From 105 and up it is hard to tell the
difference when clean. I think I can tell the
difference between 105 and DA especially
shifting in front and braking. But is it
worth the price difference? I don't know but
Shimano have to realize that they make their
profit because the regular cyclist buys DA
components and I think it's a shame that they
don't offer the proper gearing for the
regular cyclist in DA quality.
"Proper gearing for the regular cyclist", is
that some casette/chainrings configuration that
the pros have different?
From what I read Dura Ace offers, in 10 speed, 11-21/11-23/11-28/12-23
and 12-27, cassettes and chain wheel combinations in a number of
combinations, the lowest of which seems to be 50/34 teeth. They also
offer 7 different length of crank arm ranging from 165 to 180mm.
That should keep most road cyclists happy.

For 20 km climbs with stretches of more the 11% a 34/27 combination is not low enough for a lot of people that can afford a DA group. In the latest DA version they offer a 34/30 gear combination so it is getting better. But why not offer a 34/32 like Ultegra?
You have the money to spend and willing to do so and you are 'forced' to buy Ultegra. What kind of marketing is that?

whatever.
Campagnolo does low gears better now:
