Do Pro Cyclists Change Gear ratio's

Do the Pro's change gearing on their bikes for different stages.
Like for a mountain stage do they change the gearing as to a fast flat stage
?

Yes. For flat stages they use 11-15.5: half-tooth increments :-)

was watching a giro'04 stage and phil liggett exclaimed
"He's got an awfully big cog on th back there. It looks like a 26!"

Tyler Hamilton and the CSC lads use/d compact (50/34) chainsets in th
03 tour in the hilly stage

I thought most riders would as the shifters are easily accessable ther
on the 'bars.....

Paris Roubaix goes the other way with close ratio front rings (53-44 for
example) with 11-21 on the back

A couple of years ago when the Vuelta went up some severe hills (Angliru)
the pros were running triple chainsets 53-39-30 and 12-25 cassettes.
That extreme is fairly unusual though

No. The team mechanics do :-)

Depends on how steep the berg is. Most of them only bother for the
extreme hills such as San Fransisco or Baw Baw or that nasty little
hill near Lara, Mt Wallace.

Let's face it, the 10 speed 11-23 cassette gives a pretty wide range.

Yeah, Angliru is about as severe a climb the Pro´s will do. I think? i
was Millar who got off his bike at the top of it and quit the race as
protest over it being included. Some team cars cant get up there a
times and im pretty sure guys got off and walked up

Let's face it, the 10 speed 11-23 cassette gives a pretty wide range: How
about the 10 speed 12-25 gives an even wider range!
