Crankset upgrade

[Hiwaystar]

Looking to upgrade my crankset. Currently have a Shimano FC-R600( 50/34) on a 2010 Trek Madone 4.5. Would really like to install an FSA Energy, but I'm confused about whether this will work. Seems FSA only offers a BB30 setup. Am I stuck with a Shimano 105( or Ultegra) crankset?

Thanks for the help/ advice

Why do you consider the FSA crank to be an upgrade? You've already got an excellent crank on the bike.

There are worse things in life than being "stuck" with an Ultegra crankset. /img/vbsmilies/smilies/biggrin.gif
