A bicycle that malfunctions can
cause you to lose control and fall.
Inspect the entire bicycle
thoroughly before every ride, and
do not ride it until any problem
has been corrected.
An improperly adjusted or
tightened handlebar, stem, or bar-
ends can cause you to lose
control and fall. Make sure the
stem, handlebar, and bar-ends are
positioned and tightened properly
before riding the bike.
CHAPTER 3: ADJUSTMENT
This chapter lists instructions for adjustment of the parts of a bicycle. After any repair,
inspect the bike as explained in Chapter 1.
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
should be used to make sure you do not over-
tighten the fasteners. Applying more than the
recommended torque to a fastener does not
provide extra holding power, and may actually
lead to damage or failure of a part.
Always perform the simple function tests listed in this chapter to make sure a part is
properly tightened, whether or not the part was tightened with a torque wrench. If a
part fails inspection at the recommended torque, take the bike to your dealer.
Handlebar
To adjust the angle of the handlebar
1. Loosen the handlebar clamp bolt(s) on the
stem (Figures 11-12) just enough that the
handlebar can be rotated in the stem.
2. Position the handlebar to the desired angle,
making sure it is centered in the stem.
3. Tighten the handlebar clamp bolt(s) according
to stem type:
• Welded stems- 100-120 lb•in (11.3-13.6 N•m).
• Forged stems- 150-180 lb•in (17-20.3 N•m)
Stem
There are two types of stems:
• Direct-connect (Figure 11)
• Quill-type (Figure 12)
Adjusting the handlebar height on a direct-connect stem
affects the headset bearing adjustment. This procedure
requires special tools and training so this should only be done
by your dealer.
To align a direct-connect stem
1. Loosen the steerer clamp bolts two to three turns.
2. Align the stem with the front wheel.
3. Tighten the steerer clamp bolts to 100-120 lb•in (11.3-13.6 N•m).
