What tools will I need to take out a triple Cyclone crankset and put in a fsa Omega compact crankset? Any helpful advice?
Thanks

You'll need a 8mm hex key and a crank puller to get the cranks off.

Then you'll need whatever tools are required to remove your old bottom bracket (depends on the bottom bracket) and to reinstall your new one. The compact double will need a shorter spindle length than your cyclone triple.
