Road Cycling It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle. -- Ernest Hemingway

I'm seriously considering an 07 Expert. How do you like it? What did you pay?

To answer your question, I'd have the Specialized dealer check it out.

What seat do you have on the bicycle? And is the post carbon or aluminium? My best guess is that the 'cracking' noise my be more of a creaking noise. This can either be the rails of your seat and their connection to your seat... OR, if the seat post is alum, mark it's height, take it out, grease the portion of the shaft (grease it very very well) that is normally inside the tubes, and reinsert, and tighten it up...
I'm not sure, personally, about greasing carbon parts - because I've yet to need to... perhaps someone else can talk about that...

The seat post is specialized carbon FACT with zertz insert and the saddle is the Toupe team carbon reinforced.

Might not be the seatpost. Does it happen when you stand too?

FWIW, I ride a Tarmac Pro and don't have this noise. I second the comment to take it to a Specialized rep.

I found this:

"That little creaking sound. I love my Specialized Tarmac, but it has been creaking all year. I've begged and pleaded in the shop and they always tell me something like... "I dunno, creaks are really hard to find. Probably in your pedals". But I've changed my pedals and it still creaks. I thought I had finally nailed it to the carbon fiber Specialized seat post. You know the one with the zertz insert. I shelled out today for an Easton. I was all fired up to get it on the rig and take it for a spin to hear that beautiful sound of... silence. Still creaking. @#% Well, maybe it's the saddle after all. Switch out the Selle San Marco for the Specialized Toupe. Still creaking. Double @#%."

My wife's Roubaix Expert makes the same type of sound...We've swapped out the stock seat post and it still does it, but at a less intensity....I think it has something to do with the seat post clamp...Does the Tarmac use the same one?? BTW in our case we have greased the crap out the rails and the seat clamp mechanism.

[edit]
Should have checked the Specialized site first...From the photo I can clearly tell the seat clamp is totally different...

I'm going to guess that the OP has this type of post...

As do I. I was also getting a creaking and popping noise. It would creak when pedaling and going over rough pavement while I was seated. Un-weighted, the creaking would stop. The popping would occur when I weighted and un-weighted the saddle. I swapped the post for the carbon one that came on my old Allez (no zertz) and it seems to have solved the problem for now. The shop swapped my old post that came with the Tarmac for a new one but I have yet to try it out.

Similar problem on my S-Works Roubaix. I found that it was coming from the seat rails. I took the seat off, cleaned the rails, re-installed, and the creak is gone. I've had similar creaks with handle bars, and found that cleaning the clamps and clamp area on the bars eliminates the creaks. Hope yours is as simple to fix.

Perhaps that is why the 08's don't have that style seatpost in any model anymore?

That is their lower end seatpost, and I had one..it did creak...also unless you have a saddle with a cut-out, it's pretty impossible to adjust. I upgraded to the S-works carbon post, and aside from the seat sliding in the rails, it's quiet. I DID however ride a Toupe saddle for a while, and it did creak also as the seat flexes a bit..

Hope you find YOUR creak!

I think I have the same seat post (carbon fibre, zertz insert) on my Allez and I haven't had any creaking problems.

I just got mine last week ($1,899 new, closeout at a LBS, triple). I rode 80 miles over the weekend and I loved it. It's not exactly as light as other bikes here (18 pounds without pedals), but coming from a 22 pounds Aluminum bike (Specialized Allez), it feels like a great upgrade.
No cracking noise at all.









NOTE: I removed the dork disk after taking the pictures

I was going to say....isn't there a special rule about Dura ace and a dork disk on a bike...BTW, that was one mother of a dork disk...How bad do they expect a person to over shift a chain??

Oh yea, drop the bag and flip the stem...Sorry had to say it...

Bike looks good! Have a fun time riding her...

That's not a dork disc, it's a Frisbie.

To attempt to get rid of the creak, ask your shop to purchase (if they don't have any) some Tacx carbon grease (or something similar, but I don't think it is technically grease). This is especially important if you are running carbon posts in aluminum frames.

Ask them to use some on your sit post and seat rails. If that doesn't fix the problem, after checking the tightness of your seat post and the clamp on the rails, you may ask to borrow another seat post to see if that fixes the problem.

My LBS has had some issues with the Specialized Zertz posts. They have seized on us numerous times and do tend to make noise. However, it seems that it has been fixable.

You should be able to get rid of it with a little work.

Not sure if it has been solved yet. I ride a 04 sworks e5.
Loosen the seat clamp and push it down onto the frame. the seatclamp likes to slide up a bit and start creaking. at least in my exeperience.
