Anyone know if the saddle setback remains the same, regardless of the saddle's length? (270mm, 275mm, 290mm long saddles)

Thanks

In seat post selection, Set back is the distance the rail clamp is,
behind the center line of the seat post/seat tube.
The seat post design, itself.
The way the rails of the saddle are formed,
shape of their rail bend,
has more influence on how far back a saddle can be set back ,
than it's over all length.

turn the saddle Over.. look at the frame underneath.


Your other double post is here same topic

why is there more than one design for anything?

Saddle setback is the distance from the center of the BB to the nose of thesaddle, measured horizontally.

The question is:
If you normally run a 5cm setback with a saddle that measures 270mm long, wouldthat value change when running a saddle that's 290mm long? Would a longersaddle change your saddles setback? That's the question.

I prefer longer saddles so that I can slide back to stretch out on climbs or more control and descents or slide forward for more power. People with real short legs will usually prefer a shorter saddle that doesn't keep hitting them in the rear end when they try to get on or off the bike.
