Tightening torques for screw bindings
Use the appropriate tools and torque wrench for any work you
perform on the bicycle by yourself. Every bolt and screw on the
bicycle is important for your safety – be careful when loosening and
tightening them. If you tighten a screw too much, the material will
expand and there is a risk that it will break. If it is not tightened
enough, the performance of your bike may drop as a consequence. In
the worst case, the steering will not work correctly or the wheel will
block! Attention: danger of accident!
To avoid this, screws that are important for safety should be tightened
with a torque wrench. On these tools, the correct torque can be preset.
The unit of torque is the Newton metre (Nm).
The minimum insertion depth of a screw is 1.4 – 0.9 times its
diameter.
E.g. diameter: M5 => 5 x 1.4 = 7 mm
