Hi, I currently have a FSA mega exo cyclocross crankset 36/46T. I would like to replace the 46T with a 52T. (so it will become a 36/52).
I also have a 10 speed Shimano 105-Ultegra groupset (12-25 cassette)....
So what problems will I run into?...Chain length?... Front deraileur...?
Any help will be greatly appreciated!

You'll need to add a link or two to your chain for sure.
If you have a FD specifically machined for your compact crank, you might have issues shifting to a 52t ring....I don't really know for sure. Some people get away with using a standard double FD on a compact crankset, which would work fine.
