Funny, just saw a Hambini youtube about SRAM/FSA BB. You might consider adding a wavy washer to the
spindle, perhaps inside of the R side of the spindle, assuming one is not there already. I don't think it is
dangerous per se but wear rate will increase a bit. A 1-1.5mm spacer addition to the inside of the R side of
the spindle (drive side) is an alternative if you already have a wavy washer in place. 24mm spacers in
various widths are readily available.
I have this "Thing" in my Spindle and i noticed, im the only one that have it compared to other sram omnium people. And it also acts like a Dust Cap for the bearing. With this, i should still install a wavy washer?
