I have the same bike, few changes but still set as a SS, rear QR is being a big pain in the ass, it creaks and moves when under power, I even managed to get the wheel off the dropout in a steep climb...
Currently deliberating on getting new wheels done, got some American Classic hubs for very cheap
There was a recall on the rear mech hanger - I think because it caused the rear QR to slip. Give Evans a call, they'll probably still replace it FOC...
That or use a closed cam skewer, I swapped to an XT skewer when I first got it, before the recall, and that fixed things.
That makes a lot of sense, I'll try to get that hanger replaced.
About the tyres, I was thinking to get gravelkings, in 40c threaded flavour, and set them tubeless, but can't complain about the nanos, durable and still no flats.
