The exact year Peugeot introduced their legendary PX-10 model is subject to debate
in the cycling community.  While they clearly introduced a PHX-10 in 1953 and a
PLX-10 in 1956 some dont consider those to be true PX-10's due to the extra
lettering and lack of Reynolds tubing.  PX-10's without prefixes and/or suffixes
appeared as early as 1961.  Considering Peugeot changed the designation
depending on options it only makes sense to include models as early as 1953.  
Would it be fair to exclude 1974's PX10LE from being a true PX10?  Of course not,
therefore its not fair to exclude any other model or year.  It is the opinion of the
author that PX-10's first appeared in 1953 and continued through at least 1990
appearing as the 'Dolomites' model paying homage to an Italian mountain range.  
There is also debate as to whether Peugeot PX-10's without Reynolds tubing are
true PX-10's.  Throughout the years regardless of nomenclature, Peugeot used a
variety of tubing, Vitus, Reynolds, Columbus and a variety of materials as such as
high carbon steel, chromoly, aluminum and carbon fiber while constructing their top
of the line bikes,

A brief history
1898  Top of the line racer listed as 'course route'  which translates to 'road race' with a price of 400 francs.
1902 "Lion" course route single speed with standard front brake, narrow crankset and wooden rims.  400 francs
1903 Bicyclette A, type course 11.5 kgs 285 francs
1912 Trophee de France, Brooks BN17 saddle, flip flop rear hub 14 francs
1914 Bicyclette E Route, pump and tool kit standard.  240 francs
1925 'Tour de France' standard front and rear brakes, pump and tool kit.
1927 P10 designation appears.  Front and rear brakes, tool kit, Dunlop tires and wooden rims standard.  700
1930 P10 wooden rims with front and rear cable operated brakes, tool kit and pump.
1932 P0  Created specificaly for sportsman and professionals.  790 francs, Brooks saddle 35 francs
1933 PC10 'C' designates 'course' or 'race'.  This is the first year in which Peugeot surronds '10'  with 1951
PH10 Vitus tubing, Simplex front and rear gear changers, Stronglight headset and cranks, 4 speed freewheel,
stainless steel spokes.  Color: red vermillion
1953 The 'X' factor: A new beginning.  1953 ushered in a new era for Peugeot with the introduction of the 'X'
models.  An 'X' in any model name signifies construction with 'inoxydable' or 'stainless' tubing.  The tubing itself
wasn't stainless steel but treated to prevent rust or staining of the metal.  In 1953 Peugeit gauranteed thier
stainless series or 'series inox' not to oxidize for 2 years!!!
1958 Reynolds tubing appears for the first time on the LX10 model.  For some unknown reason Peugeot didnt
label their line with 'P' designations for 1958.  It is possible the catalogs were printed with a typo but they could
have done it intentionaly.
1974 Peugeot begins offering custom made bicycles with the 'PY' designation
1980 CFX10 frameset debuts
1983 PY10FC debuts constructed with carbon fiber and Vitus forks.
1984 PX10's constructed with Vitus Duralinox 979 frame and forks.
1986 PZ10 debuts with Reynolds 531 tubing.  PX10 constructed with Colombus SLX tubing.
1989 Second generation carbon frame debuts.  Built in conjunction with Zodiac.

PX-10  1953-1990  Occasionaly not listed in catalogs.
Peugeot has always offered off the shelf bikes to their customers that were very similar to what their
proffesional teams rode.  Its a concept that all big companies follow.  An individual can go into the nearest
footwear store and buy a pair of Air Jordans so they can wear what Michael Jordan wears or you can buy a
baseball bat and swing what Ken Griffey Jr. or Miguel Cabrerra swings.  Fans of sport want to use the same
equiptment as their sports heroes whether it be a baseball bat or a bike.  Peugeots PX-10 allowed their
customers to ride what 1965 road race world champion Tom Simpson, 1966 road race world champion Eddy
Merkx,  and 2 time Tour de France winner Bernard Thevent rode.  I believe Peugeots popularity arose due to
two reasons.  First, they won.  No one wants to be associated with a loser.  If Spyker won the Formula 1 world
championship they'd sell all the cars they could versus filling for bankruptcy.  To prove my point, ask yourself,
who's Spyker?  Second, during the peak of the '70's bike boom Peugeot won the Tour de France
twice.  What
better way to sell a bike than to be able to say, "this bike just won the Tour de France", Peugeot could almost
could gaurantee high sales volume.  With the introduction of PY and PZ models the PX would no longer be
Peugeots top of the line of the shelf bike.

PY-10  1975-1980 in U.S. Available in Europe through 1986.
In 1974 Peugeot opened their prestige frame shop which specialized in the production of custom specification
Reynolds tubed framesets.  These custom frames were called PY-10's.  Similar to a PX-10 in design and styling,
a PY-10 could be ordered to a customers personal specifications.  Options included, but were not limited to,  
custom geometry, color, components and braze on options.  PY-10's were primarily built with thin gauge, butted
Reynolds tubing.  The French market was fortunate in that they were able to buy PY's off the shelf as well as
custom ordering them.  The U.S. market wasn't so fortunate.  In later years Peugeots race team switched to
carbon fiber tubed bikes which were refered to as the PY10FC.  During this time Peugeot continued to offer a
custom order steel bicycle, the PZ10

PRO-10 1982 only in U.S. Available through 1986 in Europe.
Essentialy a PY-10.  Available in the U.S. for 1982 only and characterized by a fully chromed rear triangle and
fully chromed fork.

PY10-FC  1983-1988
Three tube carbon fiber frame with Vitus duralinox aluminum lugs, rear triangle and fork.  Although not
mentioned in the literature, more than likely produced by Vitus in conjunction with Peugeot  

PX-10DU  1984-1985 European.  Not imported to U.S.
Constructed with Vitus Duralinox aluminum frame and fork.  Used by Peugeots team in the Tour de France

PZ-10  1983-1987
PZ-10 production began in 1983, coinciding with production of the carbon fiber PY10FC.  PX-10 production
continued with the PZ becoming Peugeots new custom order steel bicycle.  PZ and PY production continued in
the U.S. market until Peugeos withdrawal from the U.S. in 1990.
