Titanium, since it's not my money .. cures road salt damage problems,
of at least the Frame
but more pragmatic,
my Studded tire bike has SA Drum Brakes, and I have used a Beater frame,
It did not have disc mounts, still the kind of braking I need on ice,
easily modulated smooth.. , when the street is black ice and walking is sketchy.

this spring , I'm going to tear it down and rattle can some paint on.
