Mac my friend, I have no clue, but the size of the dump you take in the morning likely has more of an impact on power to weight ratio than the diff in weight of these parts compared to their predecessors :-)

Can't speak to the 2004 C2's - did they change?? I know there was a new streamliner, but didn't know about the C2. At any rate, I run last year's model.

Re: The F99. I have them on both of my bikes. They are pretty light, I suppose - but I am not a big "weight" guy - the difference between the F99 and the Megaforce is less than a GU packet.

I like the Syntace parts I use and have complete Syntace front ends on my road and tri bikes. Combined with Reynolds forks, the front ends of these bikes are far more comfortable than my old bike was.
