Cute design. For those who haven't seen one, the LaPree rear changer has
three pulleys. Sort of like a six-toed kitten. It's roughly VX quality as I
recall.
Like so much friction equipment, it works fine for what it is - mid range
stuff from a simpler age. If or when it fails you can substitue just about
any rear of suitable length such as the inexpensive SunRace.
I wouldn't judge a bike either way based on that part. What kind of frame is
it? Are the wheels in good shape? Does it fit?

Coo! Anyone got a picture of one of these? I'm intrigued!

I looked through my Suntour file but couldn't find one. Roughly 1982? 1983?
1984? Anyone got it?

is similar to the LePree 3-pulley derailleur
This is from the Suntour Museum:

a six-toed kitten or a three-pulley derailleur?
for the former, look for a pic of dubya's pal ernie...

Nice page, definitely a bookmark.
I keep a SR Maxima from about 84 around because it has a complete Superbe
gruppo including those great pedals. I love the bearings in the hubs.
On the components themselves, they are labeled Superbe but on this web page
they are identified as Superbe Pro.
Several are missing, the crank, which appears to be a Campy SR copy and the
hubs.
I would also like to have seen a picture of my favorite hubs, the Superbe Pro
track hubs, IMHO these are the finest looking hubs ever made and condier myself
fortunate to own a pair for my track bike.
Nice page...

What a wacky idea. Any ideas what the thinking was? I'm not sure what
benefit having three jockey wheels on a mech would be.
Andy Chequer
It increases the takeup capacity of the derailleur. When you are in
combinations which need the most wrap (such as small/small) the third
jockey wheel becomes engaged and takes up some extra capacity.
The alternative method is to use a longer cage rear derailleur. That makes
the derailleur more prone to damage, especially on small wheeled bicycles
(the modern Shimano XT 42t capacity rear derailleur on my 20" drive wheel
recumbent is only a couple of inches off of the ground).

"Mine goes up to eleven"
-Character in Spinal Tap, describing the new numbers on his ten-place
potentiometer.
It allows a "short cage" derailleur to wrap more chain, allowing one
to run a compact rear cog set with a wide-range front crankset.
As others have said, it only appeared for a couple years in the
mid-'80's, roughly when Suntour was on a downward slide and Shimano
was growing by leaps.

There was a 3 pulley Huret Duopar as well.

It is handy, because then you can go one louder.
BIG BOTTOM bracket, anyone?

That makes loads of sense. I get it. So when the mech is swung forwards, the
middle jockey wheel disengages and it behaves like a short cage mech. Having
ones cake and eating it, as it were.
I always lusted after a Suntour XC Pro gruppo for my MTB years ago, was
upset when they went under. Little greaseports everywhere. Now they seem to
make cheapo suspension forks and cranks for the OEM market. Shame.

Yeah, Suntour stuff was really nice, but at the time it didn't shift as
reliably as Shimano, especially the Microdrive stuff. Other than that, it
was of nicer quality.
Going back before that, I think Suntour made the best road stuff by far, for
a long time, until STI came out. Old Campy stuff is prized by collectors.
It looks neat, but functionally it's crap compared to old Suntour. Not too
long ago I had a Cyclone equipped bike that made me feel like an idiot for
riding Campy SR back when it was "the thing." I still wouldn't mind an old
Suntour bike with a freewheel, but I wouldn't touch the cassette stuff now,
for fear of running out of replacement parts.

Completely different company. Similar to Alan Goldsmith's re-use of the
expired names Motobecane and Weyless. Or if you ever saw a Maserati bicycle
in the '70s. . .
