Barely used FSA (Full Speed Ahead) crankset, carbon crank arms powerbox (power meter) 175mm length 50/34T compact gearing BB386EVO bottom bracket size. 11 speed Shimano road standard. Awesome crank, and the power meter works great. I installed this then decided I wanted to sell the bike for unrelated reasons. No longer have a frame with a BB that will fit this. BB86/30 compatible
