Operation Manual

Chapter 3: Adjustment 18
To adjust the height of the saddle
1. While someone holds the bicycle, sit on the
saddle without shoes, with the crank arms
parallel to the seat tube.
2. Decrease the tightness of the seatpost binder
bolt or quick-release.
3. Put your heel on the bottom pedal. Extend
the seatpost until your extended leg is
straight (Figure 18).
• When you wear shoes there should be a small
bend in your knee in the correct position; with
the ball of your foot on the pedal.
4. Make sure the minimum-insertion mark on
the seatpost (Figure 19) can not be seen
above the bicycle frame.
5. Lock the seatpost quick-release, or tighten the
seatpost-clamp bolt to 40-60 lb•in (4.5-6.8
Nm) for a 5mm bolt, or 60-80 lb•in (6.8-9
N•m) for a 6mm bolt.
Headset
The headset is the bearing system that allows
the handlebar and fork to turn. Each month
examine the headset.
To examine the headset adjustment
1. Apply the front brake while you rock the
bicycle forward and rearward.
2. Lift the front wheel off the ground. Slowly turn
the fork and handlebar to the right and left.
If the headset bearings move in the frame or
do not turn smoothly, do not ride your bicycle.
Transport your bicycle to your dealer for repair.
The adjustment of the headset makes special
tools and training necessary. Only your dealer
should adjust bearings.
Crankarms
The crankarms connect the pedals to the bottom
bracket. They transmit power from the rider
to the rear wheel, and on some bicycles they
provide braking power.
The length of some crankarms can be adjusted.
To change the crankarm length, remove the
pedals, then install the pedals into the other
position. To remove or install the pedals, see
the Pedals section.
Bottom Bracket
The bottom bracket is the bearing system that
allows the crankarms to turn in the frame.
To examine the bearing adjustment
1. Lift the chain from the chainrings.
2. Turn the crankarms so that one of the
crankarms is parallel to the seat tube.
3. Put one hand on the crankarm and one hand
on the seat tube. Try to move the crankarm
to and from the seat tube.
4. Turn the crankarms.
