John, et al:
I was racing in the 60s, and at the time, the Paramount was far and away the bike to have! I custom ordered a Paramount track bike in 1962, and still have that bike. I also have 5 other Paramounts, two more of them from the decade you refer to, and not one of them have had the BB re-taped. In the entire 45 years I've been involved with Pro bikes, I've never even heard of needing to re-tap the BB
I'd suggest you recheck your source, I'll bet that he's exaggerating the situation based on one or two random Paramounts that he is personally aware of.
