Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Advice on clamping a carbon bike on a workstand

Is it OK to support a carbon frame by the crossbar (not a compact frame) on a Minoura 5000 stand? The clamp does not go quite small enough for the seat post (also carbon).
I wouldn't do anything strenuous like releasing tight pedals or BB whilst on the stand.

I clamp mine on the top tube all the time ($$Trek 6.5$$). I wiggle the bike till it remains firm in the clamp but NO MORE! I do not do anything that will cause stress on the tube other than supporting the bike. All torqing of bolts etc... are done while bike is on the floor.

Do not clamp a carbon frame or carbon seatpost.
You shouldn't clamp a lightweight metal frame, either.

buy a cheap seatpost to use when working on the bike. or buy a stand that clamps on the BB, never clamp a carbon seatpost, seat tube, top tube.

I've been clamping mine on the carbon seat post for quite some time now, with no problems.

+1 for clamping the carbon seat post. If your clamp is long enough (like 6") with a thick rubber coating, you should have no problem. My clamp covers a large amount of my seatpost, which helps spread the stress.

+2 for the seat post. I make sure it has the minimal force needed to hold the seat post in place.
