Slightly loose headset?

I think your on the right track with the disc, some are worse than others, I was looking at one the other day thinking it was bound to cause issues with judder as there were drastic diffrences in the pad contact area around the disc, can’t remember the brand though.

I also seem to have this problem. Which is odd, as my 2014 Croix De Fer was a frame/fork build. Headset is nice and tight, i.e spacers won’t spin and any more and it will probably bind, so thinking it’s a brake issue.

Although I imagine I have different brakes to the OP, as running TRP SPyres with the rotors they came with:

Really ruined my first ride in yonks…bah 🙁

I figured I would get some new discs, to see if it helped, but while I was waiting for them to arrive I read this blog. Guy was running same frame/forks/brakes as I was, albeit with different rotor, and started to have the same problem. Solved it, strangely, by applying some copper grease to the back of the pads. Being a master at straw clutching I tried it, and it has more or less solved the issue.

Annoyingly, its’s too late to cancel the rotors I have coming, but sadly I may still end up fitting them as they are RT76s and look quite pimp. 😳

Interesting. Will see how the fit on the Spyres, if they foul they will just take them back to Halfords.
