The German "Tour" (issue 2011/3: "Vorsprung mit System", p. 112-122) magazine tested 4 hand built wheels againts 12 factory built ones.
The following is for the year 2011 (all the wheels are from 2011), (mm) = millimetres, (N) = Newton, lateral stiffness (front/rear).
In terms of aerodynamics only the
Mavic Kysrium SR and one of the hand built wheels (28/32 spokes) do not cut the mustard. The wheels were tested with
Continental GP 4000 S tyres. Aerodynamics is being tested by means of a wind tunnel where the angle of the oncoming wind in relation to the FRONT wheel is being altered from 0 to 25 degrees in steps of 2.5 degrees. The unit of this measurement exercise is Watts.
The wind tunnel (CMEFE) is located within the technical university of Bern in Switzerland.

Riesumo un vecchio test fatto dalla rivista Tour,ho trovato i dati relativi alle R3,Zonda e Shamal(possono essere equiparate alle F0),i dati sono interessanti:R3 e Zonda risultano essere superiori come rigidità ed aerodinamica,pagano qualcosa in termini di inerzia rispetto alle Shamal essendo un po' più leggere
