Bicycle Mechanics - Seat Post clicking on 1997 Canondale

I have a 1997 Canondale T2000- all aluminium touring bike. I like it a lot and it makes a great back-up bike. It had a clicking sound every 1/2 pedal rev, which after some tepidation I traced to the seat post. It was not loose, but I regreased it and retorqued it. It was fine for a day. Now the click is back. Asked my bud, who is head mechanics at the LBS and he said this vintage Canondale was notorious for this problem. Something about the design of the seat tube. Do anyone have info on this? More importantly, does anyone have a good suggestion on a more permanent fix?

If you have thoroughly greased the seat post, I'd suggest looking for the creak in the seat cradle. Grease the bejeebers out of that too. Also grease under the seat collar. Grease everything in sight, in other words.

I'm not sure how the "design" of the seat tube has anything to do with it: a tube is a tube as far as I know.

Point taken. More grease. As to the tube, the LBS mentioned that it may not be a staight tube. I could not see too far down, so really could not tell.

I have had seat post problems on my 1999 Cannondale R 600 before. Even though the sound seems to be from the seat post it could be traveling from somewhere else. Try removing the pedals and an cleaning the crank arm and pedal where they touch. That worked for me once. I also once has a click/creak that was due to the quill stem and not the seat post or saddle. Since the sound is predictable it may be from the chain ring bolts.

Also try pulling crank arms greasing and putting them back on. It might be alittle loose and need to be retorqued. Sound travels bad in those frames.

Yeah, pretty much clean and grease every metal on metal interface in the neighborhood before you go looking further afield for the cause.

Have you tried a different saddle? It could be the rails.

Well, some background- new cranks, new BBB, new pedals, new chain, new quill and headstem. None of that changed anything. I thought about a new saddle. Pulled the seat post and regreased it. Took a test ride and voila it was gone, but not for good. It returned during a recent century, but now it is muted somewhat. Just really want to fix it permanently.

I had a click that turned out to be the saddle rails where they enter a plastic block at the front of the saddle. A squirt of silicon spray fixed it.
