handlebar stem. Both systems offer their own advantages. However,
threadless systems can be easier to adjust.
In order to adjust a threadless headset, first loosen the two bolts at the
back of the handlebar stem (see pg. 9). Next, turn the bolt on top of
the steerer tube clockwise to tighten the headset or counter clock-
wise to loosen the headset.
Finally re-align the handlebar stem to assure it's straight and re-tighten
the two bolts on the back of the stem.
Always make sure the stem is tightened to the correct torque. It is this
clamping mechanism that is holding your fork and handlebar.
Warning:
THREADLESS HEADSETS - The top nut on
the top of the steerer tube is in place for the sole pur-
pose of making headset adjustments.
Do not ride your bicycle if your headset is either too
loose or too tight. Take it to your Marin dealer for
adjustment.
Headset maintenance requires special tools and
extensive mechanical experience. You should have
your headset serviced by the dealer from whom you
bought your Marin bicycle.
HANDLEBAR AND STEM:
Handlebar and stem inspection and adjustment are described in
Chapter 1.
Before riding you should always inspect your bicycle to ensure that
the stem is inserted far enough into the steering tube. Also, inspect
both stem and handlebar for fatigue. The stem wedge and bolt should
be lubricated every six months.
If you are unsure about adjusting your handlebar or stem, visit your
local bicycle dealer and have your bicycle adjusted by a professional.
SADDLE AND SEATPOST:
Saddle and seatpost inspection and adjustment for height, fore/aft and
angle are described in Chapter 1. Remember: Never ride with the seat-
post raised beyond the maximum height line on the seatpost.
