Not warranty as such but when I flew to Australia with my road bike, the thin top cap bolt got slightly bent in transit – not enough to stop me tightening the headset but enough to be annoying.
At the World RR Champs in Wollongong, I spotted a Canyon stand so popped over and had a chat with them, they immediately phoned through to their Melbourne HQ and one of the guys who was travelling to Wollongong later that day brought a spare headset top cap and bolt with him. I picked it up the following morning and tried to pay for it but they wouldn’t accept any money.
So yeah, top service, they didn’t need to do any of that – could easily have said “well it’s just about working OK, sort it when you get back to the UK” but no, super helpful. 👍
