In fact i was so happy with my carbon seat post that i bought one also for my wife’s Cinelli.
The brand is ADVANCED GROUP, the model is the Carbon monocoque seat post SP 07, it is a taiwanese product and i think is the same manufacturer for Pazzaz and also they have in catalogue a very similar seatpost as the Look Ergopost (too much similar!!!)
I chose this because is a real monocoque without that stupid glued alluminium head that most of the seat post out there have.
Carbon is useful for gain some “comfort” without loosing good rigidity.
Belive me that a Cannondale with some carbon addede will be the best choice.
Now they have the new 2004 frame in allu mixed with carbon but i fear that they were forced to made it due to the “carbon is better” habit of their competitors like Trek.
Carbon is the future but for now i should wait and stay with a good alluminium frame.

p.s. for the steel frame:
new steels like ultrafoco etc etc are light but with maybe more problems than alluminium, plus the rust problem.
Forget the steel, is really out dated. (and sure for steel frames you must buy a Scapin)
If you have money enaugh and you want to be different from our common people buy Titanium, it’s strong but flexible, no rust and will survive to you....
