    1987 Bridgestone MB-1 Restoration Project - Requesting help from all you experts!

    What's up homies! Picked up (what I think is) an '87 Bridgestone MB-1 (pic attached) to work on as a project and I need some help with specs.

    The previous owner listed it as a '93 (which I'm sure it's not) and he "upgraded" the fork to a rockshox but doesn't have the original fork - does anyone know the compatible specs/size I need to find to make the swap back to a rigid 1" fork?

    Ideally wanted to find a Lugged Bi-Plane or a Tange Cr-mo - let me know what you guys think!

    Thanks in advance for all your input - appreciate the assist!

    I think Double Century knows about this bike/year. Does this link have any good parts for you? https://www.boisebicycleproject.org/...idgestone-mb-1

    courtesy bump. My gut is you should find a complete '87 frameset
    **Merry Christmas**

    If you want compatible specs then a tange fork will fit nicely. 395mm axle to crown, aheadset steerer and any unpretentious stem in the length that fits you will do the job. I am all for it.
    If you want restoration then the search and charades begin.. unless you have too much time on your hands and an obssessive drive that must be attended i suggest keep the compatible specs motif and ride your bike.
    WTB: Bomber Z2 1 1/8 steerer, in good to excellent shape OR bomber rebuild kit.

    @805mtb Hey yeah thanks for the link - I actually checked it out and commented on that post regarding the stem as well - haha. I didn't see any parts on there, however I think I'll just go with a nice Tange Fork with similar measurements as the fork on the bike. Hopefully it fits!

    @colker1 haha, I actually already have a (pretentious) stem from an older build that I need to use but yeah, let the search and charades begin indeed. I've been searching for a 26" tange fork on cl, ebay, etc. and i've found a few that are just way too expensive (almost the price paid for bike) I do want to get a nice bi-plane lugged fork on it if I can find one for decent price. It'll definitely be a slow restoration, no rush to ride the bike - thanks for the reply!

    That model had essentially the same paint job for several years. In 1989, the fork was a Koski Dura-Trac. Keep that one on your search list for sure! It's probably easier to find and superior to the biplane in many ways, and will look more "correct" too.

    I've had a 1988, 2 1989s, and a 1990 MB-1 and at one time had enough parts to build another '89 if I found the right frameset. Now I only have a few parts and a 1989 Koski fork referenced above, which is destined for my klunker.
