Q re: FSA crank on Cannondale Synapse

Ok, so I ride a Cannondale Synapse Carbon Fem 3. It came stock with an FSA SL-K Carbon Light crankset...which I am not very fond of, and am considering swapping it out for a Shimano Ultegra crank. However, my riding buddy pointed out something to me that I had not thought of. He noticed how the FSA crankarms have this weird "bend" to them...something the Shimano cranks do not have. He thinks that Cannondale may have opted to use the FSA crank with the bend in them, because of the thicker chainstays on the Synapse. After looking at the chainstays closely, it does concern me that the Shimano crankarms might not clear them. Is this a valid concern? Has anyone tried swapping out the stock FSA crank for a Shimano crank without any problems?

Thanks!

Linda

I switched over all my 105 components on my synapse 5 to sram force with no problems. I didn't like the fsa gossamer crank so I put it on my beater bike :D

Ultegra cranks fit fine on Synapses. The curve in the FSA crank brings the BB end narrower, not the pedal end wider.
