A history of Campagnolo from 1901 to 1987.
August 26th, Gentullio (Tullio) Campagnolo is born to Valentino Campagnolo and Elisa Paiusco in Vicenza.
Tullio Campagnolo begins his amateur racing career (with Veloce Club Vicenza on a Cicli Aliprandi) that lasts until 1930.
November 11th, Tullio Campagnolo's frozen hands can't loosen the wingnuts of his wheel to flip it over to a different sprocket during the Gran Premio della Vittoria race across snowy Croce d'Aune Pass (he finishes fourth). "Bisogna cambià qualcossa de drio."... "Something needs to be changed in the rear." He vows to invent a product that will eliminate this problem: the creation of galletti automatici... automated wingnuts or, as we now know it, the quick release.
February 8th, the quick release hub is patented, the first of more than 135 patents for Tullio Campagnolo.
After fabricating parts in the backroom of his father's hardware store (Corsa Padova 101, Vincenza), Tullio starts Campagnolo, S.r.l. with the production of the quick release hub. The sliding hub, dual seatstay rod operated, back pedal derailleur (cambio prototype) is patented on May 4th and introduced in August. The pieces of the prototype derailleur are all handmade requiring a massive investment of time and labor. Fratelli Brivio of Brescia (F.B.) becomes the subcontractor for the parts and supplier of the three-piece (steel barrel with aluminum flanges) hubs. Later, the official corporate name becomes Campagnolo Brevetti Internazionali SpA (translation: Campagnolo International Patents Incorporated).
Cambio a bacchetta (translation: rod changer) or Cambio "CAMPAGNOLO" is the name used for sliding hub, dual seatstay rod operated, back pedal derailleur. The slogan becomes "Senza attriti e senza rumore" (i.e., Friction-free and noise-free). The first advertisement for the Cambio "CAMPAGNOLO" appears in Gazzetta dello Sport.
Tullio Campagnolo hires his first fulltime employee, Enrico Piccolo.
A single page flyer is printed.
The first official Campagnolo logo: the winged wheel highlighting the quick release, a component that remains today the universal standard.
The Cambio Corsa (translation: race changer) is the new name for sliding hub, dual seatstay rod operated, back pedal derailleur; later referred to in Italian as the due leve (translation: two lever) when the una leve (translation: single lever) race changer is introduced in 1949. Two versions of the Cambio Corsa derailleur are available: the short lever Corsa and the long lever Sport. The quick release nut is the original rounded screw head version. On January 12, the Campagnolo winged wheel with quick release logo with the words "Cambio Campagnolo" is registered.
The beginning of the export of parts. Photo of company excursion (company picnic?) pictures 37 employees.
Campagnolo's first foreign plant (assembling and finishing) is built in Cognin, France; the quick release lever is stamped "Brevet France.". The company logo, the winged wheel, is modified with the dropping of "cambio" (translation: changer) and redesigning the wing and quick-release.
Gino Bartali wins the 1948 Tour de France in July using a Cambio Corsa derailleur.
The Tipo Paris-Roubaix sliding hub, single seatstay rod operated, back pedal derailleur is introduced; originally referred to in Italian as the "una leva" (translation: single lever) until renamed in honor of Coppi's April 1950 Paris-Roubaix victory. The quick release nut is now the oval-ring version. The Gran Sport twin cable, parallelogram rear derailleur prototype is shown at the Milan Show in the Fall; it is believed that ten prototypes were made.
Campagnolo employs 123 workers. The Gran Sport single cable, parallelogram rear derailleur prototype is shown at the Fall trade shows.
Fausto Coppi wins Paris-Roubaix in April using the Paris-Roubaix derailleur.
The Gran Sport single cable, parallelogram rear derailleur (chromed bronze, large chromed mounting bolt and pivot bolt and holes in pulleys, set screw-style cable clamp, and "B" adjusting screw for changing derailleur mounting angle that is eliminated by the next year) paired with bar-end shift levers (chromed bronze, then aluminum) without rubber covers and Gran Sport sliding rod, cable operated front derailleur are introduced, along with conventional small flange three-piece hubs (alloy flanges pressed onto a steel barrel and D-ring type quick release nuts). A forged dropout with integral Gran Sport derailleur hanger is introduced that measures 6mm thick with 4mm adjusting screw and derailleur stop at 4 o'clock; easily identified by bulge formed around adjusting screw. Later the same year a new forged dropout is introduced that measures 7mm thick with 4mm adjusting screw and derailleur stop at 7 o'clock (no Sport derailleur spring hole).
