Aerodynamic Water Bottles

[T. Field]

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?

Yes, read this...

In the article, John Cobb mentions that in testing, an aero water
bottle worked well on Lance's TT bike's seat tube.

In fact, that's how he raced it - with a large (Campy?) aero water
bottle mounted very low on the seat tube. I guess in the end it's
more of a "virtual fairing" than a water bottle... not that there's
anything wrong with that....

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.
