yeah they were developed by Fly Bikes, hence the "spanish" bit, but i'm sure there have been quite a few different variants out there at some stage.

Those cups should take normal euro sized bearings, but I have no idea what the cups are ?  ??? :-\

Hey if the cups aren't threaded, isn't there another setup which is kinda like the profile evolution BB that actually threaded into itself from each side?

IASC or something???

Google time, I reckon...

Have a look on sheldonbrown.com

tons of info there    :daumenhoch:

def a weird size BB  :-\

stidds:
Have a search for 'Threadless Bottom Bracket', that is the kind that threads to itself.  I know YST do one but I am unsure of the sizes.
