Given The Choice, I Would Ride...

Having spent four decades as a devoted cyclist, and having worked in bike shops, I've seen lots of bikes come and go.  I have worked on bikes, parts and accessories made by companies that no longer exist (or, in some cases, by people long dead or who stopped for whatever reasons).  Some richly deserved to be tossed into the dust pail of history; others should have been put in the recycle bin or, at least, the parts box.  

Of course, I took a few "test" rides on interesting bikes I repaired, maintained and assembled.  But there are many more that I never got to ride.  If someone asked me what bike, no longer made, I would ride if given the chance, I'd have to spend a lot of time thinking about it.  A classic velo from a constructeur like Rene Herse or Jo Routens would be high on my list.  So would something from Jack Taylor, especially a tandem.  (Of course, I might not be in a position to truly appreciate it, as I haven't ridden tandems very much!) I'd also be curious to try an early Schwinn Paramount or Colnago as well as some bikes from Americans who built bikes for the six-day racers.  Finally, I'd like to ride some very early Mercians (they started building in 1946) and compare them to more recent ones and, of course, my own.

But if someone were to ask me what part or component I'd like to try, the answer would be much easier:  a Nivex derailleur.  I have grown especially curious about it since "The Retrogrouch" wrote a post on his blog about it and in the most recent Bicycle Quarterly, Jan Heine described the one he installed on his "Rene Herse", built in 2011.  Even he admits that its advantages weren't worth the time and effort he had to put into finding parts for, and rebuilding, the mechanism.  Still, his and "Retrogrouch"'s description of it have fascinated me.

I actually saw one or two--or, at least, derailleurs that closely resembled it--when I worked in shops and the first two times I toured in France.  It makes sense:  Those tours were in 1980 and 1984, and I started working in bike shops in 1975.  Dedicated cyclists, especially in Europe, have tended to keep bikes they like for longer than people keep cars and other items.  So it makes sense that there were still cyclists--mostly of a certain age--riding on bikes from the 1930's, '40's and '50's, when the Nivex was produced.  And, because of its rugged construction (mostly from steel) and design (mounted under the chainstay), it tends to last a long time.  

I think there are several reasons why they fell into disuse.  One, of course, is that the supply dried up.  But more important, once Campagnolo introduced its Gran Sport derailleur--one of the first parallelogram derailleurs made to mount on the rear dropout--bike builders made their frames with dropouts for derailleurs like it rather than the bracket brazed on the chainstay that Nivex and derailleurs like it required.  And other derailleur makers, most notably Huret and Simplex, followed Campagnolo's lead.  Also, as more bikes were spec'd with derailleurs that mounted on the dropout, and more cyclists rode with them, people--including mechanics--forgot how to use, maintain and repair the Nivex.  Finally, as production of Nivex derailleurs and others like it ceased and it fell into disuse, parts for it--and, just as important, the hubs, freewheels and companion components that maximized the advantages of the derailleur--became more difficult to find, especially in the days before eBay.  

(These days, you can go to eBay.  But if you do, be prepared to pay for Nivex and other classic French parts, as they are prized by Japanese collectors!)

From what Jan Heine and "The Retrogrouch" have said, the Nivex derailleur offered all of the advantages other derailleur makers would later try to achieve with spring-loaded top pivot bolts, dropped parallelograms, slant parallelograms and indexing.  That is the reason I'd love to try one.  But I don't think I'd order a bike, as Jan did, that's made for it simply because of the difficulties I mentioned earlier.  

SunTour S-1

One of the few recent attempts to make a derailleur that, in any way, mimicked the Nivex is the SunTour  S-1 of the early 1990's.  "Retrogrouch" said that, to his knowledge, the only bike to come equipped with it was the 1993 Schwinn Criss Cross.  (My Criss Cross, from a year earlier, had SunTour "Accushift" derailleurs and indexed levers mounted on the handlebars.)  Even though, from all accounts, it worked well enough, shop owners and mechanics complained about it and customers didn't want it because it differed from the standards of the time.  Plus, Shimano so thoroughly dominated the market by that time that any other company--especially one that was on the ropes, as SunTour clearly was by that time--would have had a difficult time introducing a "new" concept.  (Most people at that time didn't know about Nivex.)  As far as I know, nobody bought the S-1 as a replacement part because it couldn't be retrofitted to most bikes, which lacked the necessary brazed-on chainstay boss. Perhaps one could improvise a mounting bracket, but who would have taken the time to do that?

Anyway, I would like to ride a Nivex one day.  Jan, if I'm ever out your way, could I borrow your bike for a while?  I may even give you my PMP crank for the privilege! ;-)
