A link would be nice.

 

I remember a few years back thinking I needed another gear as I was maxed out, with a tail wind and really wanted a little more speed.

I'm of two minds on this, I think it might be better to better to have a double instead of a triple with a 10 speed cassette. You can get fairly large ranges in cassettes so you could get a fairly wide range.  E.g. with a 40/28 with a 11/32 cassette you can go from 5.8 mph on the low end at 80rpm using 28-32 to spinning out 36.2 mph at 120 rpm using a 40-11 combo. 

 

If you're using this for touring, isn't the SRAM apex road group which has a 11/32 cassette that you can use with a 34/50 compact double sufficient?  You get the 34-32 combination for a really low end and a 50-11 that'll let you go 40+ before you spin out.

You can get the same range in 9-spd as in a 10-spd you'll just lose a few intermediate gears which shouldn't be an issue for loaded touring. But the market seems to be phasing out 9-spd.

I'm not sure what Jtek has to do with this, but if you are running 10 speed Campagnolo you have for years been able to run a triple (Comp model) crank with standard Ergo levers. 

 

Standard Campagnolo cassettes run as low as 13-29T but IRD makes wide range 12-32T cassettes that take a long cage rear mech.

 

And of course there are the compact double options as well.

Phasing out 9 speeds. Pffft. You can tear my 7-speed from my cold dead fingers. Bigger chain is less wear.

No need for Jtek: Campy 10sp shifters shift Sram 10sp derailleurs with sram/shimano 10sp cassettes. Campy also allow for trimming on the front derailleur, unlike the indexing of shimano and sram.

 

Campy 10sp shifters also work great with shimano 8sp derailleurs and cassettes; the range is still the same as envane x pointed out. I use this setup on a couple of my bikes and it shifts way better than my shimano 105 group ever did. I like the eight speed stuff, it's super cheap and way more durable.

 

S: what is this 40/28 double you speak of?

With a mtb crankset, you can swap out the chainrings and get a 40/28 double.  I'm not sure if you can get the same range on a road bike due to the small size of the 28 chainring. Might be possible.
