Spotted this late last night on CL for $40! So I crossed my fingers and called this morning... he still had it! Went and picked it up at lunch time. Looks to be an '87 by the dat codes I could find. ST measures ~37cm, TT is 46cm, and a 26" stand over. Couple scratches and the tires have good tread but rotted sidewalls. Overall in good mostly original shape. I've changed the saddle (had a cheap kids MTB saddle that didn't mach at all) and replaced the torn foam grips with some nice new tape. Still just a little big for my 9 year old daughter but with the seat slammed she can peddle it and she's smiling HUGE . So as long as we stick to the trail and she doesn't have to stop much, it's "ridable" . I keep underestimating how tiny she is! She'll grow into this a lot faster than the 47cm RB-1 I picked up last summer. My 15 year old does fit that and she's even attempted one ride with me but she's just not loving the idea of a road bike like the little one.
