Creaky seat.

retreads?

I've recently bought a new Fizik Gobi xm saddle & a Fizik Cyrano seatpost for my bike.
Whenever I push down hard on the saddle It makes a really loud creaking noise.
I think it's the saddle rails moving in the seatpost clamp, because when I do the clamp up tighter, it doesn't creak so much - but it still creaks though.
I've put grease on all the screws threads & heads, and even where the seat rails clamp, but it still creaks.........
I don't understand why, because being both the same brand they should fit together well right???
Can somebody help me??
Thanks.

Assuming there isn't a fault in the products, all I can suggest is cleaning everything thoroughly to make sure there is no dirt or swarf stopping you get a good seal. And then repeat the regreasing.

Worth checking that nothing is loose in terms of the rail mounting into the seat platform.

I would be surprised if the rails are creaking in the clamp, the noise is more likely to be coming from where the rails slot into the base of the saddle.

A squirt of WD40 should fix it.

My bike creaks from the seat tube all the time if I dont frequently clean it out and grease it - could be the casue for you too - those pesky creaks are always hard to track down and generally come from somewhere you didnt expect!

I think cycle frame manufacturers are missing a trick, I'm sure there is some sort of military application for a device that can make a sound coming from one place sound like its coming from elsewhere?

but seriously bike frames have bizarre acoustic properties.

i had the same issue with mine but it wouldnt creak all the time, i ended up squirting gt85 into the bracket where the rails meet on the nose of the saddle as i seemed to have located the source (with the saddle off) and haven't had the problem since

make sure you give it a squirt pre-ride and after cleaning

I am 100% sure it's not the saddle/post interface but at the frame/post junction.
I might be wrong though !!!

Wotcha,

Put a line of silicone along the channels of the seatpost mechanism.
Clamp it up as normal and wipe off the excess silicone. When it dries you have a seal that cushions the rails and keeps any bits of grit out of where they can make noises.

I hate creaks and use this method everywhere two metal objects meet, it keeps the grit out and stops creaks

Pulled the whole seatpost head apart again last night and put grease everywhere I could.
When I put it back together.................. IT DIDN'T CREAK ANYMORE!!!!!!!!!!!!!!
I think the problem was where the bottom rail support pivots on the top of the post. Ít's not meant to move but it must just a little bit.
Interesting what happened to my last seatpost......
Bought my bike (scott ransom) second hand, and when I tried to pull it out it wouldn't move.

Guy I bought the bike off said the shop put a bit of carbon grip goo stuff on the post because was having trouble with the alloy post slipping in the carbon frame......
Turned out that the post was well & truly jammed in there. Took it to my LBS & they tried (unsucessfully) to move it for about 1/2 an hour..........

Brought it home again & pulled the seat off & stuck an old set of handlebars in the seatpost clamp so I could get a bit more leverage - after 3 hours solid of squirting WD40 around the bottom of the post & twisting the bars seriously hard I finally got it to move........

When I finally got the thing out I found the carbon grip stuff had stuck so hard to the alloy post that I had taken about 2mm off the diameter of the post getting it out.

Lesson: NEVER put carbon grip censored on alloy!!!!!!!!!!!
