    Help identifying late 80's-early 90's bike

    Hi all,
    I got a new (for me) bike i'm trying to identify. The decals say Marin, but i'm pretty sure it's not
    All the components are in very good shape and consistent with a late 80's production date - Deore II derailleurs, XT shifters, U-II brake, so i believe they were original on the bike

    Interesting features
    - chainstay mounted U-brake
    - magnet doesnt stick to the frame: aluminium? doesnt look titanium to me
    - 7 digit serial number on the head tube

    Any ideas?

    The rear drops and stays look steel, in that they they don't look like aluminium. They look like standard steel ends that are slotted into the stays and brazed in place.

    The head tube welds don't look like the stack of dimes look you get with properly welded aluminium, and certainly not the neat tight welds you get with ti.

    The brake protector and/or kickstand mount hanging off the chainstays is unique. Hopefully someone recognises that feature.

    Either way, decent components!

    They're also non-magnetic, even if they do look steel. Only the front fork is steel

    Steel can be non magnetic, I have certainly come across some steel spokes that wont stick to a magnet.

    Im not a fan of that brake location...braking forces trying to rip the brakes off the bike rather than pushing into the frame. Super interesting frame though, thanks for sharing!

    There are plenty of reasons to dislike the brake and location. But in particular, how are the forces there any worse than a front brake? The forces on the front are trying to rip it off to?

    Just playing devils advocate and curious 😊

    Yeah, the seat/chainstays and the bottom bracket shell look too small for aluminum as well.

    Non magnetic would point to stainless steel tubing which very few mountain bikes were made of.

    The stem is also from early 90s (i think)
    I couldn't see any markings on the headset

    Super odd.

    From my chair, only having the info provided here, and not knowing much of Marins history?

    All adds up to an experimental material attempt. Think, magnesium, or boron. Both would have thickish welds like that.

    Seat binder? Looks like they designed something to allow the material to not be pinched, as though that amount of constant tension and release would cause failure?

    Rear end, not being magnetic, and small diameter as it is, beats the hell out of me.

    Maybe not even a Marin, but someone got a sticker kit and tossed it on?

    It's obviously steel (and rocking some some ugly-ass welds).
    Get a stronger magnet and shave a little paint off; it'll stick.

    I've got a couple frames with integrated seat binders. Not all that out of the ordinary.

    This looks like an old Kettler Alu Rad "MTB" from Germany. Frame is made from Aluminium with glued (steel?) dropouts.

    That seems to it, Pepperman! Thanks a lot
    Even the location of the serial number matches what i've seen in other pictures of Kettlers

    Ha! so someone Marinified it.

    My next guess based on the birdsh*t welds was going to be someone rebadged a older Murray or something....
