Who can add v-brake bosses to a finished titanium rear triangle/fork?
any titanium frame maker..
RE: the description, can one spread titanium rear drop outs?
Titanium can be bent, if that is your question..
the bike in question uses Brompton's 2 external cog gear changer, so does not need that. ..
Brompton is working on their own front hub motor, to not make spreading required..
