Aluminum post on carbon frame
My Pinny F4:13 will be coming with a 31.6mm carbon seat post. I'm thinking of swapping it out for a 31.6 Thomson Elite for training and to dial in the seat, and using the stock one for racing. My thinking is also that this will make it easier to work on the bike since I can simply drop in the Thomson post with training saddle attached and clamp it to the stand. But is this still advisable with a carbon frame? Will the lack of flex cause problems in the seat tube? Should I cut it back for this reason? Or not cut it back? Or am I just being overly paranoid about my new baby?
Edit: oh, and if I use an aluminum post, should I grease it? Will this grease make it difficult to use the stock carbon post without a thorough cleaning when swapping?

don't use grease with a carbon frame or post!
Just ride the Thomson. My guess is that it's easier to work with and more reliable than your carbon post. I tossed an elite in my OCLV frame and have had no problems.

another vote for just using the thomson. the carbon post from pinarello is not that light and thomson is easy to adjust and is rock solid.

I have never heard of a race vs. training seatpost. Once you get your saddle hight and tilt set, don't go messing with it swapping posts around.

+ 1. thomson is simply the better choise and why would you have a race and training seatpost? The thomson would be better in a crash as well (which often can happen when racing). It is stronger probably lighter and would hold up better in an accident.

It's not like a training vs. racing wheelset or something. You'll have to worry more about making sure your replacement post is dialed in to the exact millimeter, make sure any saddle adjustments on one post are replicated exactly on the other, etc... I see no benefit to it other than perhaps the obsessive-compulsiveness element of wanting bling gear (and I mean no disrespect by that).
I took out the Pave post out of my Tarmac last year and replaced it with a U.S.E. Alien post. Dropped nearly 1/4 lb (yes, 1/4 lb) and have absolutely no issues with form or comfort with it whatsoever.
Stick with just one post/saddle.

I use Thomson Elite posts in my other bikes and think they're great, but assumed the carbon post would be lighter. If it's not there's no huge reason to use it obviously. I'll go with the consensus on this and get a Thomson Elite for the carbon bike as well.
