Happy Holidays!
On my Canyon CF SLX Ultimate the lower headset bearing is an odd size and hard to find. This store, Fushi - https://www.aliexpress.com/store/1100495745 was the only one which had it in stock. Its been a few months only but the bearing is fine. Interestingly bearings on my ICAN Aero wheelset were labeled Fushi too which I replaced a while ago (from same brand) and they have been excellent so far around 2000 miles in.
