Intended Use
The various models of SQlab stems are developed depending on the model for the different areas of application MTB Tour & Travel,
Trekking and City Comfort and have been tested accordingly in numerous tests. An overload and damage to the stem is influenced by
the nature of the traveled surface, the driving skill, the driving style, the rider's weight or the total system weight and other special
events, such as driving errors, falls and accidents. When describing the intended use, we follow the international categorizations ASTM
F2043- 13/ DIN EN 17406, which describe the different areas of use as precisely as possible.

Exceeding the individual load limit of the components
Risk of falling due to breakage of the components
•
Adhere to the permissible system and rider weight.
•
Use your saddle only in the intended use category or in a lower use category (according to ASTM F2043-13/DIN EN 17406).
•
Make an extraordinary inspection after situations with particularly or unexpectedly large force impact, such as after a fall,
riding error or an accident.
•
In case of doubt, the possibly damaged component should be replaced prophylactically. In such a case, better play it safe
and ask your SQlab dealer for advice.
