The black 695 has the SMP carbon lite saddle. The grey 695 has the Forma. I just replaced the Forma with another carbon lite because the slight difference in width and length works better for me. I took the grey one on the San Diego century a couple of weeks ago and actually swapped in the Carbon Lite while waiting on a new one to be delivered from ProBikeKit just because it's that much more of a comfortable saddle (to me).
