I am not that old.....but the memory is going
What was the title of the funky bike info/repair book from the early 70's
I had weird cartoons (like one of person with a big bottom when talking about ashtabula cranks)
It was a basic book at the time of the bike boom and 10 speeds were new and unusual.
The book loved suntour and thought huret plastic deraillers were junk as I recall.