Hugo Koblet wins the 1951 Tour de France in July using Gran Sport derailleurs paired with Gran Sport bar-end shifters. Fausto Coppi and Gino Bartali also racing with same set up (only six Gran Sport derailleurs available for their TdF debut).

At the year-end Milan trade show a micro-adjust, two-bolt seat post (steel post and head brazed together) with a zero offset head is shown. Since it has the ears at the front and back of the post let's call it the Alfred E. Newman seat post. Within a few months it is replaced with the iconic two-bolt seat post (separate steel post and head brazed together) with the offset head.
The iconic Record 5-pin cotterless crankset is introduced; 151mm bolt circle, 44 tooth minimum chainring, pedal hole dust caps, relieved spider and raised pedal lip. The Gran Sport pedal is introduced; steel quill with strap loop and small triangular cutout in end of quill, 10mm length thread for steel cranks and rubber "O" ring. In July a headset and a micro-adjust, two bolt seat post (steel post and head brazed together), along with a seat positioning/leveling tool (maintains saddle position when changing seat post) are introduced, followed in August by the Gran Sport rear derailleur with the lower body and outer cage revised (elimination of three of original six spring tension adjustment holes) and an 8mm spring cover (was 5mm).
Gran Sport pedal triangular cutout in quill end eliminated.
The Gran Sport "con denti" (with teeth) track pedal is introduced; aluminum cage plates, 10mm length thread for steel cranks and rubber "O" ring. Also introduced are the Record one-piece alloy, small and large flange hubs (oval holes in flanges, oil hole clip and open "C" on quick release lever) and the seat post introduced in 1956 now has a narrow cradle version to work with the Brooks B17 "Mod. Campagnolo" narrow-railed saddle that has twice the range of fore and aft adjustability. A patent is granted on hollow chainring bolts with Allen key hole and crank bolt cover with Allen key hole.
Record crank pedal hole dust cap is eliminated and Gran Sport road and track pedal thread length changed to 12mm for aluminum cranks from 10mm for steel cranks, rubber "O" ring replaced with rifling on spindle.
A period of great expansion for Campagnolo! Campagnolo employs 300 workers. Inventing and patenting car and motorcycle hydraulic and cable operated disc brake components is undertaken. The Record parallelogram front derailleur is introduced (arms are chrome-plated bronze; later changed to aluminum). Around this time the Gran Sport rear derailleur has its cable tension adjustment screw eliminated and the pulley cage stop screw is countersunk into the lower body. The relieved spider of the Record crank is eliminated. Low-cost steel pedal (rebranded Way-Assauto mod. Zenith Corsa 18 Extra Lusso).
Catalog #14. Printed for the year-end trade shows. Included are the Record road and track groups comprising Record cotterless crankset (151mm bolt circle) and Gran Sport bottom bracket, small and large flange Record alloy one-piece hubs, seat post (now all alloy), Gran Sport headset, Record front derailleur, Gran Sport rear derailleur, Gran Sport pedals. Also in the catalog are the Gran Sport Group (includes Record front derailleur), Sport Group, Gran Sport cottered bottom bracket (note that there is no accompanying cottered crankset), Gran Sport track pedal with and without teeth, wood-boxed tool set, the Saddle-Line alignment tool and the Acciaio (steel) small flange hubs.
Strada triple and Cyclocross cranksets, Sportman low-cost rear derailleur and Sportman medium flange hub with round holes are introduced. In July a revised Gran Sport rear derailleur is introduced with a 10mm spring cover (was 8mm) to improve shifting on six-speed freewheels. Note that six-speed freewheels are not commonplace until the mid-1970s! Campagnolo opens a factory in Bologna to manufacture superlight magnesium wheels for autos and motorcycles, as well as lightweight military and aerospace parts. Campagnolo becomes the first company in the world to use low-pressure magnesium casting, revolutionizing the use of this material.
The Turismo low-cost rear derailleur is introduced; identical to the earlier Gran Sport rear derailleur, but with a cheaper stamped-steel pulley cage substituted for the original cast-steel pulley cage. The raised-lip around the pedal hole of the Record crank is eliminated.
110 out of 130 cyclists in the 1963 Tour de France are equipped with a Campagnolo derailleur.
