Sella Italia Turbo. They reissued the Turbo saddle a few years ago and I scooped up two of them. Been using this model on two of my bikes since 1985. Flat and frim. Works perfectly for me. Specialized also has a flat saddle as does Fiziks and Prologo. I forget the name of the Prologo model, but the one that came on the Caad10 was a good choice for a flat saddle.
