I've set up triples on Spearfish' for customers... Not FSA but it shouldn't matter what brand you run, totally works...
here's my findings. if you use a FSA triple crank, even though the instructions say to not use the 2.5mm spacer because the spearfish is a 73mm bb and the spacers is fro 68mm shell's, you do have to use the spacer because the 4 bolts that hold the 22 chain ring on, rub on the outside shell of the fish and grind the metal off.
this will leave just barely enough room for the non drive side to tigthen down and then tigthen the pre load nut.
piece of cake.
i knew something wasnt right when it wasnt spinning freely and i was thinking it was the bearings.
It's already been confirmed above but I run an FSA V-Drive on mine. Albeit now running as a 1x10!
