All I can say is that an 80's Panasonic frame deserves better that formulas laced to deep V's. What kind of hubs do you have currently.

Honestly, that thing needs a nice set of Superbe Pro hubs laced to a set of Araya Tubbies. That's the way to go. Panasonics were such amazing (and underrated) bikes, that thing needs to shine. As for bars, I would personally go with TT bars, more practical for the city. Find a set of Cinelli 84 TT bars for it.

That's just my opinion.
