dang, I'd swear that was Drew Barrymore on the cover!
Good to see the Frank Berto article on gearing. I didn't realize that the idea of "compact" gearing existed at the time. i.e. the version that I'm familiar with uses 50-34 chainrings, providing fairly wide gears at the expense of a clumsy switch between chainrings. Frank's version used 52-36 rings, but otherwise used the same concepts.
Calculating gearing has been something useful and sort of entertaining for me, but I've tended to rely heavily on logarithms to make the calculations pretty direct. I'd like to think that Frank did the same, but I give him credit for trying to make it comprehensible to the average person. I'm not sure I'd have the patience for that.

Yeah, me either.
I'm kind of fond of the advertisements for products that never really made it.....or at least as far as I know.
