Pinarello Pista identification help
 

Hi all!

I just happened to find this beautifull and small (52x52) Pinarello Pista frame for me. I just need some identification help with it. Frame have been re-painted and decaled. It's a defenetly Pinarello, but what model, what year and what tubing it might be?
It is not SLX as the sticker says, but it sounds and it is bit lighter than my old SL tubed frame. Takes 27.2mm seatpost. Came with nice chromed unicrown fork with pantos. Bare frame weight's 1780g and fork 660g.
