BB washer orientation
My FSA Comet crankset has two identical washers, on each side of the BB. One side of the washer has a groove along the interior perimeter, as seen in the first pic.
In order to avoid any confusion regarding the orientation of the washers, the is an "outside" label on side 1 of the washer. Now, this doesn't work for me, as I don't understand if they should face the outside of the crankarms(as the washers come with the crankset, not BB), or to face outside of the bike. These are the two sides of the washers:





And here is a pic of the BB, showing the contact surface between the washers and the plastic caps on the drive side and non drive side.



As you can see, the non drive side cap is flat, so I imagine I could install the washer any way. But the drive side cap has a elevated portion that would fit the groove on the washer.

So, how should the washers be installed ? A or B ? Does the "Outside" label make more sense to you ?
