As Reinier89 showed, a brake should fit just fine. The brake that was used for the mockup does have a slightly offset pivot arm, unlike the Record brake, so I am not sure yet if the Record brakes will fit.
The angle of the seat stay bridge is not very different from the seat tube, so I am guessing (hoping) that I will be able to tighten the bolt with my Park Tool balldriver hex wrench, which can tighten stuff in angles.
