Does all this stuff mean anything?
Assuming all parts are original
RD is 87 manufacture (could be other years, but that's all that's known)
VeloBase.com - Component: Shimano RD-L532, Light Action
FD could be 84-88,
VeloBase.com - Component: Shimano FD-Z204-HS
Shifters are 88+ according to this.
VeloBase.com - Component: Shimano SL-S434
After some evaluation.. I slightly have to change my assessment.. it's 87 or higher assuming those components are OEM, despite the fact it has nutted brakes and 27" wheels, the paint job still points to 86 or higher to me, but with the components listed 88 seems a lot more reasonable. Also, with the basic 4130 for that era, it would peg it as being low-mid in the lineup 2400's etc were using Tange
#2 or Infinity in about the same time frame. I will be adding your bike to the Sekai database if I can ever determine a possible model...
Oh and is it a 12 speed?
