The Face doesn't have the Pegasis Face Symbol printed on it anymore, and apparently the new Faces weigh approx. 0.1g more than the old ones. (The pearly blue color of the Face and F:D looks quite nice, IMO.)
Pegasis III only weighs approx. 3.1g, which is quite disappointing since it was advertised that the 'metal powder' in it was supposed to add weight to it.
The Big Bang Metal Wheel weighs approx. 41.9g with all the components together
(The PC Frame weighs approx. 2.5g, the Metal Frame weighs approx. 25.5g and the Core weighs approx. 13.7g), and is as wide as Hell. (No pun intended.)
F:D weighs approx. 5.8g and is of a similar height (when the plastic SF tip is retracted) to 145WD.
Big Bang Pegasis F:D as a whole weighs approx. 51.9g.
