    new to me Vintage MTB

    My brother gave me a 1989 Cannondale MTB that he rode only a handle of times and then hung in his Barn since 1990 or so.
    I believe its an SM600 based on a few pictures Ive found online. Its a 3.0 series Aluminum frame with Mountain LX components, Biopace HP chainrings. I took it to a local shop for a tune up and its a fun bike to ride. Its in great condition with some minor scratches, its nice handling and responsive.

    Time capsule, it looks factory new.

    Best way to get into the bike adventures !! These old things rock, very solid and capable.
    Mine is a 91 Specialized with the biopace ring.

    Thats a really modern lookin frame for an 89! My Hardrock is a 93(ish), and yours looks like it was designed after mine.
    I like that "computer designed" was a selling point back in 91. Find me a Shimano crank that isn't!

    Its just a nice bike overall. The owner of the LBS i tool it to to get tuned up told me it was one of the early examples of US made aluminum frames, apparently Cannondale even ground down the welds to blend and smooth them in. It looks really really clean.
    I even have the receipt and owners manual .
    The whole computer designed thing must have been an HP desktop calculator w tape drives😁

    "Ground down the welds" is a tad extreme...

    They used a funky method, TIG torch, with a MIG style wire feed, allowed them to dump material into the puddle and avoid the *stack of dimes* traditionally associated with TIG'd aluminum.

    They would take an abrasive mini belt sander and clean up the weld surfaces to smooth things out, but yeah, no die grinders required.....

    Sweet lookin' rig, I agree, time capsule fresh and a fun bike to get out in the woods with!

    Ya, I wasnt sure how to describe how the welds were blended in so cleanly. The process you described was most likely too expensive to continue.
