Noises on the bike: If it cracks when you're sitting down - is it the saddle or the seat post?

Even the best bike shows signs of wear after several kilometres. And some of these are more than just visual. Over time, components start to make noises that they didn't make when you bought them. Unpleasant squeaking, rattling, grinding or creaking noises on the bike are at best just annoying. But usually more.
Noises when cycling occur between moving parts and, depending on the part and cause, can lead to wear - if this is not the cause of the new unpleasant sound when cycling. A check is therefore always recommended if you hear cracking, rattling or whistling noises on your bike. Here we show you how easy it is to track down squeaking and creaking bike parts - for example on the saddle and seat post.

Saddle & seat post as the cause of noise on the bike
The creaking only occurs when you are sitting; as soon as you get out of the saddle, it is gone? A clear case for a check of the saddle frame and post clamp. Grab the saddle by the nose and tail and try to twist and tilt it in relation to the frame. If it is not possible to determine exactly where the noise is coming from, you can treat both possible sources at the saddle and post clamp.
If the saddle creaks...
The saddle frame often creaks in the plastic shell. A little silicone-based spray oil in all the mounting points of the frame can help to calm this down. Allow it to work in briefly before checking again to see if it has calmed down.
Noises on the bike & causes: Seat post
It is best to completely dismantle the post head and thoroughly clean all small parts of the seat post and at least grease the screw heads. But be careful: If in doubt, consult the manufacturer! Some post manufacturers advise against using grease on bolts or clamping surfaces due to the necessary friction or self-locking of the bolts.
Checking the support clamping
Some grease can also be applied under the classic clamps, which are slipped onto the round seat tube, and to the bolt. You should dismantle and clean integrated cone clamps, but only grease the clamping screw. Otherwise the clamp may no longer hold properly. Grease can be applied to the post itself if the frame and post are made of metal, for example aluminium. If carbon is involved, be sure to use special assembly paste and keep the tightening torque low.
