The bike was in a Thule roof rack, where you put the fork into a quick release thing. Impact was on the seatpost, which broke clean of. Roof rack moved about 5 cm and was bend a little. Now I am of course nervous if something else may have happened to the bike. Impact was on the seatpost, but the roof rack was moved due to the connection via the fork. I took the fork of and inspected it wery carefully and also the area around the head tube and seattube. Nothing to see. No play in the headset or anything.
What do you say, were I lucky that only the seatpost broke or is there a big risk that carbon structure in the frame or fork or something else have been damaged?
I know I should have it inspected by Canyon, but it will take weeks to sent it to them and we need the bike, so any advice would be appreciated
i'd reinspect the seat tube, including inside where the post goes. also, the force pushing the post back tries to compress the stays. did the wheel tray bend down where the wheel sits? if so, you can get an idea of the load applied by seeing how much force it takes to bend the tray by hand.
The thing with damage to carbon is that it may not always be detectible upon "visual inspection", plus driving into a garage is a very general statement. We don't know what angle, at what speed it happened, and whether the frame suffered any other damage after the initial hit.
That said, I'd be terrified to ride it without a professional looking at it. And I don't know about you and your wife, but there's no way on earth that I would let my wife on that bike until I knew it was safe.
first time i did it the frame was fine. Front carbon rim, right shifter, handlebars and saddle were broken.
second time ripped the down tube into two, front carbon rim again, front brake calliper, crankset and rear derailleur damaged.
third time ripped the down tube into two, front carbon rim again, front brake calliper and front hub bearings.
The only way to be sure is to get an ultrasound test done on the carbon frame/fork.
it's very rare to have carbon damage without it damaging the paint work in some kind of way.
no damage to garage door
They don't have a scanner, but the regular do these kind of assesment for insurrance companies, when people have crashed, so they have a lot of experience and the verdict was that the frame is fine.
I will however be keeping an eye with the hairlines just to be sure. Thanks for the advice.

Take the bike to the shop and have them inspect it for you starting at all of the drop-outs. Pull the fork apart completely and have them inspect all of the steering parts as well...
