Sturmey-Archer offers disc brake versions (6 bolt) for their standard IGHs, but, and it's a big but, Brompton uses an exclusive-to-them super wide range three-speed hub on their 6-speed models AND this new 12-speed model claims to use yet another different exclusive wide range hub.
So, no disc brakes for you.
