    Maybe the earliest MTB with Disc brakes from 1988

    Or maybe you have evidence of something even earlier you want to share..

    This one was made by JP Morgen from San Francisco, also notice funky front end.


    I ask him, what kind of rims and how did you make the brakes..??

    I can't remember the rims, they were super light for the day though, maybe a cut down road rim? The disc was a clutch plate from an old Triumph motorcycle, the caliper was a small Grimeca, and the master cylinder was maybe kawasaki.
    jp
    I'm pretty sure this is the same bike..


    Another one even earlier one..

    Actually if I remember correctly the Skinner was not even a "Real" mountain bike but a "descender" for the Topanga hills..

    If you're like me you don't slow down enough to look at your food before eating it
    I may or may not be laughing at you.

    Glad to be of service. I took this photo in Japan at the first Japanese national MTB championships in 1984. The woman is Denise Caramagno.

    I don't know why the other photos don't display, but they seem to be linked.

    That's so cool! Wende mentioned that Denise coined, "Fat Tire Flyer." I think it's a great name and it's nice to see these old pictures of her. I think Wende posted a great picture of herself and Denise as well.

    Not a MTB per se, but production discs have been around for quite a while.

    1977 Sekine GTO

    I don't know for sure, but I think that's more of a drag brake for tandems operated by a thumbshifter or barcon. Much like the Arai tandem drag brake. Just going off memory here though... I don't know much about tandem stuff.

    Drag brake indeed. Pulled from production due to pad material failures. At least that what I've read on the Net so it must be true.

    Not useful for mountain biking. The open construction was not at all resistant to mud and crud, and the precision surfaces would not stand up to much intrusion.. The specimen den haag saw was on Neil Murdoch's bike ca. 1980. Made for tandems, very expensive, and except for that example I never saw another one on a MTB.
