I realized that when I try to reduce the saddle length from a standard 270mm to 240mm (e.g. Specialized Romin to Power saddle for example), the saddle length adjusts by chopping the rear of the seat. But what if I want it to reduce the length from the front? IS his possible?. I realized that by only chopping the rear of the sadddle, I cannot get the acutual saddle set-up (rail posiiton on the clamp) that exists on a bike I have measured. The Saddle setback should read 2-3cm less than what it actually does when the saddle is reduced only from the rear (the setback remains fixed on the original saddle length.
Hope you can help!
