Greetings Cyclopoids!

I am the proud new owner of a Cherry Red Bridgestone RB-2, 60cm, which I understand is not worth anything more than $200. The Reno Bike Project made a pretty profit on me (bought it for $275) and I am glad, I love that place. Anybody within 100 miles would do themselves service to stop in and rifle through the bins. The value of the joyful exuberance for cycling I have rediscovered more than compensates for any dollar I paid over the "Blue Book" price.

I am hoping that somebody can help me with identifying the year and other origins of this bicycle. Under the BB reads: M9J 27987. It might have a dash: M-9J 27987.

Trying to get a photo up, but the internet is failing me. Cherry red frame, yellow and white stripes that are above and below the vertical lettering "RB-2" on seat tube. Synergy in caligraphic letters on the top tube. Looks like Suntour XCM front and rear derailleurs, NGC brakes. I am starting to figure that the frame may be the only thing that is Bridgestone original.....

At the base of the seat tube are stickers: Tange MTB for the tubing, Made in Taiwan.

Any clues would be much appreciated. Thank you! Tk
