I bought a Niner Air9 RDO frame as a replacement for my aging One9 SS.

My plan was to purchase the Niner Biocentric 33 EBB but...I can't find anywhere to purchase it. Can't buy it online at Niner, and my LBS can't find it either. It is truly a unicorn right now.

So I see that Origin8 and FSA make EBB's for PF30 as well.

Does anyone have experience running other brands of EBB on the Air9 RDO? It's a carbon frame so my gut tells me I need to tread lightly here...

Thanks.

Have one new in the box if you are interested?

I've only used the niner one, and it's pretty dang nice. I recall there being something fancy about how it clamps up, so it doesn't just squeeze on the outside of the shell, therefore making it the "only approved" EBB by niner. Looks like @justriddinalog might could hook you up, I'd do that!
