I have bikes A and B set up exactly the same. On bike B I pushed the seat back about 12 mm. When I took bike B for a test ride I felt that I had more power and I was using more muscles esp. in my butt and hams. I felt really good on ole B.

I then took bike A for a ride and I felt that I was using only my quads.

Would 12 mm make that much of a difference in producing what I felt was more power esp in the hills?

Also, in order to get bike A to where bike B is, I would need to push the saddle as far back as it will go. Will this damage the saddle rails?

Thanks for your feedback!

The seat tube angle would also be an important factor. A relaxed angle would also place the seat was farther back, all other things being equal.

Slide back on the saddle for more power when climbing. Well, guess what you just did? However, sliding back will compromise your spin, so it may not be a thing you want to permanently do. Adjusting your saddle all the way back should not be a problem with a quality saddle, though some units may not be able to take the punishment, particularly for heavier riders who don't rise up out of the saddle for rough spots.
