I just installed my first crankset with external bearings. It's a FSA compact crankset that came with the bearing cups. It turns out I even had the right socket style tool to tighten them down. What's somewhat disturbing is the cranks are exhibiting a high degree of resistance to turning. I've noticed that the newer cartridge style BB are a much stiffer than the old style (e.g. silky smooth Campy) but this setup is easily double the resistance of even a cartridge. I doubt I could get the crank to spin freely more than one revolution.

What should I check on the install to verify it's working correctly?

Thanks!
