I just saw an article about Tyler Hamilton using a 110 bcd crank with 52
x 36 chainrings.

I am interested in a similar setup (110 bcd double) as where I live it
is very hilly and I am interested in doing a few 100+ mile rides with
10,000 ft of climbing. I am currently running a Campy Daytona 9sp double
front derailleur and a 9 speed double Daytona rear derailleur. I have a
clamp on front derailleur. Is it possible to run either a 52 or 50 and a
34 inner ring with this set up? I would prefer not to have to go the
triple route due to cost.

50 to 36 is a bit more reasonable. Still a pretty big jump. I'd start with
a 48/36 and see if you can't cover it with that.

My questions are these:

a) With a front double derailleur what is the maximum tooth difference I
can run with chainrings?

~12 - 14 tooth difference range is common on a double.

b) What is the largest rear cogset? I am running a 13 x 26, but have a
13 x 28.

Determined by your rear deraulleur - you could go to a long cage and run a
11x32 if you can find one to your liking.

I am looking at Dimension Cross Crankset.

Dunno what the Dimension runs, but there's a nice Ritchey double that has
those specs - (just received the Riv paper catalog...)
