Bridgestone MB
Question
I have an opportunity get a '91 Bridgestone MB-6 for about $100. I know that it was the entry level bridgestone and was only $400 new, but it appears to be in good shape and my plan is to convert it to a singlespeed - so the lower end components won't be that relevant, and those that are left I'd consider upgrading (stem, bars, levers). Speaking only about the frame itself - would this be a good candidate for this kind of project? It's TIG-welded Tange double-butted cro-mo. I'm curious how much "worse" it was than the higher level bridgestones of this era, build kit aside. If you know about this and care to reply - Thanks! 1991 Bridgestone MB-6 Trailblazer in Solid Black Frame-19.3" (49 cm) Tange CrMo Double Butted MTB Tubing Derailleurs- Suntour XCM Shifters- Suntour Accushift Plus thumb shifters Cogs- Suntour Accushift Plus 7 speed (13,15,17,20,23,26,30) Crankset- Deore LX 3 speed (24,36,48) Chain- Suntour Accushift Brakes- Dia-Compe XCM alloy cantilever Levers- Dia-Compe XCM short lever Wheels- Araya VP-20 36h presta valve Hubs- Suntour XCM , sealed, QR front and rear Tires Ritchey Force 26x2.0 Seatpost- Kalloy SP-200 alloy, 300L Seat- Avocet Touring Stem- HSIN LUNG MTS-115G-1, T-bone type, black Bar- HSIN LUNG MTB-110, 560w, black Headset- CP Grips- Ritchey True Grip Braze-Ons- Bottle mount (2), rear rack mount, slotted cable stops |
Also, for perspective - I just got back into mountain biking about a year ago and have a Cannondale SL2 HT Trail 29er.
My previous rigid bike was a trek 820 which i had for 10 years. |
Look it up your self. :)
Here is a link to Bridgestone catalogues:Bridgestone Bicycles My first mb was 1991 Bridgestone MB-3. Still have it. |
Sounds like a good deal to me. Actually, the suntour stuff on that bike is pretty good. It's incompatible with Shimano and I think sells well as the supply of 7 speed accushift parts is low, particularly cassettes.

All of those Bridgestone's shared the same frame geometry,---Grant Peterson was of the mindset that even beginning racers wanted a high-performance bike too
I I had one and pored over tons of magazine articles in those days trying to find something better in my price range The bike was a bit heavy, but a lot of this was inexpensive wheels and generic hardware (seats, stem, post). --- the frame is also no lightweight, but was a true to life Norba geometry racebike at a price i could afford as a 17 year old twerp |
From the catalog, it appears to have vertical dropouts....not ideal for a single-speed conversion. Unless you get really lucky, you'll have to have a chain tensioner hanging off the back-end, which to me, spoils the whole concept of a simple, straight-line singlespeed.
Look for a similar era Specialized Rockhopper or Hard Rock. They are plentiful and cheaper than Stumpjumpers and at least some of them had forward facing dropouts that allow for chain tensioning. |
