Andy looks terrible climbing: his arms are almost locked out they're so straight. He has to get out of the saddle and shift his weight forward to bend his elbows.
And I'll even say Nibali looks bad. Shoulders are strained and forward. He's obviously able to descend anyway, however.
Merckx may be on different equipment, but I was evaluating how his shoulders look. I don't care about the reason.
Here's Cancellara: relaxed shoulders. Compare and contrast with Nibali following:
But seriously I don't think you will get a relaxed position from Andy in a race.
Nibali looks fine to me descending or climbing.
Maybe you are not putting enough shoulder into it. Think about it when you do your next climb.

The type of descent dictates the position.

i think most people have bars too high to account for neck ache, but the tension generated in the upper back and scapula area increases the higher the bars go. the torso will know where it needs to be from hip flexion but is struggling to get there a lot of times because it's being held up by bars that are too high.
so after a while aches and pain sets in so people think they need higher brs again because they're aging, it's probably just an over use injury that can be rectified by massage, stretch and bring the bars down far enough to allow for natural curvature to take place in the spine which allows muscles to relax.
so maybe some people need to ride smaller frames and slam their stems provided that saddle position is correct and use massage and stretch to cure the old aches.
just my thoughts and opinions.
Muscles relax when they are out of the extreme ranges/limits of their movement. Bike geometry has hardly changed at all over the years, and bike fit was pretty well sorted back the late 70s (about all that has changed is shifter/brake position). There is no reason one should have to resort to massage and yoga to ride a road bike, barring some serious physical limitation. The primary culprit for fit and positional problems today is saddle height. It's very often set too high. This results in pain in the back, neck, etc., and it forces many riders to have more handlebar drop than they can handle (and more than the frame was designed for). As an example: according to CONI a 56 cm (c-c) frame was designed for a saddle height averaging about 72-73 cm. This would produce an "old school," fist-full-of-seatpost fit. Since hoods went up with the invention of integrated shifters, all that is needed is to drop the frame size down by a cm or two, and viola, you have a perfect fit with adequate handlebar drop, assuming your proportions are not freakish. Tweak the saddle height as needed. Kiss pain goodbye. Some pros still adhere to this type of fit; Eric Zabel's bikes always looked very close to this standard.
Excessive reach also tends to thrust the shoulders forward a lot more. The way I think of it is track sprinters vs. Pozzato. His bars are so far away that he has to rotate them to some weird angle just so his wrists aren't in pain when he's gripping them. If you watch him race he also has a huge transition from seated to out of the saddle riding to get over the pedals. if you look at lots of track sprinters, or even someone like Cav, they use quite a bit less reach for their height and with their hands positioned more below their shoulders have more leverage during a sprint.
For years I had people telling me I ran too much drop so I raised my bars. I felt cramped and uncomfortable so these same fitters said to just increase my reach. Handling suffered and I had more upper back pain than ever. Even at 6 feet 2 I only use a 120mm stem, but my drop from saddle to the bars next to the stem is 12.5CM and I run classic bars so my drop to the grips is around 14cm and a lot more comfortable, better handling, and more stable. My shoulders and upper back are more relaxed and I can actually use leverage on my bars during a sprint.
What is CONI?
Now i have arounf 13cm drop and a pmp seatpost which has 14-15mm of setback with saddle pushed back from centre say 5mm. Frame has a 54.5cm top tube and stem measures 125mm. All this goes against most recent fitter saying i'm too big for such a set up. I am comfortable.
As Hogg has also said, lots of pros might appear to have bad fits, but sometimes thats as functional as they can get with the riding and racing they're doing. Not everyone is going to look perfect on a bike.
At a certain point all fitters have dogma they cling to otherwise they wouldn't know how to fit a bike. There's relatively few things about fit that have any sort of scientific proof. I think Hogg's balance test is a smart idea, but know from working with one of his certified fitters that most people have no idea how to use it or what point in the fit process and can actually pass it in many positions that they shouldn't be riding in. If only Hogg and a handful of people around the world know how to correctly use it I'd consider that a lot less helpful than some basic ballpark guidelines found in a fit book.
When I got my first road bike I used some formulas to set it up. After 4 fits with 4 different fitters with every training known to man under their belt low and behold my seat height is the same, setback is 5mm off, cleat position is identical, and the only thing that has significantly changed is where they put my bars. By far my worst fit of all time was by someone that uses a lot of Hogg's ideas in terms of appearance, comfort, and performance. So one could argue I spent a lot of time and money basically moving my bars around and trying out different seats that didn't work since I'm still on the same one.
