They probably come with a decent amount of steerer tube on them with spacers under the stem. You could run a 17 degree stem turned upwards to raise the bars more if needed. And I think there are steerer tube extenders for aluminum steerers you could add on. Just guessing here as I don't own any of those bikes personally...

You might not be able to tell from the pics, but some bikes have longer head tubes than others, and even just an inch can make a big difference. I have friends on race geometry bikes who run their bars pretty high with just the stock equipment. If you can test ride at a local dealer, that could help narrow it down for you...
