You are buying a used vintage 1988 Bridgestone Trailblazer MB-4 mountain bike.  The MB-4 was the nicest of Bridgestones TiG weilded Tange butted steel tubing bikes, offering a full Shimano drivetrain.  This particular bike is in ok shape and with a little work could be a great riding bike.  Currently the rear thumb shifter internals are broken and although you can shift through the gears once you release the lever it will shift back into the hardest gear (we'd advise replacement of the shifter).  Outside of this, the bike is in good working order although it has not been tuned by one of our shops mechanics.  Aesthetically this bike has some areas that could use some attention, particularly along the top tube and at the headset uppers and stem.  The remainder of the bike, including the decals on the down and seat tube are still in pretty good condition.  Please see photographs for details.
