I am seeing used CWD saddles with different dot-to-dot measurements, but I have always read that CWD has one tree size (other than AO) and the panels adjust the fit. Is it possible there are different trees or are the wider tree measurements (with identical panels) an indication that the tree has stretched with time and use? For example, I have seen a couple 5" trees, but they are not stamped AO, and then I have seen AO saddles with 4.5" measurements.
Also, does anyone know if different CWD models have different trees (not talking about the carbon trees)?
