SAFETY 

Intended use 

 
 
 

Fundamental safety precaution 

 

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! 
 

Assembly & Maintenance 

 

 

The THM stem is approved for a total weight (bike+rider+luggage) up to 110 kg (242 lbs.) and can 

be used on road bikes. The stem must only be used with steer tubes of 28.6±0,1 mm (1 1/8 inch) 

diameter. 

 

 

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 the specified tightening torques for the screw connections.  

 

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 THM components before each journey to ensure the surfaces are 

completely undamaged. Send us your THM components for inspection before further 

use if damage is visible (cracks, fractures, deformations, deep scratches in the 

paintwork which extend into the carbon structure, large abrasions, etc.) or if you are in 

any doubt about their functionality. 

 

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 improve your 

personal safety.
