Aerodynamic Water Bottles

[Sebastian]

I recently acquired a Cervelo P2K, and am setting it up for TT's There are only bolts for a water bottle cage on the downtube. Is the
Campagnolo Biodynamica "thin" water bottle more aerodynamic in this position than a standard round bottle and cage? does any one have any info on this?

Thanks, the last line is the most telling...aerodynamic bottles on the downtube seemed to help in the case of a frame built for Lance
Armstrong.

In the days of Shimano AX we used to crush a standard cage and use a dishsoap bottle for water. Used to fill in the underside of Turbo saddle with a sheet of stiff foam.
Do it yourself back then.

That did look like a Biodinamica on his bike. Anyone konw for sure?

BTW, the handle-hole in the Biodinamica doesn't seem all that aero to me. I covered it on each side with a piece of duct tape, so the sides are more sheer.
