Intended use
Any use differing from that intended could cause an accident and result in death or
serious injury.
THM-Clavicula crank systems have been exclusively designed
- for installation on standard racing cycles, time trial and gravel.
- forthe permitted area ofapplication – see Areaofapplication , page 14.
Fundamental safety precautions
The following warnings for the THM-Clavicula component apply to all Clavicula models
(Clavicula Road, Clavicula MTB etc.), unless otherwise specified.
Forthe time being we limit the service life of your THM-Clavicula crank system to 100,000 km
or 10 years. It is imperative you contact us before continuing to use your THM-Clavicula crank
system after one of these limits has expired!
Always remember that riding a bicycle involves potential danger for the rider and other road
users, as well as for the bicycle and its components. Even if protective equipment and safety
devices are used, accidents resulting in death or serious injury can still occur.
You should therefore use your common sense and avoid any unreasonable
behaviour!

SAFETY
Assembly & Maintenance
Risk of accident caused by assembly and maintenance work which has not been
conducted in a professional manner.
- Do not overestimate your technical ability. All assembly and maintenance work
should be performed by a specialist workshop for bicycles. This is the only way to
ensure the work is conducted in a professional manner.
- Always observe all of the specified tightening torques for the screw connections.
- Only use suitable, undamaged, high-quality tools.
- Only ever use original THM components which are available from your specialist
dealer or directly from THM.
- Never make any modifications to your THM components.
- Check your crank system (incl. cranks, bottom bracket, chainwheels) to make sure
it is undamaged and working properly before every ride. Send us your THM-
Clavicula component before further use if damage is visible (cracks, fractures,
deformations, etc.) or ifyou are in any doubt about itsfunctionality.
- Check your THM components before each ride to ensure the surfaces are
completely undamaged. Send us your THM components for inspection before
further use if damage is visible (deep scratches inthe paintworkwhich extend into
the carbon structure, large abrasions, etc.), if you are in any doubt about their
functionality or if the Clavicula lettering is abraded at one or more points (wear
indicator).
- Always ensure your bicycle is maintained in a flawless condition. Care and
maintenance will prolong the service life of your bicycle and its components and
also improve your personal safety.

SAFETY
On the road
Danger of accidents due to improper behaviour or improper equipment during
riding.
- Always ride with foresight, attention and a readiness to brake.
- Adjust your speed to the prevailing conditions (traffic, weather, visibility, etc.).
- Do not use your THM components at ambient temperatures below -10°C (14°F).
- Do not exceed the maximum overall weight for which your THM
components have been approved
– see Size , page 10.
- Do not perform jumps with your bicycle as this generates an enormous amount of
force.
- Always comply with the traffic regulations that are in force in the country
where you are using your bicycle.
- When riding your bicycle you should always wear a high quality cycling
helmet (e.g. ANSI certified) thatisinexcellent condition. Yourclothing should
beclose-fitting but notrestrictive.
- Only ride your bicycle if you are in good physical condition and your
bicycle and all of its components are operating in a flawless manner.
- Ifyou are involved in a heavy fall you should not continue to ride your
bicycle. If such a case occurs, send us your THM components for inspection,
even if no external damage is visible! In your own interest you should treat
all of the components on your bicycle which have been produced by other
manufacturers in the same manner.
Transport & Storage
Risk of accident caused by damaged bicycle components.
- Always transport your bicycle in an appropriate and careful manner.
- Do not store yourTHM components at an ambient temperature below
-15°C (5°F) or above 55°C (131°F).
Risk of accident.
- Do not allow children to play with your bicycle.

Preparing the Frame
It is imperative you read and observe the safety and assembly information provided
by the manufacturer of your frame.
Secure your bicycle in an appropriate assembly stand.
If necessary remove the crankset and the old
bottom bracket.
If necessary use cleaning solvent or other similar
agents to clean the bottom bracket housing of your
frame.
Make sure that the edges of the bottom bracket
housing are plane, parallel, milled to the correct
dimension and free of burrs
– page 11.
If necessary rework the bottom bracket housing
using an appropriate milling tool (Cyclus, ParkTool®
or other similar tool).
Make sure that the threads of the bottom
bracket housing are clean, free from paint
residues and adequately tapped into the
housing.
If necessary, rework the threads with an appropriate
cutting tool (Cyclus, ParkTool® or other similar tool).
