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!

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.

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.
