Holy V, Jubilee!

In October 1964, Tetsuo Maeda filed a patent application in Japan for what would become, in my opinion, one of the two or three most important derailleur innovations in history.

It was the brainchild of his chief designer, Nobui Ozaki.  He was no doubt trying to make a derailleur that was easier to shift and shifted more accurately than the ones available at that time.  Did he realize that it would influence derailleur design for the next half-century?  Did Maeda, the owner of the company that employed Ozaki, know that for two decades, other derailleur manufacturers would wait, with bated breath, for his patent to run out?

Well, both of those scenarios came true.  You see, the patent Maeda filed in his home country--and a month later in the US--would cover a design still used today, in one form or another, on any rear derailleur that has even a pretense of quality.

I am talking about the SunTour Gran-Prix.  Over the next few years, SunTour would refine its design.  For one thing, it would replace its original single-spring design (The same spring that operates the parallelogram also tensions the chain cage.) with separate springs for each function.  And steel parts would be replaced by alloy ones, which in turn would become more sculpted and rounded.

The result was that the 1964 Gran Prix

would evolve into the first "V" derailleur in 1968.

I would put one of those on one of my bikes.  I mean, how can you not love a derailleur with those pivot bolts?

Of course, the V was further refined and became the V Luxe.  One thing I find interesting about the V and V Luxe is that they were lighter than most derailleurs made at the time--or even today.  

The V, according to Michael Sweatman of Disrealigears, weighed 218 grams.  That is only 13 grams (less than half an ounce) more than another influential derailleur that came out exactly 50 years ago

yes, the Campagnolo Nuovo Record--which, of course,was a refinement of the earlier Record and its progenitor, the first Gran Sport parallelogram rear derailleur.

For comparison's sake, the 1968 SunTour V weighs almost exactly the same as a Shimano Ultegra 6400 (introduced in 1988), 6401 (1992) or 6500 (1998)--or the Dura Ace 7402 (made from 1989 to 1996), all of which are in the 210 to 220 gram range. Later DA rear derailleurs (the 7700 series onward) shed 10 to 15 grams--and that with the use of a titanium upper pivot bolts!

The funny thing is that no matter how light a component is, someone wants it even lighter.  So I guess I shouldn't have been surprised to find this

I mean, how much weight did those holes take out of that "V" derailleur? 

I guess I shouldn't be too critical, though.  After all, not only was the Campy NR drilled out--or, sometimes, slotted in its parallelogram--so was the lightest rear derailleur of them all:

In case you were wondering:  The Huret Jubilee weighed 145 grams--before anyone touched it with a drill, mill or lathe!


  1. I'm old enough to remember the importance of Suntour derailleurs. My first 10-speed, a 1973 Motobecane Mirage, was fitted with Simplex derailleurs and shifters. If I recall correctly, the Simplex equipment broke and I replaced them with Suntour equipment before the end of my freshman year in college. My wife's 1975 Raleigh Sprite also received an upgrade to a Suntour rear derailleur at some point. My early 80s Raleigh Super Course was Suntour equipped (including the dropouts) and the derailleurs and shifters gave me decades worth of trouble-free service. When I sold the bike earlier this year, I had to swap out the rear derailleur because it was acting funny. I also swapped out the shifters because I had replaced the drop bars for Albatross=style bars. It was good equipment that was eventually overtaken by that up-and-coming brand, Shimano.

  2. MT--You and I are probably close to the same age. I, too, came along just in time for the ten-speed craze, and to find out how much better SunTour derailleurs were than just about any other--certainly, they were better than the derailleurs that came on our Schwinns, Peugeots, Motobecanes, Raleighs, Atalas and other bikes of that time.

  3. My wife's Sprite still sports the original Huret front derailleur and the lovely Huret stem-mounted shifters. When I overhauled the bike about 8 years ago, I swapped out the original 27-inch steel wheels for a set of pre-built 700c wheels from Harris Cyclery. These days the Sprite rolls on Panarace Paselas and Sun CR18 rims laced to affordable Quando hubs. It received a new 5-speed freewheel and chain and new brake levers. Those original Raleigh self-adjusting brake levers were shot. It's a lovely machine.

  4. MT--I also think those Huret stem-mounted shifters (and a similar downtube version) are lovely. One thing you have to say for some of the Huret (and other old French) stuff: It had heart and style--especially the Jubilee derailleur and Stronglight cranksets.
