From the golden age of the rigid frame

Just before good quality friction-option top mount shifters disappeared in the beginning of the 1990s we were able to remove the under-bar shifters and saw off the shifter mounts to retrofit the old reliable shifters onto mountain bikes with butted chromoly frames, nice all-around frame geometry and cranks with the newly reinvented round chain rings.

The Rockhopper pictured above would have come with a rigid fork. Rockshox were still an after-market modification adopted first by aggressive riders who were beating on themselves and their equipment in the quest for speed on rough terrain. The $4,000 wonder bikes of today were not even science fiction back then. Riders rode bikes of steel over landscapes of natural stone and dirt and mud. Within a couple of years we would start to hear about the aerial mazes and jungle gyms in places like the Pacific Northwest, but for the moment we rode on what we found nearby, adapting our tires, riding style and expectations to local conditions.
These shifters will not be temperamental no matter how long they've been sitting around. I remember Maynard Hershon whining about primitive shifters in an essay just a couple of years after this bike was new. He was praising the new brifters Shimano had inflicted on the world as a step long overdue to bring bikes out of the 19th Century. I admit I do not long for downtube shifters on my road bike, but I've halted my evolution at barcons.

If this bike had every piece of technological puke the industry had available the refurbishment could cost another $50 or $100 to put on seven-speed compatible parts much cheesier than the original equipment. Seven speed is now below the sludge in the bottom of the barrel in the era of ten- and eleven-speed cassettes.

Check out the forged crank with individually replaceable chainrings. This on a bike that cost about $500. By mid-decade, Specialized was leading the way in cheapening once sought-after models like the Rockhopper to extract extra profit from customers who bought the latest version on the reputation of the earlier ones.

Not everything on this old beauty is pure gold. The original brakes represented an unfortunate mutation on the way to better cantilevers and even better linear pull brakes. When we put the suspension fork on, we replaced the front brake with a decent low-profile cantilever, but the rear set are original. And the brake levers themselves are still the old full-hand type, not the two-finger levers that came to prevail.

The one-inch steerer tube limits options for a new fork, but if someone wanted to return to a rigid fork I bet there are nice castoffs kicking around. The frame was built for a shorter fork than the Rockshox Indy it has now. All the good old chromoly forks can't have been melted down for paper clips already.

It's nice to see something come out of mothballs besides dead moths. New rubber, a couple of cables and a set of brake pads and this thing will be ready for fun.

I'll never give up my dad's (primitively) lugged Trek 930, from circa 1993.

Even though it has that odd duck of a 1 1/8" threaded steerer.

With 1 1/8" you can convert to threadless. I did that on my Gary Fisher because it was the easiest way to have lots of options when I was customizing the stem and bars. A Surly 1x1 fork matched nicely.
