    Anybody ever upgraded old Marin frame to disc brakes?

    Subject says it all. I like the frame a lot (2002 Marin Hawk Hill) and would love to continue using it.

    The dropout has two threaded holes 22 mm apart, presumably for mudguard and/or carrier - perfectly positioned to be a mount for an adapter. See attached picture.

    Extensive web search for an adapter and a question to Marin tech support yielded no answer. The best I found is the A2Z sandwich thingie, but I hear it has its issues.

    Any help/suggestions will be greatly appreciated.

    To avoid "obvious" replies:

    This:

    is not what is needed.

    I'm going to throw out another obvious answer: You can still use the frame with rim brakes. Put a disc on the front if you want.

    I used one with my old Kona. I didn't have any any issues with it. Here is what it looked like:

    In case anybody is interested/cares:

    I managed to fit the A2Z adapter to my bike. Took a weekend and a couple of band-aids.

    I actually needed to file the inner side of one of the adapter "fingers" a bit, as it was encroaching on the axle.

    I also drilled a hole in the outer plate to fix it to the frame using one of the two threaded holes shown in the original post.

    Ain't pretty, but is very stable -- the additional screw made a hell of a difference -- and works very well.

    Enclose a photo for your viewing pleasure.
