After a two year absence, it looks like Bianchi will reintroduce the Boron steel Pinella frameset in 2009.
I don’t have information on the 09 model, but the sub 3 pound Pinella has been among the lightest weight steel frames available. Though there are concerns with durability — the light weight comes from paper thin tubing — when built up the Pinella frame makes for a fantastic looking bike that handles well at high speeds. It will be available as shown in the classic Celeste color with black graphics.
