Correct. Although aero/concealed brake cable configuration required a pair of the elusive "guide cable plates" which were often lost along the way forcing later rebuilds to be non-aero configuration.

Various Italian manufacturers and pro teams also continued to set up similar C-Record and Croce d'Aune levers up non-aero for a year or three post-introduction because that was how it was back then. No need to rush a change from what had been proven over decades prior. That of course led to the same practice for Chorus and Athena.
