Got it and installed it. Seems to be working great. My only concern, and I predicted this, there are always pieces that are not in the instructions. After removing my FSA Crank, there were three seal rings. This crank came with what looked like one. I kept the main seal that was directly on the bearing, but swaped the second one for the one that came with the crank. I didn’t even keep the third as it was only on the non-drive side, and warped.
I’m assuming it should be between the spacer and bearing and not the spacer and crank arm. This is probably to specific, but indulge my OCD. Either way, everything is well greased. And it appears to be smoother than my FSA Gossamer was.
