AmClassic alu seat post + Flite ti = creaking?(12 posts)

AmClassic alu seat post + Flite ti = creaking?mike mcmahon
Aug 19, 2001 8:18 PM
I had this set-up and developed an annoying creak when in the saddle, especially when climbing. I greased the post, greased the rails, and just about everything else in the vicinity of the post and saddle. This would help for a short time, but the noise returned. This morning, I swapped out the AC post for a Thomson I had on my other bike and am hoping that will be the end of it. Has anyone had similar problems with the AC/Flite combo?

I do remember a few years back there was an issue with Flites and AM posts, but it was an issue with the saddle shell bottoming out against the top of the clamp. I think a new lower-profile clamp desigh fixed that one. But my memory may be bad.

Sounds like you've tried the logical stuff with greasing everything. Only thing I could think of is that there could be something (dirt, etc) in the clamp parts causing the creaking.

I have the Thomson/Flite combo and have never heard a sound. If you still get a creak with this the seat rail/shell junctions would be my best guess at where the noise is coming from. Either that or there could be a problem with a bent rail which cannot be clamped properly.

These are my best guesses. Hope they help and good luck.

I've got the new style AC "two piece" Al post on my 281 with a Flight TA (ti rails). Not a squeek out of this combo! :) I like the post. seems pretty solid, good adjustability, and relatively cheap.

I've got no idea why yours gave you a problem. Although I like my AC post, the UPS man will be delivering my U.S.E. carbon post today so the AC is getting pulled shortly.

good rides .... sorry no help on the post issue

I am experiencing the exact same problem with my AC post and an ERA seat with titanium rails. Ive done exactly what you did with the grease with no luck. Then I took the seat off and pulled the lower plate off the post (the one that the level adj bolt bottoms up to) and tried inserting a thin washer on top of that bolt to see if that is where the creaking was comeing from but it failed, still creaks. Im really not sure what to try next other than ear plugs. ugh. Hope we figure something out.

Just wondering if anyone with this problem has called AC. There are a ton of these seatposts out there, so I doubt that the problem is isolated if 2 folks here are experiencing it with different saddles. Especially since the common causes have been addressed. Do you both know for sure that the creak is caused by the rails? I cannot remember the exact design, but the head is not bonded to the post (like Dura-Ace and others)? Not attacking your diagnosing abilities, just offereing other suggestions (thinking out "loud") of where the maddening noise is coming from.

An option could be to call/e-mail AC customer service or tech support and see if this is a known issue. Maybe they have an easy fix other than foam q-tips stuffed into your ears.

I have the exact same set up. The creak was killing me. It turned out to be the seat rails where they insert into the nose of the saddle - nothing to do with the post at all. I shot some 2part epoxy in there and no more creaking.

Again, this may not be what's going on with yours but it fixed mine.

Cheers
Thanks allmike mcmahon

Well, everyone except MJJ. ;-) Anyhow, I've put the AC post on my back-up bike, which also has a Flite ti saddle. If the creak continues on that bike, I'll try the epoxy fix. I've got to say that I like the easy adjustability of the Thomson post, and it looks better on my back because it's black.
Customer Service, Ill try that.Like2bike

Ok, seems as if they dont get many complaints of this problem but here is what he recommended. He said get some of that plumbers tape(that white tape that you wrap on threads for plumbing leaks) and wrap it on the level adj bolt and on the threads of the main sinch bolt as well as putting some on the dome part of the bolt down by the head of the bolt and try that. He said that they use that for bottom bracket creaks quite often and it seems to cure that problem. No free gear:( but if this doesnt solve our problems, he will send us new bolts and plates if needed. Im going to go put some of that tape on my bolts now and Ill ride tonight. Fingers crossed.

Well, I used the plumbing tape on the bolts of my seat post and rode it for about 25 last night without a sound. Now just to see how long it will last, hopefully it wont be a short fix like the grease was. Give it a try and be generous with the tape.

Hope that helps
