While the necessity of proper alignment may hold true for the V-4,
the tapered roller bearing headsets (A-9 and current model
Stronglights) allow the bearing races to swivel a bit, so precise
alignment isn't as crucial. (Of course, it is preferable anyhow!)

threads, fork crown face, and the head tube faces. Ordinary bearings allow
some misalignment while the V type and tapered roller bearings must be very
precise. >>
