A Word about Torque Specifications
Torque is a measurement of the tightness
of a threaded fastener such as a screw or
bolt, determined by using a torque wrench.
The torque specifications in this manual are
listed to help you determine the correct tight-
ness of parts and their threaded fasteners.
More than anything, these should be used
to make sure you do not over tighten the
fasteners. Applying more than recommended
torque to a fastener does not provide extra
holding power and may actually lead to dam-
age or failure of a part. For example, over
tightening bar ends can crush a handlebar.
Once a part is tight enough to stay tight and
be safe, it rarely does any good to tighten the
part any further.
We offer a range of torque specifications.
Similar parts in different bikes may require
different torques due to slight differences.
There are simple function tests you should
perform to make sure a part is properly tight-
ened. They should be performed whether a
torque wrench was used or not and will suf-
fice as a test for proper tightness if you do
not have a torque wrench. As an example
after assembling a bike you should determine
if a stem is properly tightened to the fork.
Place the front wheel between your knees
and try to rotate the stem by twisting the
handlebars from side to side. If the stem does
not twist, it is properly tightened. While this
test is somewhat subjective, it places a much
greater force on the system than is required
of the stem clamping force in normal riding.
