The seat post on my Pinarello Paris is rectangular-shaped with rounded corners. Pinarello's published specs say the post is Aero Full Carbon UD. The rear end of the seat post is also a bit wider that the front end. Because of it's shape, I cannot firmly attach it to my work stand, which worked great for my previous bikes, which all had round seat posts.
I am hesitant to mount the bike to the stand by attaching it to the top tube, which is T600 carbon.

Any suggestions on how to secure my bike to the work stand would be appreciated. Thanks.

Get a stand that holds the bike at the bottom bracket/fork.

It's not that bad...

SMD4, While this is a workable solution, I would prefer not to have to buy another work stand nor to have to remove a wheel each time I want o mount the bike for any type of maint. Thanks, though, for the prompt reply.

After seeing your post, I remember reading about the Hirobel clamp a few years ago. Since the bike(s) I owned previous to my current bike worked well with my work stand and were not CF, I had no need for the Hirobel and forgot all about it. Things have changed, and the Hirobel clamp looks like it ill be my next purchase. Thanks….

I hate BB stands. I made wooden pseudo posts with the silly cross section on the bottom and round on top from old baseball bats.

I hear you. Which is why I don’t use one.

Was just the first thing that came to mind.

I actually mount my carbon bicycle with the stand's clamp holding the saddle somehow. YMMV

I sometimes hook the nose of the saddle onto the stand if its something quick or there's a bunch of crap on the seatpost I can't be bothered to remove. As long as you're not trying to remove pedals or anything else requires a lot of force you should be fine. I find that kind of stuff easier to do on the ground anyways. I'm curious what workstand you have that won't open wide enough for that not-absurdly-wide post

Hooking your saddlet is a poor idea, I have seen enough mechanics go this is fine and knock it off or do something stupid. Just clamp it or work on the ground. Take those extra steps so you don't accidentally damage your frame. The few seconds saved vs the cost of potential damage or the time it takes to fix some damage.

Just thinking out loud, maybe put a piece of foam pipe insulation around the seat post and clamp on that. The extra bulk might make it work better.

The seat post on my Paris is not wide at all. It is just oddly shaped. The read end is a bit wider the the front end and this irregular shape makes it hard for my stand to get a firm grip on the seat post.

I thought about doing what you suggest on the top tube but was leery about tightening the work stand clamp too much, even with that padding. Your suggestion wouldn't work on my seat post because of its odd shape and the inability for the work stand clamp to get a firm grip on the seat post as I described in my reply to trashbiker and shown in the photos in my original posting. The rear end of the seat post is only a bit wider than the front end, but it is different enough so that the stand's clamp can only tighten on the very corners at the rear end of seat post. When tightened on the corners, the bike was very wobbly and unstable and would rock back & forth. I have ordered Silca's Hirobel clamp and it should sold my problem. Thanks....

Wrap a ratchet strap around the clamp then around the head tube and seat tube?

trashbiker

You could probably clamp it tighter than you are. Seat posts are designed to be clamped and usually in a much smaller area than a repair stand head. As long as you don't gorilla fist it you should be fine.

I ordered and received a Silca Hirobel bar. While pricey, I can easily overcome the cost since it solves my problem. Thanks to all who offered suggestions, especially to JohnDThompson who suggested the Hirobel.
