Note:
Due to the unmanageable number of components on the market, STEVENS is not in a position to foresee
every product that will be replaced or newly assembled by third parties. Therefore STEVENS denies any
liability for such kind of additions or modifications with regard to compatibility, torque values etc. Whoever
assembles or modifies the STEVENS bicycle shall ensure that the STEVENS bicycle is assembled according
to the state-of-the-art in science and technology.
Note:
Some components have the maximum permissible torque values printed on them. Use a torque wrench
and do not exceed the maximum torque values! If you are in doubt or if you have any questions, contact
your STEVENS dealer.

These values are reference values of the above-mentioned component manufacturers. Observe the values in the
instructions of the component manufacturers.
These values do not apply to the components of other manufacturers.
Danger:
Keep in mind that the torque values given in the chapters
“Recommended Torque Settings”
and
“Recom-
mended Torque Settings for Disc Brakes and Hydraulic Rim Brakes”
override any other torque values.
Caution:
Be sure to use stainless steel bolts only for mounting mudguards and accessory parts.
Maximum Torque Settings of Standard Bolts
Limit values of the torque settings in newton metres (Nm) for setscrews with metric threads and head contact
in accordance with DIN 912, 931, 934. The bolts are greased (friction coefficient = 0.125):

Observe the minimum screw-in depth. In the case of solid (hard) aluminium alloys this depth is at least 1.4 fold
the bolt diameter. In general, the weak point is not the bolt, but the component!
Conversion factors of old torque values into internationally valid SI units:
1 kgfcm = 0.0981 Nm
1 Nm = 10.1931 kgfcm
1 in lbs = 0.112 Nm
1 Nm = 8.928 in lbs
