Help me fellow racers...... bike noise is killing me....mixinbeatz

I have a click on my giant TCR that is killing me. At first I thought it was the seatpost, I greased the post, cleaned the inside of the frame and greased the bolts but noise continued. I took the seat off, greased the rails and bolts and the noise continued. I greased the headset bolts, stem bolts, to no avail. Greased the water bottle bolts, and the front der. hanger. Greased the back brake bolts as well with no avail. Switched to a different set of wheels and the noise was still present. I made sure that the bottom bracket was tight but I did not fully remove it and grease it. I can still hear the noise when I grab the top tube and push the seat towards the back of the bike. The noise sounds like it is either still coming from the seatpost, or the BB. Is is possible to put enough pressure on the seatpost to stress the BB to the point of clicking by just putting pressure on the seatpost? Any suggestions would help, my bike sounds like a huffy with all the noise it is making!

Does it do it pedaling or coasting; sitting or standing; smooth or bumpy road?

The grabbing it and making it creak thing is sort of weird. Start taking parts off and retry this and see what happens, starting with the saddle. Try putting a different seatpost or saddle on. I can't imagine that pushing it the way you describe could creak the bb.

It does it when I am pedaling and coasting, sitting and standing, believe it or not. I will fiddle with it tonight some more, and see if I can get a better idea of how it reacts out of the saddle and coasting to verify again. Last night I removed the seat, put the handle of a park pedal wrench in the seatpost and while pushing back towards the rear wheel, I clearly heard the noise. Could a bad weld or a crack under the paint make this noise? I think that this is highly unlikely but I am running out of things to take off and re-grease.

Brock -- is this the new frame or the one you crashed (I thought that one was destroyed)? Sounds like a bad weld to me -- something is moving that shouldn't be. Could become a fracture in the future. Look closely at the welds around the seat cluster when you do this. Anything opening up?

It is the new one, the other was broken in two. I will check out the welds tonight to see if everything looks ok.
thanks Dave.

This was on my Morgul aero frame and it started all of a sudden-like last week. I did everything you posted earlier, and additionally removed the BB and re-taped it with teflon tape. The Morgul is worse than any "normal" frame I've ever ridden in this regard because that ultra-stiff aero tubeset is like a big amplifier, making the tiniest creak into an eye-crossing distraction.

finally the lightbulb came on and I recalled that I'd moved my seat around on its rails for the stage race TT, and even tho the bike had just been washed, apparently some remaining grit had worked its way between the rails and the clamp. Removed the saddle, cleaned it up, greased the rails, put everything back the way it was and bingo, no creak.

I already tried switching the seat and greasing the rails. I looked for a bad weld last night and could see nothing. I guess I will ride the noise away, or wait for the frame to break! I don't know what else to do.

Just to note. I had a weld failure last year. Beware. Mine sent me endoing clipped in. I didn't break a collar bone luckily, but the damage was deep and widespread. Led to a fully blown racing season, lawsuit, PT, and over two months off the bike and out of the gym completely.

Best of luck.
