I am currently riding a 2013 Giant TCR Advanced SL4, which came spec'd with an Ultegra 6700 53x39 crankset with BB86. I am looking to change the crankset, primarily to go to a 110bcd and most likely a 52x36 setup. I wouldn't rule out 50x34 though. Since I am changing out the crankset, I would naturally like to go lighter while maintaining a similar stiffness to what I currently have. Intended use is all around with an emphasis on criteriums, flat road races, and training. So far I keep coming back to Rotor, but I may be missing other alternatives.

What is your weight and price range? This will greatly influence relative stiffness and "bang for the buck" - teh Giant is BB30 or 86?

Currently has a BB86 bottom bracket, but I believe it can accept BB30 and other configurations.

My weight is 157 pounds/or about 71 kilos.

Budget ideally is $400, but that isn't fixed in stone.

Red Exogram. +1. Then just swap the chainrings for Stronglight CT2's or Praxis and save another 50 grams.

Red Exogram. $£/g on it is phenomenal ... obviously depending on what you have already, but from Ultegra you will lose 200g or more

I would also say the Red Exogram. You can get a great price on eBay and then purchase some different/lighter chainrings.

I bought a compact 50/34 and some Extralite chainrings and fnd them stiff enough but I don't race just some quick group rides or solo training.

I appreciate the quick feedback and seems that SRAM Red is the clear winner.

I'll see if my OCD will let me have a SRAM logo on a Shimano bike. :)

I'll second the rotor 3D crank, very versatile if your changing rings and will look better than anything from shimano would with aftermarket rings on it.

You can always sand the exogram crank and save a couple of more grams!
