Hey, thank you for the detailed reply.
The comments are swaying me toward sizing up
I'll tell you how the bike feelsfrom the (short) experience I've had riding it -- I don't want to put in too much wear in case I need to exchange it. Disclaimer: I haven't been on a bike for 6 months, and have only been riding for 1 year, so it's a little hard to know what to look for but I do have a general sense.
The good: I feel like the reach is perfect. I don't feel scrunched up top. The distance between the saddle and bottom bracket feel good, as well. In my pictures it looks like the seat post is long as hell, but I think that is largely due to where the top tube meets the seat tube (strongly angled downward toward seat tube) -- it looks just like the picture Canyon advertises on their website. On the seat post, i'm at the 9.5cm hashmark, whereas the recommended max is 13cm. Also, I can stand over the top tube with a 1-2 inches of space to my crotch.
The bad: I feel like my body is 'low' to the ground when riding -- it kind of feels like my whole body should be higher off the ground than it is. I also feel my torso is a little far forward, and when out of the saddle my body weight seems to be fall ahead of the bars. Lastly, when at a stop light, I can just barely reach the tips of my toes to the ground (not a big deal). Minor toe overlap, but haven't felt it yet during a ride yet.
I'm going to test ride a 56cm Allez at my LBS tomorrow to see how it compares. The specs are similar to that of a size up (medium) to the Canyon Endurace. Which is interesting, because recommendations for Specialized and Trek at my height are both for 56cm, whereas for this model Canyon in between a 54cm and 56cm.
Here are a couple more pics, not in all black.
