Hello all. I need help identifying a bicycle, again.
Here is what I know:
Serial #: 7E00449
Panasonic Drop-outs (Front & Rear)
Crankset: Shimano 105
Shifters: 7-speed Shimano 105
Brakes: Shimano 105
Front Derailleur: Shimano ?
Rear Derailleur: Shimano 600
Rims: Mavic
Hubs: Shimano RX100
Headset: Generic
Seatpost: 26.8mm
BB-TT (C-C): 55cm
TT (C-C): 55cm
Weight: ~23-24 lbs on my crappy fish scale
The serial # indicates that it is a 1987 model, but beyond that I'm not sure. The guy that I bought it from was told that it is a DX-4000, which would make it Tange Champion #2. I have heard that the Tange tubing sets use the same size seatpost. Is that true? It has been powder coated, I think, so there is no original paint or decals. Is there any way to tell the exact model?
