Clavicula M³

Maintenance

Important maintenance information

WARNING

If not properly performed, assembly and maintenance work could cause accidents 
resulting in death or serious injury.
-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.

Improperly performed assembly and maintenance work could also result in a loss of your 
warranty rights (liability for defects)!

WARNING

Risk of accident caused by damaged components.
-Never attempt to disassemble your THM-Clavicula component - only THM employees 

are authorised to do this.

-Always read and observe all of the assembly and maintenance instructions in this 

manual, as well as those provided in the manuals of other manufacturers whose 
products are used on your bicycle (e.g. frame, chainwheels, pedals, etc.).

-Always observe the minimum and maximum values specified – see

Specifications

, from 

page 8.

-Only use suitable, undamaged, high-quality tools.
-When conducting assembly steps that require a specific tightening torque, always use 

an appropriate torque wrench that is designed for the tightening torque specified.

NOTICE

Never use a high-pressure cleaner or steam cleaner to clean your bicycle, as the seals of 
your bicycle components are not able to withstand the pressure. If such cleaners are used, 
it would result in corrosion and material damage.
Never use caustic solvents (such as paint thinners, acetone, nitro compounds, etc.) as 
they can attack the surface of your THM components. 
Only use commercially available paint care products and water to clean your THM com-
ponents. Spirit or petrol should be used carefully
- when using such products avoid excessive wiping and prolonged exposure times.
