The seatpost only has one job. And yet it is often a tricky endeavour until it reliably and permanently holds the saddle where the cyclist wants it.

TOUR gives tips.

Degree of difficulty: for everyone

You will need:

  • Tool: Hexagon socket, torque spanner, spirit level
  • Excipients: Fat

Tips & Tricks

1. frame supports that are shorter than 40 millimetres put an above-average load on lightweight saddle frames made of titanium, titanium tubing or carbon - there is a risk of breakage! Sharp edges can also damage the material.

2. if the front or rear bends of the saddle frame are clamped, there is a risk of the saddle frame or seat post breaking.

3. use the torque spanner to check that the seat post fastening bolts are secure after 100 to 300 kilometres and then every 2,000 kilometres.

4. check whether your saddle still swings. Some frame clamps are so high that the saddle cover almost rests on them. A gap of two centimetres ensures suspension travel and therefore comfort.

Patent seat posts

1. the saddle angle is adjusted using wedge-shaped supports or serrations between the head and the support. The finer the toothing, the better. A central screw clamps the connection.

Two-bolt patent seat posts

1st advantage of this technique is that the two screws are less susceptible to breakage. Dismantle both screws until you can remove the upper half shell. First place the saddle frame on the lower half shell and then place the upper half shell back on top.

Seatposts with yoke clamping

1. a movable half-shell rests on the actual support, which holds the saddle frame. The upper half-shell is pulled down using two bolts, one behind the other when viewed in the direction of travel. If the front screw is tightened, the saddle nose lowers, if the rear screw is tightened, the rear lowers. To mount the saddle, loosen both bolts just enough so that they still engage in the thread. However, you should first remove ungreased screws completely and grease the thread and head support. Slide the lower half shell out sideways to place the saddle frame under the upper half shell.

Seatposts with partially concealed yoke clamping

1. here the front bolt lies exactly in the centre axis of the post. Advantage: The support is offset, the saddle can be pushed further back. Disadvantage: The front bolt is difficult to reach. Undo both screws until you can pull out the lower half shell.
