Maybe it would be helpful to build up the knowledge of what is and what is not compatible. I know the sliders are a big pain point for Paragon.
- Builders may start with PMW sliders, then switch to a different brand slider (which are not compatible)
- Production brands may make their own sliders (example: kona unit)
- Cast sliders may look the same, but use different inserts
For example, this thread shows the Paragon insert fitting to the Allotec slider. But from what I understand, the thickness is not correct, so the axle spacing will be off. @mark_pmw I remember you explained to me in person all the nuances of the PMW slider, could you clarify?
Obviously, it’s best practice to use PMW sliders with PMW inserts. To be clear, there is nothing wrong with using cast sliders or designing your own sliders. More options creates better bikes!
