I have this FSA crankset. One arm says BB30. One has a logo of 386. The diagram is the measurements. It's probably a 2012 model based on what I can find.
Blue ink is the horizontal distance measurements. Red is the vertical measurements. The 2 distances on the bottom are the full length in Blu and the usable length after seating the arm.
The spindle is too short to be 386evo. It came with a press fit ceramic bottom bracket.
What the heck is this? I have a 73mm threaded bsa bottom bracket that I'd like to install this into but there simply isn't enough length. I don't know what it was made for. Never encounred a spindle this short. Any info is appreciated. I have googled the poo out of this already. Ai failed me. Ai did however mount this crank to a wr450 and put Mr T doing a double back flip on it, so there's that.

BB386. BB 30 is for a standard width road bottom bracket (68mm) with 30 mm diameter spindle. BB386 is wider shell, 86.5mm. Also had a 30mm axle
That looks like a crankset designed for the original BB30 (Cannondale) spec. The 386 is referencing the chainring bolt pattern.
