Saddle rocking back and forth

[berkeley]

Oy... the bike is only 3 months old!

Today's ride the saddle creaked the entire time. Everytime I sat back down, creeeaaaakkkk. Totally annoying!

If it's only 3 months old take it back to the shop you got it from and have them fix or replace it. It ought to be covered.

Yep - it should be covered. I have this problem on the back of the tandem and on my Bike Friday. I have a seatpost slipping down problem on my Trek 520. I was starting to think it was just me

If the top of the seat post - where the saddle attaches - is plastic or composite, then you can easily strip the top part, rendering the seat post useless. Change to a seat post that has a metal top part.

Yeah, it's plastic. Oy. I brought it in to the LBS and he says he think he's fixed it. I gave it a shake at the store, and it seems ok, but I'll have to see how it is on the ride into work tomorrow!

Same problem - my seat clamp is metal though. Drives me nuts. At least I finally got it where the range of motion is very small and I can deal with BOTH positions. I would like to be able to adjust my seat and have it stay, but have been too lazy to drag my bike into the city a hundred miles away to have the bike shop look at it. I actually just thought they would think I'm nuts or just too wimpy to tight the bolt or something. Okay, I have no idea why I feel weird taking it the bike in for that. Though they will think I'm nuts for trying the Brooks saddle. They advised against it.
