The manufacturing company accepts no

sequential loss. The user bears the
risk in the event of personal injury and
material damage. The manufacturing
company accepts no liability for damage
or accidents caused by improper use of

Quality Assurance and rigidity
testing
•
Every carbon frame ready for de-
livery and every set of (full) carbon
forks are subjected to a rigidity
test. For each frame height and
each set of forks a rigidity toler-
ance range is defined in prelimi-
nary testing. Only frames and forks
which come within this tolerance
range leave the factory.
The rigidity test is used as a Quality
Assurance measure and is performed
on the company’s own test rig. To do
this the frame to be measured is fixed
in place at the rear assembly and the
steering tube. Then the gear crank area
is deflected to one side using a defined
force delivered by a pneumatic cylinder.
As a second step rigidity measurement
of the steering pipe occurs through tar-
geted torsion of the steering head to
the frame. The rigidity values arise from
the ratio of the applied force and the
resulting deflection of the frame area
and are documented on the test sticker
in the operating instructions enclosed.
