A New Bike-Packer—Or A ‘90’s Mountain Bike?

Because I am in, ahem, midlife, I am old enough to have owned and ridden a mountain bike made around the time Rock Shox, Marzocchi, Manitou and a few other hitherto-unknown companies were bringing internally-sprung front forks to the general public.  A few bike-makers were developing frames with suspension in the rear triangle. But that feature, and suspension (what Brits called “telescoping”) front forks were still extra-cost options or modifications.

At that time, in the early-to-mid-1990s, mountain bike frames like my Jamis Dakota typically had 71 degree head angles, which are a bit more slack than road frames (73-74 degrees) but more aggressive than ‘80’s machines that, like the balloon-tired bikes from which they evolved—and many of today’s “hauler” and “rough stuff” bikes—had angles ranging from 69 all the way down to 66 degrees.

Bikes like my old Dakota, I believe, were attempts to inject some road-bike responsiveness into mountain bikes, some of which were, frankly, sluggish. But those bikes from three decades ago were comfortable and stable enough that they were often used for loaded touring (sometimes after switching the flat handlebars for dropped bars), as Trek and other bike-makers stopped making dedicated touring bikes around 1988.

Well, someone at the Dutch bike company Van Nicholas seems to have ridden—or simply recalls—one of those mountain bikes. Their new Nootau, billed as “the ultimate bike-packing machine,” is built around a titanium frame with a geometry nearly identical to a just-before-suspension off-road bike.




Of course, the Nootau’s componentry has almost nothing in common with what was in use around the time “Smells Like Teen Spirit” blasted across the airwaves. Like most of today’s new bikes, it has a threadless headset and stem, which were available but not standard.  But, unlike the cantilever brakes on vintage mountain bikes, disc brakes stop the Nootau.  Discs enjoyed brief popularity, mainly on tandems, during the late 1970s and have been revamped during the past few years.

Perhaps the most striking difference, however, between the Nootau’s equipment and that of vintage mountain bikes is in the drivetrain: the Nootau has no derailleurs. Instead, its single-sprocket crankset is mated to a Rohloff rear hub with 14 internal gears. (I’m trying to wrap my head around that: I’ve had Sturmey Archer and Shimano three- and five-soeed internally-geared hubs.

I may not have the opportunity to ride a Van Nicholas Nootau. I must say that I like its look—and relish the irony of how much its design resembles that of my old Jamis Dakota.

In Suspense--Or In Thrall To Aesthetics?

Sometimes I think the '90's were the end of an era:  when you could care about aesthetics and still buy a high-end road racing bicycle.

Today, you can get a beautiful frame from a builder like Mercian or any number of other custom makers.  But even though it can be sleek and relatively light, it's likely to be heavier and less aerodynamic than a new racing bike.  Those gorgeous frames with their beautiful lugs or filet-brazed joints and lustrous paint jobs are most likely to be steel, whether from Reynolds, Columbus or some other maker, but most racers are now astride frames made of carbon fiber.  Although I can appreciate the lightness and stiffness of carbon fiber frames, I know that their lifespan is nowhere near that of most good steel, titanium or aluminum frames.  Also, their Darth Vader shapes and surfaces are too often plastered with cartoony or just plain creepy graphics.

But during that last "golden era" for road bikes, two seemingly-disparate groups of cyclists seemed to abandon any sense of velocepedic voluptuousness.  According to Eben Weiss' latest article in Outside magazine, those riders were mountain bikers--especially of the downhill variety--and triathlon competitors.   As he notes, mountain biking and triathlon racing  came into their own as disciplines at roughly the same time, more or less independent of the prevailing cycling cultures (racing, touring, track, club riding).  Although many mountain riders came from road riding, they tended to be younger and not as bound to the prevailing traditions and conventions of riding.  Then there were those mountain riders who, like most triathloners, had little or no previous experience with cycling and were therefore even less wed to ideas about what bikes should look or ride like.

One result of that disdain for bicycle tradition was modern suspension systems.  One irony is that those who developed it for mountain bikes thought they were doing something new and revolutionary when, in fact, bicycle suspension  has been around for almost as long as bicycles themselves.  The chief question seemed to be whether to suspend the rider or the bike itself:  The former would offer more comfort and would, therefore, keep the rider in better control of the bike. The latter, on the other hand, would make the bike itself more stable at high speeds and in rough conditions: what would encounter in a downhill or on technical singletrack.


