Exactly. Let's first find out what type of Athena crank is currently in service. In case it's PT then it'll need UT cups fitted for any Chorus, Record or SR crank (or Fulcrum crank for that matter).
Do not fit SR cups unless you are installing a SR crank. SR lacks gaskets the lower end bearings require.
I run SR cups on my Record cranks. If BB shell "closed" no reason to have those gaskets in there...only if You wanna get slower
Like you Permon I have installed SR cups on my Colnago C50 for my Record cranks - seems to fit just fine. Despite warnings on the installation manual can anyone see a problem with this setup?

The guys quoted did explain it, but I'll try as well.
Regular cups have a seal on the inner side which would resist water that entered the BB shell from getting into the bearings. Some bikes, usually older ones have an opening between the seat tube and the BB shell, so if any water got into the frame, it would migrate to the BB shell. If the bike has a drain hole in the BB shell, it's a clue.
Most modern frames are not like this, and the BB shell is isolated from the seat tube, which makes a seal on the inside of the bearing redundant. Campy deleted this seal on the SR cups to save drag.
If the frame is one where water can get into the BB, and you ride in the wet, then I'd think having a SR crankset or cups would be a bad idea.
If the BB shell is sealed off from the rest of the frame, then the inner seals on the cups really are not doing anything useful, and SR cups will be fine.
There's sometimes a buggy.
How many drivers does a buggy have?
So let's just say I'm drivin' this buggy...
and if you fix your attitude you can ride along with me.http://www.youtube.com/watch?v=GekiIMh4ZkM
