Hollow Leg’s Bikes (Mason Resolution, Dolan Tarck Bikes, Brompton, Local Framebuilder Specials; Fixed & Gravel)

Annoyingly there’s a small amount of rear disc rub. I tried to reposition the caliper but it always seems to work its way back to the same place. Perhaps the frame needs more facing on the caliper mount so I’ll book it in with the shop that build it so the can take a look.

Parallel Handbuilt often raves about using copper washers for flat mount, supposedly stops the caliper from moving around.
