WARNING Danger from falls and accidents
The use of bicycle racks can damage bicycle parts which are relevant to safety. The failure of these parts
can lead to dangerous riding situations, falls, accidents and material damage.
• Transport this bike only inside other vehicles. Secure the bike to prevent slipping, e.g. through the use of
tension belts.
• Protect your bike, e.g. by covering it against damage from sharp edges and other objects.
• No other items may be placed on the bike during transport.
• The bike must not be clamped into car transport systems (roof racks, rear or interior carrying devices
etc.).
• Front and rear wheel and the saddle post with saddle may be removed for transport if they are fitted with
quick-release axles. Remove these parts only if you are sure that you can install them again correctly.
See also section 8.6, Operating the clamping systems for wheels and the saddle post.
For transport in car interiors you can remove the wheels of your bike if they are mounted with a quick-release
or thru axle, as well as the saddle post.
NOTE:
If your bike is transported inside the motor vehicle, exposure to direct sunlight may cause the tyres to burst or
come off the wheel rim.
Let the air out of the tyres before transport and inflate them again after transport (see section 15.5.1, Changing the
inner tube and tyre).
13.1 Dismantling and installing wheels
For transport in car interiors you can remove the wheels of your bike if they are mounted with a quick-release
or thru axle.
WARNING Danger from falls and accidents
Incorrectly installed wheels can lead to dangerous riding situations, falls and accidents. Check that the
wheel is correctly mounted before you use your bike again.
• Check that the front wheel is positioned in the centre of the front wheel fork.
• Shake both wheels strongly at right angles to the direction of travel.
– The wheels must not move in their mounting.
– No cracking or grinding noises should be heard.
• Check whether the quick release lever or thru axle is correctly closed, see section 8.6, Operating the
clamping systems for wheels and the saddle post.
• After installation, carry out a check in accordance with section 7.8, Inspecting the brakes.
WARNING Danger of burns
After long downhill rides it is possible that bicycle rims and brake discs will become very hot.
• Immediately after a downhill ride you should not touch the rims or brake discs.
• Allow the rims and brake discs to cool down for at least 10 minutes before you touch them.
• In order to check the temperature, lightly tap with your bare finger very briefly on the braking surface of
the rim and brake disc. If after the above period it still feels hot, wait a few minutes and repeat the test
until the braking surface has completely cooled down.
WARNING Danger from body parts being drawn in and shearing forces
Rotating wheels can injure hands and other parts of the body.
• Press the corresponding brake before starting work on the wheel. It must no longer be possible to turn
the wheel.
WARNING Risk of brake failure for rim brakes
The brake blocks may be twisted by coming into contact with the tyres during removal and installation.
• After installation of the wheels, make sure that the brake blocks are in the correct position (see section
7.8.4, Checking the rim brake with cable (MTB version) and 7.8.5, Checking the rim brake with cable (racing
bike version)).
• If they are not in the correct position, contact an approved workshop immediately.
NOTE:
If your bike has disc brakes, please use the enclosed transport locking devices provided for transport after re-
moval of the wheel. Only remove these immediately before installing the wheels again.
• Hydraulically-operated brakes should not be operated under any circumstances if the wheels are removed.
The brake pistons might be pushed too far out.
Please proceed in the following order:
1. Dismantle the front wheel
2. Dismantle the rear wheel
3. Install the rear wheel
4. Install the front wheel
5. Check the tightness of the wheels as described in section 7.1.1, Checking the position and tight fit.
6. Check the function and installation of the breaks in accordance with section 7.8, Inspecting the brakes.
In many cases it is sufficient to remove only the front wheel for transport. In this case you do not have to
comply with the instructions for installing and removing the rear wheel.
13.1.1 Dismantling the front wheel
1. If your bike has a hub dynamo (see table in section 4.1, Types, categories, ranges) or has been retrofitted
with a hub dynamo: release the plug connection between the dynamo and cabling.
2. Open your rim brake in accordance with section 13.1.5, Opening and closing the brakes.
3. Open the lever of your quick-release or thru axle according to section 8.6.1.1, Opening the quick-release
axle or 8.6.2.1, Opening the thru axle.
4. Pick up your bike with the handlebars and pull the front wheel out of the fork ends of the front-wheel
fork.
5. If your bike has a disc brake, insert the enclosed transport lock into the brake pistons.
6. Place your bike carefully on the ground with the fork ends.
