That's one of the main reasons I got the stand that uses the fork and bottom bracket... sorry I'm no help!

You can use the top tube but just be careful, it doesnt take a really hard squeeze to secure the bike from moving, especially if all your doing is routine stuff.

Don't even worry about the steel...
The aluminium...just clamp it to the top tube. The bike is capable of with standing all sorts of unbelievable torque forces when you ride it so just doing regular maintenance stuff is no big deal.
I keep an inexpensive aluminium seat post around and pop out the chi-chi post then pop in the manky one and camp to that when I'm doing heavy duty stuff.

The only down side to clamping to the top tube is if you cables get clamped it can kink them or mess up the shifting while you work on it. I work at a shop and the only time we dont clamp the seat post is on tri bikes with areo seat posts then the dropout mount work stand is what we use, but always use the seat post make working on the bike easier and more efficient.
If your going to do something wrong enjoy it.

I was told NOT to clamp the top tube on my aluminum frame. I either clamp the seat post or hang the bike by the nose of the seat like this...

+1 Kylie - I am a fan of stands that use the fork and bb. The tubes are just not intended to be clamped at all ... it takes very little force to crush an aluminum tube. IMHO, stands that clamp the tubes are relics from the days of steel frames.
All that being said ... you can use something like the "Yakima tube top" to provide a clamping area.

My cables are hidden so that's not a biggie; i'll have to check my wife's bike. We have round tubing on each of the bikes, so no aero profiles to accommodate.
Hanging by the nose is good for some stuff, but if I have to turn the cranks to test shifting or do chain cleaning, then it seems like I should have the bike firmly attached.
My worry about the seat post is mostly for my bikes (63 & 61cm frames). It seems like a pretty big cantilever to support on just the seat tube (the whole bike plus whatever pressure I may apply to it while futzing with it)
I didn't consider the BB/fork mount stands (mostly because I didn't see them being used in my LBS). Is it worth taking the stand back and getting another?
otherwise, I guess being gentle is going to be key.
thanks for the responses, everyone!

+100 for Kylie & gshuldes
When I got my Cervelo P2C TRI/TT bike, I got a new stand [Fork/BB mount stand] & a new/another Serfa bike case specifically just this bike...I had/have a clamp type stand I used before on my touring road & Mtb/downhiller bikes but was told by everyone NEVER to clamp this Carbon bike ever!!!
I thought about gshuldes idea with the rack adapter (I use it for my MTB on post car racks) as my former GF had a post trunk style bike rack, but that just made me nervious it riding on a rack/let alone clamped...
I brake the bike down into the case when traveling most times, or it sits in the back of the hatchback/truck/Suburban
As for my choice in bike stands, I use a Park PRS-20 for the lighter bikes (My Cervelo & my All Mtn MTB) I use the older heavy clamp style Park PRS-15 for my Touring Road & DH bikes))
Here is where you can buy it...

Clamp to the seat post....

I finally got a work stand so that I don't have to hang our bikes from a hook screwed into a rafter (or flipping them over onto the seat/brake hoods)
we have one steel frame and two alum frames (carbon seat stays/fork/seat post).
my thought is to just be gentle and clamp to the top tube with a rag in the jaws and rotate the jaws so they sit top/bottom relative to the tube. I've heard people say they only clamp to a seat post (carbon or not) because they're cheaper to replace.
I won't be doing heavy duty repairs anytime soon...more like: cleaning, lubing, adjusting, routine maintenance sort of stuff...hopefully no heavy torquing of anything.
what do you do?
thanks up front!
