nope.
i believe centaur doesnt use bearings in the shifters and is considerable heavier. plus, no where near the sex appeal.
Don't know about the weight, but having spent a few hours poring over Campag parts books to get the background for rebuilding my 1999 Record Ergos, I can say the following about the differences between various types of Campag Ergos (up to and including 2006):
1: Mirage, Veloce and Centaur are ABSOLUTELY IDENTICAL under the skin (same part numbers and everything), the ONLY difference being the material of the brake and shift levers. Centaur shift levers are the same as Chorus alloy, by the way.
2: Record and Chorus are absolutely identical (again, same part numbers), except the brake lever blade (the shift blade is the same as Mirage, only with a tacky fake carbon sticker on it, so presumably actually heavier than Mirage!). Given that both Chorus and Record levers are carbon, I can't believe there's a great deal of weight difference...
3: Between Mirage/Veloce/Centaur and Chorus/Record, the ONLY difference in the internal mechanism is the presence of two small ball bearing races in Chorus/Record, where the lower levels get a simple bushing system instead (this is why Mirage/Veloce/Centaur are said to need 'running-in' for some distance before the shift frees up, where Chorus/Record are good to go straight out of the box). The bush also means one small pivot (where the shift lever pivots) has to be very slightly different, but it has no effect on operation.
Apart from that, just about everything inside a Mirage shifter is exactly the same as Record. Doesn't just look the same - same part number, everything, completely interchangeable.
4: The only exception to all this standardization is Xenon, which is totally different internally, and just about nothing is interchangeable with other units.
5: The only other difference between groups is between 9 and 10 speed. This is simply a matter of changing the index wheels (one for downshifting, one for upshifting). You can convert most 10spd to 9spd or 8spd and vice versa, as well as adapting to different Campag standards (pre-2001 9spd was different to post-2001). For example, to convert any 9spd front changer to 10spd, you need index wheels EC-RE061 (downshift) and EC-RE062 (upshift). To go the other way (10spd levers to 9spd shift), you need EC-RE063 and EC-RE133.
