PLANNING ON A NEW BUILD

SURPRISE

IT’S ANOTHER JAPANESE BIKE

It’s a Panasonic frame that I can’t positively identify. I passed on it before twice because

a) It’s been repainted, so I can’t really KNOW if it’s double butted chromoly or something low end, heavy, and cheap

b)There’s no fork included

But now that I’ve researched more into vintage Japanese frames, I’ve realized it’s something REALLY GOOD.

It has Panasonic forged dropouts with axle adjuster screws, a cast seat lug, top tube cable guides, oval-to-round flattened chainstays, a bottom bracket shell with points rather than flats, under-bottom-bracket cable routing with guides, an under-chainstay cable stop for the rear derailleur cable, brazed-on shifter bosses, and double water bottle bosses (one set on the seat tube, one set on the downtube,)

Those details date it to the mid 80′s, since water bottle bosses, flattened chainstays and under bottom bracket/under chainstay routing didn't become a thing for Panasonic till 1985.

None of the post 1985 Panasonic low-end bikes had oval-to-round chainstays, double water bottle bosses, shifter braze ons or under chain stay cable stops. That means it’s at least a mid-high frame, made either of Tange 900 or Champion No. 2

NOW, none of the mid level frames had under-chainstay cable stops or pointed bottom bracket shells. A few had double water bottle bosses. The two top-end machines (Fitted with Campagnolo Victory) had fish-mouth cut outs on the stays to the dropouts, and this frame has domed ends, so this narrows it down more.

Based on lugs and frame design, the only choices are: Team Europe II (Columbus SP or SL main tubes, Tange chromoly everything else) Team Japan (Columbus SP/SL mix tubes, Tange chromoly everything else) DX-5000 (Tange Champion No.1) or a DX-4000 (Tange Champion No.2)

Pretty cool. I’m stoked on it.
