Comparing FSA crank to Sram Crank!! Need Help!!!?

Question

I Just bought the 2008 specialized tarmac elite and it has the FSA Gossamer MegaExo, 2-piece crankset on it and i want to make the bike completely sram force. Would this be an upgrade or a downgrade on my crank set? Is the sram lighter? And is it stiffer? Those are the 3 things i need to know? 10 points to the one who knows!!!!

I can't find this information anywhere.

Answer 1

I suppose you could do this and it might even be a bit lighter.  Personally, I think I'd wait until your drive train is ready to replace, though.  When the cassette, chain, and chainrings are shot, will probably be a great time to make the upgrade.  Otherwise, I just don't see much bang for the buck in doing this.

Hope this helps.

Answer 2

Need a little more info, BUT, from what you've provided, it would be an upgrade. The Force IS lighter (791g vs 897g w/ bb for both) and it should be stiffer (but I cannot locate published deflection numbers). The Force is carbon, the FSA is aluminum.

The reason I stated that more information is needed is that you don't state crank size. For example, a 165 is going to be stiffer than a 180.
