I bought a Canyon Speedmax CF 8 Disc earlier this year, but due to the weather (US Northeast) I’ve been exclusively riding indoors. Today I decided to go a ride outside for the first time and after struggling with the rear wheel installation (noobie alert!), I noticed some weird noises and I’m not sure if they are expected, since it’s my first time with a disc bike and carbon wheels.

I hear some “clicks”… that doesn’t sound right. Or does it? What do you all think?
Thanks
Only thing I can pick up is maybe your brake is lightly rubbing. It would explain why you didn’t hear it indoors, assuming you were using a wheel-off trainer.
Freewheel / hub noise is normal for this hub (either DT Swiss 360 or 240), no issues there.
Your disc brake is rubbing against the brake pads, it should be corrected. I’m no magician, but it sounds like it’s one side rub only (the disc is too close to either side of the calipers, but the disc is centred). If you’re lucky, it might be corrected by simply turning the through axle a bit in or out.

The thru-axle isn’t designed to have play in it, it should be snug. The solution is to determine if the brake rotor is straight or if it’s a case of the caliper not being centered or maybe a bit of both. Once you nail down the cause, correct the problem.

First, I took the assumption, that the disc is centred, because the disc rub noise is constant throughout the revelation. If you quote me on this, then follow the assumption.
Second, there’s most probably a recommended ideal torque for screwing in a through axle, e.g. 12Nm or 15Nm. However, I guess 95% of us don’t use a torque wrench when installing a wheel. Most of us simply do it by feel and our feel isn’t accurate. I have 2x Aeroad and 1x Speedmax at home, and for each of those 3 I can have a disc rub if I under-screw the axle. Kind of a Canyon thing. If the guy is lucky, this is his easy solution. If he isn’t lucky, none of your end-to-end problem identification manuals would work for him - he’s too novice to handle this problem on his own.

point taken, there is of course the chance that the brake rubs because the TA isn’t snug. I was working off the assumption that it was snug, whether or not it was snug to spec. If it’s loose, then of course tighten it. If it’s snug, loosening it to fix the brake rub would be a wrong approach.
Totally normal! Likely it’s the rear carbon wheel and the air valve knocking on the carbon fiber and propagating through the frame. Wrap some e-tape around it when the air is out of it and put it back in, noise will disappear. I have a cf 8.0 and it did the same thing.
