But
even for late '80s, isn't that bike in the OP a bit awkward (and old-fashioned-- er, anachronistic
for the late 80s??). That book, from which the image was taken, was quite a popular title, and pub'd by Bicycling Magazine [MAGAZINE ... luv that word!]. You'd think for the few photos that were included (in that book), they'd use some piece of kit with more agreed-upon concepts ... NOT like those brakes, and that sprocket? WTF!!?
