You have a 2007/2008 FSA Gossamer crankset with external BB cups. Most likely a 68mm BSA threaded BB shell. Suggest you remove the crankset and one of the cups to verify. Should not take but 10 or so minutes assuming you have the tools. If you don't have the tools, take it to your LBS and they will properly identify what you have and make some recommendations on replacement. Finally, inquiring minds want to know why you are wanting a new crankset.
