Carbon seat post

28.5.1 Before your first ride

• Carbon seat posts are only designed for

being used on road and triathlon bikes

as well as on cross country and mara-

thon mountain bikes and their intended

use. Carbon seat posts are not designed

for extreme situations, such as free-riding,

dual slalom, downhill, drops and such

like.

• Only mount carbon seat posts to frames

with suitable seat post clamps. Special

seat post clamps reduce the forces occur-

ring at the clamping slit.

If necessary, use special clamps that are suit-

able for carbon seat posts.

28.5.2 Adjusting the correct saddle height

Release the bolts of the seat tube clamp by two

to three turns. Then pull the seat post upwards

or push it down until the saddle height match-

es your needs. During the adjustment, avoid

any rotating movement of the seat post in the

frame, as this would scratch the surface of

the seat post. Do not use brute force for the

adjustment.

If the seat post cannot be shifted easily and

smoothly up and down in the seat tube, ask

your MERIDA dealer for help.

Never grease the seat tube when

mounting a carbon seat post. The

grease would penetrate the surface of the

carbon material, reducing the coefficient

of friction and hence impairing the stability

of the clamping joint. Once in contact with

grease or oil, a carbon fibre part may never

be able to be clamped in a secure and safe

way again.
