike.
4 Protect your bike with spray wax, see Section 12.
5 Read Sections 6 and 7 before riding your bike for
the first time.
Risk of personal injury and material damage!
Using a bike which is not roadworthy can lead to
dangerous riding situations, crashes, accidents
and damage to the bike. The same risks apply if
you are not yet familiar with your new bike and
do not know how to use it properly.
- Familiarise yourself with your bike before riding
it for the first time. Make sure you know which
brake lever operates the front brake and which
operates the rear brake (see Section 8.5).
- Modern brakes have a very strong braking
force. This means that when the brake lever
is squeezed too far, the respective wheel
can become blocked and thus can cause an
accident. Practice using the brakes on safe
terrain.
- For new rim or disc brakes, or after replacing
brake pads or disc brake pads (for disc brakes),
it takes a while (running-in period) before the
brakes reach their maximum braking force.
Bear in mind that the braking distance will be
longer at first.
- If your bike is equipped with optional clipless
pedals (Isaac Cycle bikes are not fitted with
pedals as standard) which securely fasten the
shoe to the pedal:
Practice clicking and unclicking your shoes onto
the pedal before use.
Clipless pedals are not safety pedals!
- If you need to remove the seatpost and front
and/or rear wheel for transporting your bike,
refer to Sections 11.1 and 11.2.
