I bought the new Canyon Grail last week and rode it 50 miles Sunday on easy gravel and road. So far I’m really happy with the purchase. The bike is very stiff and accelerates quickly, but is also very comfortable with the flexing seat post and ergonomic bars.
At 5’9" or 175cm I’m at the limit for a size small and I’m happy I went with that instead of the medium. The bike is very long and with the short stem it fits me perfectly.
Unfortunately all the accessories are unavailable in the US store until about February. I am using the Garmin bands to mount the Edge unit on top of the bars for now, but it’s not ideal.
If anyone is interested I’ll post a follow up in a month or so after I put some miles on it.
