I just picked up a very clean 1984 Trek 510. When I got it I noticed that it had mostly Campy Victory components, headset, brake levers, hubs, crank & pedals. He had 'upgraded' to Suntour Cyclone 7000 indexed shift levers, and F & R dérailleurs. It has Campy Record brake calipers with brand new Campy pads (not complaining). He had the Campy Victory dérailleurs and shift levers put aside, so I got those as well.
Since nearly everything on it was Victory, I assumed that was what came on it originally. Of course, I was wrong.
My question is, did Trek offer an upgraded version of the 1984 510, or did the owner just swap out all the original parts for the Victory components? The Victory hubs are laced to what appears to be the original Matrix Strada 27" rims, which I find a bit odd for an after market swap.
