Little bit of trivia here. I started working on bikes in the early '80s and acquired tools for everything including BB and HS, numerous cone wrenches and pullers. With modern bikes, some of the tools became more or less obsolete.
Then, I bought a late '70s Italian bike, all Campy NR, and had to dig out all of these old tools to work on it. I'd forgotten that I even owned some of them.
Anyway, back then, I did everything from pressing races to building my own wheels and never thought a thing about it. Now, I find myself using the shop more than I ever did back then.