One of the earliest--and, perhaps, still most widely-used--forms of suspension is the sprung saddle, which would fall into the category of suspending the rider. Later, balloon-tired bikes from Schwinn, Columbia and other American manufacturers came with large bars and springs connected to the handlebars and front forks.  How much shock they actually absorbed, I don't know.  I get the feeling they were added, like the ones on the "Krate" and "Chopper" bikes of the '60's and '70's, so that kids could pretend that their bikes were scaled-down motorcycles. 




Around the same time as those wannabe Harleys were made, Dan Henry's (of the Arrows fame) rigged up a Reynolds 531 fork with springs which, he said, allowed him to ride the lightest rims and tubular tires even in the roughest conditions.  But the '70's and '80's saw little, if any, experimentation with, let alone manufacture of, suspended bikes or parts.

That all changed when the first Rock Shox forks and Girvin Flex Stems were introduced in 1989.  The latter defied all notions of the graceful "gooseneck" in mirror-polished or milky silver, and Rock Shox looked nothing like those curved or tapered blades seen on classic road bikes.  Then, it seemed, all sense of aesthetics went out the window--unless your idea of art is a sex toy or something that would render a man incapable of bringing any new cyclists into this world--with the Softride.




I must admit I never tried Softride:  Even though I was leaner and lighter than I am now, I was leery of mounting anything that didn't have support from below. (Read that as you will.)  Weiss rode one recently, three decades after its introduction, and found it to be "more subtle" than he expected though, he pointed out, he could have been just as, and more elegantly, cushioned from road and trail shock with a leather saddle or wide tires.  Subtract the "diving board" and Girvin Flex stem, he notes, and one is left with a rigid mountain bike like the ones riders had been riding before. 

If I had a couple of barns or garages, I'd probably acquire a Soft Ride to complete the collection I'd have.  But even if I liked its suspension qualities, I'm not sure how much I'd ride it:  I'm still too wedded to my vision of a beautiful bicycle.  There are some things I just don't want to be caught dead on.

Easing The Shock Of Gravel

 What are some telltale signs of an early '90s mountain bike?

One might be bar ends, especially those from Onza and Club Roost.  Another could be early Rock Shox or Manitou suspension (or "telescoping," according to the Brits) front fork--or a sprung rear triangle.  




Another popular form of suspension was built into handlebar stems, such as the ones from Girvin or Softride.  I never tried one myself, but I suspect they didn't do nearly as much to dampen shock--and make a ride more stable--as a suspended fork or rear triangle.  I suspect, though, another reason why they fell out of favor is that spension forks led to two nearly-simultaneous changes:  28.6 mm (1 1/8") steerer tubes replaced 25.4 (1") as the new standard, and threadless headsets became an industry standard.  Girvin and other suspension stems were of the "quill" type and manufacturers couldn't, or didn't want to, make threadless suspension stems.





Well, in the cycling world, very few ideas actually die.  SunTour made cassette hubs and indexed shifting in 1969.  I've never seen them, but from what I've read and heard, they worked well. The market wasn't ready for them, however, until Shimano re-introduced them a decade and a  half later.  Likewise, suspension stems didn't end up as road- (or trail-) kill.  A recent trend has brought them back from the dustbin of cycling history.

Gravel biking is credited for showing that wider tires aren't only for mountain bikes or beach cruisers.  It also has renewed interest in minimalist, lightweight forms of suspension.  Most suspension forks are simply too heavy, and too dampening, for gravel bikers' tastes.  Those forks also have straight or nearly-straight blades, which negate the benefits of the low-trail bikes' geometries.  And I don't know how feasible rear-triangle suspension is for a gravel bike.





During the past couple of years, some new suspension stems have appeared on the market.  Unlike Girvin and Softride, the new Shock Stop and Kinekt models are threadless stems.  The former uses swappable elastomer inserts, rather like a few of the 90s suspension forks and USE fork.  Not coincidentally, Shock Stop offers an elastomer-equipped seatpost to complement its stem. Kinekt, on the other hand, uses a parallelogram system reminiscent of the Soft Ride.





In my limited experience with suspension systems, one problem I found with elastomers is that dirt, moisture or cold stiffened them.  A mechanical system like Kinekt might be heavier, but more reliable, and avoids the problem of manufacturers who discontinue replacement elastomers (or go out of business).  I am not making any recommendations, as I have never used any new or old suspension stem.  I do find it interesting, however, that a new trend in riding has given an old idea a new lease on life.
