Important maintenance information
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 components.
Spirit or petrol should be used carefully - when using such products avoid excessive wiping and
prolonged exposure times.
NOTICE
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.
Risk of accident caused by damaged components.
- Never attempt to disassemble your THM-Fibula racing brakes - 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 (brake levers, cable system, frame, fork, wheels, etc.).
- Always observe the minimum and maximum values specified – see
Technical specifications,
from page 8.
- When conducting assembly steps that require a specific tightening torque, always use an
appropriate torque wrench that is designed for the tightening torque specified.
- Only ever use original THM components which are available from your specialist dealer or directly
from THM.
Improperly performed assembly and maintenance work could also result in a loss of your warranty
rights (liability for defects)!
WARNING
WARNING
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!
If you suspect that your bicycle is defective or is not functioning properly, stop using it and
contact a specialist bicycle workshop immediately!

DISPOSAL
If THM components are defective or no longer in use, you can dispose of them with your non-
recyclable waste or domestic refuse, or ask a local waste disposal company for other disposal
methods (e.g. recycling).
