Bored and trying to stay dry, I decided to weigh my two Sachs frames.
My perceptions were that the grey frame with the Dura-Ace 9 speed gear and the Spinergy wheels felt lighter than the red frame with Super Record gear. {non titanium pedal axles and bb spindle}
The weigh-in netted virtually identical readings.
Frames can be seen here in the Sachs Twins album:
