Setback of 152 mm seems high. How are you measuring this?

[LouDeeter]

152 is exactly what you should expect with a 74 degree seat angle. I measured the seat angle at 73.8. I measured the setback with a setback measuring tool. If you have never seen one, I'll post a picture.

Well then maybe I'm thinking about saddle setback (diff between a plumb line drawn through the crank axis and the tip of the saddle. But sure, post a pic if you've got one - that would be great.

Here is the tool, made by VAR. You place the short axis on the toptube and adjust the long piece to center of the bottom bracket/crank axle. Then, align the measuring device horizontal to the center of the seattube. I make sure the toptube is level before doing it. Great tool if you use setback as a sizing datapoint. Setback gives you the distance along the toptube that is behind the bottom bracket. So, you can then subtract that from the toptube length to tell you what the distance of the toptube in front of the bottom bracket is.

While you can use the saddle rails to compensate, ideally, you'd like the saddle rails to be centered on the seatpost clamp when your saddle is in the position to give you the most comfort, power or whatever else you are adjusting the saddle to meet. Some people still use the knee over pedal spindle technique, although that has gotten a lot of critical disagreement in recent years. Also, with straight seatposts, that can change the dynamic as well. I use the tip of the saddle to the center of the handlebars as a measurement datapoint, but even that can be skewed if the reach of the bars is more/less from the set of bars from which you derived your perfect measurement.

Typically, when one says "setback", they are refering only to the relative position of the seatlug center to the BB shell in a horizontal measurement.

"saddle setback" is the plumb bob method to establish the horizontal measurement of the saddle nose to the BB shell.

The first method is best, since it eliminates the variable associated with saddles having different shapes, lengths, etc.

OK - gotcha. Thanks. I use the latter method to transfer contact points between my bikes using the same saddle.

GL with the sale. Pretty much my size which is I am watching this, and unfortunately painfully stepping away from my monitor right now....
