SADDLE AND SEAT POST
Inspection
The seat fixing bolt and the seat post binder bolt should be checked
for tightness and adjustment every month. On removing the seat post
from the frame, you will notice a mark about 65mm up from the
bottom with the words “max. height” or “minimum insertion”.
To avoid damage to either the seat post, the frame
or possibly the rider, a minimum of 65mm of the seat
post must always remain in the frame.
Lubrication
Remove the seat post from the frame and wipe off any grease, rust or
dirt. Then apply a thin film of new grease to the part that will be inserted
into the frame. Re-insert, adjust and tighten the seat post in the frame.
