I'm going to either make or buy tool(s) when it comes to removing and reinstalling new bearings. I haven't been impressed by the shop that sold and is servicing my bike. They reinstalled the crank after re-greasing the bearings and didn't use the wave washer, so I've ordered one online (cheap). I like maintaining my own bike but I'm not made of money and don't like buying expensive tools.
I've found that BB30 maintenance to be quite technical and fortunately FSA has great technical documents on their website.

This forum blows for accurate information on high end road systems.
The only current gen ext bb crankarms that are selfextracting are srams. Neither shimano nor campy's are self extract for road. Lets compare
Campy
1) 10mm hex
2) external bottom bracket tool
Shimano
1) 5mm hex
2) Shimano preload cap tool
3) External bottom bracket tool
BB30
4) Hex key
5) BB30 bottom bracket bearing installation and removal set
In addition the BB's do NOT need to be serviced regularly, as with any other BB system out there.
