Exploded Shimano parts diagrams for a 1987 Rockhopper

I remember 1987 as a real turning point for mountain biking. Sure, they'd been introduced years earlier, but by the time 1987 rolled around, all the major bike manufacturers vastly expanded their selection of MTBs (or ATBs as they were sometimes called back then). Couple that with ads and articles of John Tomac and Ned Overend starting to outnumber those of Greg Lemond or European pros and you couldn't ignore the ATB market even if you wanted to.
Specialized was one of the granddaddys of mass-market, mass-appeal ATBs and their 1987 lineup doubled their previous year's offerings. In addition to the venerable Rockhopper and Stumpjumper, they introduced the StreetStomper, a 'light duty' ATB meant for folks who liked the upright riding style but were sticking mainly to paved roads, and the HardRock, which essentially lowered the price of admission to the ATB game if you couldn't afford a Rockhopper. There was also a fifth offering, the Stumpjumper Team that was arguably one of the best money could buy at the time.
Anyway, a couple months back, a valued blog reader hooked up yours truly with a scanned copy of the entire 1987 Specialized catalog (Thanks, Greg!). As a show of gratitude, I sent him the exploded diagrams for all the Shimano components on his 1987 Rockhopper, posted below for your browsing pleasure.
