Parts and Components Made of Carbon
Replaceable Derailleur Hanger
Secure the bolts with medium strength threadlocker (removable with tools)
and observe the torque value of 2–3 Nm. Be sure not to exceed the maximum
torque of 3 Nm.
Bottle Cage
Observe a torque value of 2–3 Nm. Be sure not to exceed the maximum torque
of 3 Nm.
Tighten the bolts carefully by approaching the maximum permissible torque in
small steps. Check the secure seat of the component, as described in the relevant
chapters.
For parts with no torque range given, tighten the bolts gradually and check in
between regularly the reliable fit of the component.
Care Instructions
Components made of carbon reinforced fibre should be cleaned with a soft rag
and clear water. Add, if necessary, a little washing up liquid. Remove tough stains of
oil or grease with a petroleum-based cleaning agent. Never use degreasing agents
containing acetone, trichloroethylene, methyl chloride etc., solvents or non-neutral,
chemical or solvent-containing cleaning agents that could attack the surface! You
can use car wax to protect the surface and make it shine. Polishing agents contain
solid constituents that might attack the surface.
Note:
Carbon components have, like all lightweight bicycle components, a limited
service life. Therefore, have your handlebar and stem carefully checked
by your STEVENS dealer. In case of doubt, it’s always best to replace the
component.
What to Bear in Mind When Braking With Carbon Wheels
As the braking surfaces are made of carbon, there are some things to keep in
mind. Only use brake pads that are suitable for carbon wheels, e.g. from Shimano
or Campagnolo, as they are designed to suit such type of rims. Carbon brake pads
usually wear down faster than conventional brake pads. Keep in mind that the
braking response of the rims needs getting used to, in particular in wet conditions.
Therefore, test your brakes in a place free of traffic until you have full control of
your bicycle.
The brake surfaces of the carbon rims are sensitive to heat. Therefore, when
you are riding in the mountains, avoid any drag braking. Riding downhill e.g. with
a permanently activated rear wheel brake may heat up the material and result in
a deformation. The rim may sustain damage and the inner tube may burst, thus
causing an accident.
Always use both brakes simultaneously and release them intermittently to
allow the material to cool off.
