Have any of the Kestrel Talon owners had seatpost slipping problems? What did you do to solve it?
I have a 2009 Talon SL and have had nothing but trouble with this thing. I have tried everything that has been suggested and nothing has worked.
From the beginning here is the progression. First attempt I put the post in dry and torqued it to 6nm like the manual suggests. Slipped on the first ride so I upped the torque to 10nm. Didn’t really help. Kestrel support suggested carbon assembly paste, helped a little but still slipped. I tried wrapping the post in tape, this was the least successful attempt yet, lol. The internets suggested hair spray, this combined with carbon paste and 10nm of torque worked great for a long time. Then I switched the Talon from tri to a road setup, and had to adjust the seat height. THe hair spray trick didn’t work the first time, so I upped the torque on the bolt. This worked for a while until it slammed down mid ride last month, during this ride I had to stop multiple times and fiddle with it using a small multi tool. Each time i torqued it more until I finally ripped the thread out of the collar.
At this point I need a new seat post clamp. The new Talons have a 2 bolt clamp, unlike my 2009’s one bolt design. Has anyone tried to retrofit a new style clamp? The only LBS that carries Kestrel says that Advanced Sports told them the 2 bolt post will “destroy” my frame and I should not try it. I find this hard to believe.
Can anyone with a 2 bolt style seat post clamp post pictures of the inside of the collar? I would love to see how the carbon frame is cut where it meets the collar.
Only thing that worked for me was a thin brass shim, a la Cervelo Al P3. Got some thin sheet brass from a hobby shop, cut and folded it to fit. Problem solved 100%.
Round posts with the adapter, or the Kestrel aero post all slipped. Nothing worked until I shimmed it. Seems that the opening was not properly sized.

I feel your pain. I noticed that the saddle was pitching forward slightly when the clamp bolt was tightened so I added a few layers of tape to shim the rear of the post and applied paste to the sides & front. Slippage is now minimal.

More info? Did you put the shim on the from of the post, or between the shim and the rear of the post? How thick was the brass? Got a picture?
05 Talon set up for road. Metal aero seatpost. Never had it slip, ever.
So that is 2 votes for the aluminum aero post. Until this thread I had no idea that this even existed.
For $50 I may try it. I wonder if it is slightly larger in circumference than the carbon post. Makes sense based on the fact that bilmas and PhilDBasket both had success shimming the carbon post.
any chance you can measure the circumference of the aluminum post?
I put an aluminum Thompson seatpost on my Talon and it never slipped in 7 years. Even after removal and reassembly, adjustments etc. This was a 2003 Talon.

Mine is an '05 as well, looking at pictures the clamp may be different, the older ones have an internal clamp that tightens across the top tube in front of the seat. Pics of the 09 seem to show a collar on top of the frame at the seat post?

Shim was a simple V shape inserted at the back of the seat tube opening, behind the aero post or behind the round post adapter. Sold the bike so I can’t take a pic. I’ll look tonight for the brass and find the thickness for you.
Here’s a pic of the Cervelo shim. Mine was just like this…
