I know that my 84 Trek came new with cloth wrap; also thin and thick foam padding was available which I tried the thin and wrapped it with cloth around about 86.

There's no need to go vintage unless you want to. The passion would be more for conversation during group rides; I ran into a guy about 5 years ago that had an old early 60's racing bike I can't remember the name of but it was in great shape, and he went so far as to ride with beechwood rims! The beechwood rims according to him was what came on the bike originally; and talk about a conversation piece, everyone on the ride was admiring the bike and those rims even though the rims were of recent genre. I know that with cars I'm keeping my 67 Ford Galaxy 500 Conv vintage original, and any parts I take off to improve certain dynamics like removing the points and replacing them with Pertronics electronic points, still maintains the stock look, it's an easy conversion back to original points, and I no longer have to adjust points ever again; the radio is stock but there's a hidden better stereo but sacrificed some sound since in 67 there was only one speaker in the center of the dash so I replace but kept the original speaker for one really nice speaker. For the Ford it's a passion to leave the car unmolested, whereas my 79 Camaro Z28 it's almost expected to be hotrodded so the engine is now a 580hp 350 instead of the stock anemic 170hp 350! I also have a cowl induction hood that didn't come with the car originally but I kept the original hood in case someone wanted the unmolested hood with the fake hood scoop when I sell the car, and it's stereo and speakers were severly upgraded, but I have the original 8track stereo again for the purist.

All that to say, if a person wants to leave it vintage then by all means do so, it's actually more fun going vintage; but if you do modify it keep the original vintage parts so you can convert it back if you ever need to.
