14. The suspension seat post

Suspension seat post

Suspension seat posts enhance the cyclist’s

comfort when riding on uneven ground. They

can be used on roads and field tracks as

well as for cross-country cycling. However,

suspension seat posts are not suitable for dirt

biking, dual slalom and downhill riding etc.

14.1 Adjustment

To increase the initial spring tension you first

have to remove the seat post from the frame.

Before you do this, mark the position of the

seat post in the seat tube with a pen or adhe-

sive tape or the like.

Release the bolt or quick-release that clamps

the seat post to the frame and pull the suspen-

sion seat post out of the frame.

The adjusting bolt is located inside the seat

post. To increase the initial tension, turn the

bolt clockwise with an Allen key. To relax the

spring, turn the bolt counterclockwise. When

turning the bolt counterclockwise (as when

looking at the bolt from below) do not release

it beyond the point where it is even with the

seat post, as the mechanism could otherwise

fail.

If the setting range does not meet you needs,

you will need to replace the springs inside the

seat post with harder or softer ones. Only use

springs from the original manufacturer.

As a rule, suspension seat posts are adjusted

for a cyclist of average weight, i.e. 75 kilo-

grams. Their shock-absorbing properties can

be altered either by adjusting the initial spring

tension or by exchanging the springs.

Grease the post over the length to be inserted

into the seat tube (except if you have a car-

bon frame; for more information see chap-

ter 28. “Special characteristics of carbon”).

Clamp the seat post tight and check that it is

firmly fixed inside the seat tube (see chap-

ter 8.1 “Adjusting the saddle to the correct

height“).
