I have recently changed all the bearings in my suspension of my Nerve XC9. All the bearings were standard sealed radial bearings that I matched from the stamped code.
The main “Radial Pivot” bearing (as advertised on canyon website) was a spherical type bearing – again just matched the code stamped on the bearing.
I did contact Canyon before removing the spherical type bearing, just incase they were a special order and they were quick to reply and offered to supply the bearings, so can’t really fault them.
Not changed headset yet, but ask for cost as see what they say. I would be suprised if you can’t get the LBS to remove it and fit something similar, can’t be that far away from standard
