Randonneur porn: Best frame mount pumps and braze-on fittings?

If it were me, I’d get the smaller size HPX pump (360-400mm or 410-450mm) and have your top fixing replaced with a traditional peg and get something fabbed for the disc brake brace.

Yeah it’s ace that. Owner had that added to the rack and colour matched to the original frame enamel of the JT.
