Main point really, is to have your saddle back far enough that your torso can lean forward comfortably, without having to engage massive 'core' strength, or support yourself with your arms :-)
You have a good range of adjustment with that Canyon seatpost, so experiment a bit.
I'd actually try and move it back first. No more than 5mm. Then give it a try.
When leaning forward on the bike, it's best done by rotating your pelvis forward, rather than stretching arching the back. When you rotate your pelvis, your sitbones tend to move back a little on your saddle.
