Saddle Angle
The seat should be horizontal or parallel with the ground. Slight variation around the horizontal may suit individual comfort
but if excessive angles are felt necessary check other aspects of your position.
Saddle Height
The correct seat height is determined by sitting on the seat with your leg fully extended. Your heel (in flat shoes) should
just touch the pedal when it is positioned at its lowest point. When riding normally with the ball of your foot on the pedal
your knee should be slightly flexed at the bottom of the pedal stroke (see diagram following).
Saddle Forwards/Backwards Position
With the ball of one foot on the pedal and the cranks parallel to the ground the saddle should be adjusted backwards or
forwards to a position whereby the pedal centre is directly below the knee joint.
Very small changes in saddle position can have a substantial effect on performance and comfort. Consequently,
whenever you make a change to your saddle position, make only one directional change at a time and make the
changes in small increments, until you have found the point at which you are most comfortable.

HANDLEBARS AND STEMS
As your cycle may be fitted with a standard 'quill' stem or an A-Head stem, you must check that all the bolts are tight before
cycling.
STANDARD STEM: Loosen expander bolt so that expander wedge is not tight in bottom of handlebar stem. Gently tap the top
of the expander bolt to further loosen the wedge, if necessary. When the expander wedge is loose, move the handlebars up or
down until you find the optimum height at which you can easily reach the brake levers and comfortably grasp the handlebars.
Usually this height is level with, or slightly lower than, the top of the saddle. Be sure the stem is in line with the front wheel.
CAUTION: A minimum insertion ring is marked on the handlebar stem and this marking should remain in the head
tube. Under no circumstances should the minimum height insertion mark be visible on the handlebar stem. It must
be down in the head tube.
When desirable height has been achieved, align the handlebar with the front wheel and securely tighten expander bolt. It is
extremely important to tighten the expander bolt sufficiently, so that when the wheel is held between your legs and the
handlebars are twisted, the handlebars do not move. Do not over tighten, as it may increase risk of injury to the rider. Position
grip portion of handlebars horizontally and securely tighten the binder bolt.
Refer to table of recommended torque values on page 8.
Note: Whenever the handlebar stem is removed from the head tube then the expander bolt should be lightly greased.
Note: On some bike's raising the stem requires brake cable adjustment. Do not attempt this if low profile brakes are fitted
with a stem mounted cable stop.
A-HEAD STEM: Has 2 steerer clamp bolts on the back of the stem, which clamp around the steerer tube. Loosen these bolts
to align the stem with the front wheel. Re-tighten the steerer clamp bolts.
CAUTION: Do not adjust the top compression bolt, this should be pre-set to eliminate bearing play, overtightening will cause
premature wear.
