I just put a Nashbar sourced Ergon SR3-L on my '02 Allez. I took measurements from the old saddle for location. On the first ride it was very uncomfortable. The surface transition from vertical to horizontal, was very sharp compared to my old Specialized. I moved the new saddle forward about 1/4", and its all good now. A little firmer than the original, but so far so good, especially at $25.
