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 tightness 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 damage 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
tightened and we list them in this chapter. They should be performed whether a torque
wrench was used or not and will suffice as a test for proper tightness if you do not have
a torque wrench. As an example on pages 22-23 we show a test to 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.
