    Sliding dropouts dimensions

    I am looking for specific dimensions of various sliding dropouts. Can anyone spare a minute to remove theirs from their frame, take a detailed photo, and measure the dimensions? I'd like to see how interchangeable various sliders are.

    Here are the sliders that came with my Jabberwocky. They are not a Paragon Machine Works product, by the way.

    I would be curious to see how Carver, Kona, PMW, etc would match up.

    I can photo my IRD inserts. I was able to use the PMW inserts in my IRD dropouts.
    PMW was nice enough to send me a drawing with the dimensions of there inserts so I could measure and see if they would fit.

    My kona sliders measure 42mm at the widest and the OD of the bolt holes is 12mm. Measured with calipers.

    I found drawings of PMW sliders, but what I wanted to know is if the horizontal distance between the axle and the fore-position mounting bolt is shorter than the sliders that came with my bike. the goal was to see if, assuming PMW sliders will work with my bike, can I use them to effectively shorten my CLS by at least 10 mm.

    based on the drawing, I was able to learn that the axle is 22.3 mm below the sliding mounting tab. using that for scale (the printout of that PDF does not come out to scale), the fore mounting hole is about 48 mm, if my calculations are correct. that's the same as my existing dropouts, so PMW sliders are probably not going to make a difference.

    I'll try to measure the dropouts on my Marin Nicasio SS in the next few days. I'm curious about the measurements myself in that the drive side dropout on the bike doesn't have a mech hanger, but it would be great to be able to swap in a PMW or other dropout if it would fit.

    I asked PMW, and the horizontal distance between the axle and the forward-oriented mounting hole is about 42 mm. add the material in front of the hole and you have a maximum of 45 mm. the sliders that came with my frame are effectively the same size.

    my interest is a slider that fits my frame and is more like 35 mm in that direction. I could probably modify mine to that end but I need to find a friend who has the equipment to do that right.

    Here are my PMW sliders dimensions.
    **Edit, measured from the front of the slider material to the axle and the center of the axle and have the 48mm distance as well. Still hunting for the Kobe dropout from my spot. When I had the spot, I did try to fit these PMW dropouts in, one of them fit, but the other one wouldn't work, if I recall it was the disc brake side that wouldn't work due to the extra material of the disc mount not recessing into the spot system.
