This is a head scratcher. Why not have the bikes come stock with a 52-36 and an 11-30 (if using Shimano groupset) on the back? With larger cassettes, more and more companies are going to 52-36 almost universally (believe this is what Specialized and Canyon use on all roadies, or at least their race models). You pick up more range on both ends.

I can see an Emonda or a Domane coming stock with a 50-34 to support climbing, but why in the world would a Madone or a Speed Concept come stock with a compact? A 50-34 is fine if you live in flat areas (unless you're doing a decent amount of sprinting), but if you have to close a gap on a downhill, you're going to spin out way too easily. There's a short downhill (about .3 at 6%) near me, and in taking the KOM on my TT bike, I was pretty close to spinning out in a 53-11.
