As Maelochs sort of hints at, make sure you know which bottom bracket to get with the crank. A quick search on your bike suggests its a pressfit but I didn't see what standard. The upgraded shimano crank will probably be a direct swap and I'm sure the other crank has a bb that will adapt the crank to your bike but, know exactly which BB you will need to fit the crank you're looking at if changing to something different. Personally I'm cheap and don't need incredible accuracy so I'm looking at the new sram force crankset with integrated powermeter, but I'm also not sure I need the extra data.