In October the Record rear derailleur (chrome plated bronze) is introduced. This has a revised cage shape with the pivot behind and closer to the jockey pulley and center punched rivets; it is designed to be able to shift the new six-speed Regina freewheel and back of body is marked "13-36" for usable freewheel size (in reality, a 13-28 freewheel is the maximum). Note that six-speed freewheels don't come into common usage till the mid-late seventies. Record bottom bracket marked "CON SFERE DA 3/16" using 3/16" balls instead of typical 1/4" balls. The races are pressed onto the spindle rather than machined directly on the spindle itself. Neither the cups nor spindle are interchangeable with bottom bracket components designed for 1/4" balls. Made for one year. A new wider base clamp design for the cable guides and down tube shifters along with thicker down tube shift levers with open "C" changed to closed "C". The word "Record" is added to the hub barrels and open "C" on quick release lever changed to closed "C". Thicker heads on seat post adjusting bolts. Next generation Record headset with non-domed lock nut, plain keyed washer. The low-cost "CAMPAGNOLO" model derailleur, an economy version of the Gran Sport derailleur (cadmium plate body and black oxide finish on pulley cage with the word "CAMPAGNOLO" on body), and also the low-cost Sportman rear derailleur are introduced. Record front derailleur has slot added to cable stop.
The Valentino low-cost rear derailleur is introduced along with the Valentino low-cost front derailleur and obscure large flange track hubs with curved lever quick releases. Curved QR lever first appears eleven years earlier as Daniel Rebour drawing in an issue of Le Cycle magazine dated 25th of July, 1953!
The Record rear derailleur (chrome plated bronze) has the no-teeth steel pulleys with ball-bearings replaced with plastic pulleys with ten teeth and plain bronze sleeve bearings.
The Record crankset is changed to a 144mm bolt circle (41 tooth minimum chainring) from the previous 151mm bolt circle (44 tooth minimum chainring); initially referred to as the "Special Record" crankset and doesn't appear in Catalog #15. The Sport low-cost hubset (large and small flange all steel hub) is introduced in January. Patent granted for self-centering wine bottle opener in the shape of a bell (lever pivots are the patented hollow chainring bolts).

Record front derailleur clamp modified in area of pivot posts; first with no circlip on upper pivot post and later with circlip added to upper pivot post. Special Nuovo Tipo hubs made for Motobecane with oval, kidney-shaped holes instead of the normal round holes; used as original equipment on the 1972/3 Motobecane Le Champion model. Hugo Rickert (Rickert Cycles - Dortmund, W. Germany) orders 300 HiLo hubs (large flange on drive side, small flange on non drive side) to be custom-made by Campagnolo in 1972 and builds the wheels for the West German National Team for the 1972 Munich Olympic Games.
The last year that the Record rear derailleur is available. The large chainring has a tiny post added at the crank arm location so an unshipped chain can't get jammed in the space between the crank and the chainring. The Super Record rear derailleur is introduced.

Introduction of Record Corsa and Record Pista groups at the end of the year trade shows. Usually referred to as "C-Record" (C = Corsa) and not available for sale till around 1986.
Super Record cranks without milled flutes (first produced with engraved logo and later with laser-etched logo) derived from the 1983 Anniversary group cranks and Super Record seat post without milled flutes to match new Super Record cranks.
A seven-speed "compact" spaced freewheel is introduced.
The last year of production of Super Record components. A final short production run of Record hubs is made utilizing surplus parts. Also some C-Record front hubs are made utilizing surplus Record front hub 7/32" bearings, cones and races. Normally C-Record front hubs use 3/16" bearings and both Record and C-Record rear hubs use 1/4" bearings. Both the Record and C-Record hubs are marked "S - U" on the hub barrel.
Typically the development of Campagnolo parts was carried out with the help of professional road and track riders on teams sponsored by Campagnolo. Consequently, Campagnolo parts were in use one or more years before they were ever offered for sale to the public. Campagnolo parts could appear in stores or on bikes before ever appearing in a catalog or, on the other hand, were not necessarily available at the time a catalog was issued. The catalogs were typically printed for the trade shows which occurred late in the year (the Milan bicycle trade show was held biannually, odd numbered years). For these reasons, all dates in the Timeline are approximate.
Some Campagnolo parts can be dated by codes or patent dates. For example, the Nuovo Record rear derailleur has a patent date that corresponds to its manufacturing date starting in 1970 (example "PAT. 70"); marked "PATENT" without a date before 1970. The lock nut on the hub axle typically is stamped with "CAM. 60" or some other number denoting the last two digits of the year of manufacture. The word "RECORD" was added to the hub barrels around 1963. The original "Open C" style Campagnolo logotype (imagine a U turned on its side) on the Q.R. levers was changed to a "closed C" in 1958 with the introduction of the one-piece alloy Record hubs and a little later to the shift levers. Starting in 1973 the crank arms have a code consisting of a diamond (1970's) or circle (1980's) with a number in the center denoting the last digit of the year of manufacture, and then in 1985-9 with square and number in the center: 11 = 1985, 21 = 1986, 31 = 1987, 41 = 1988, 51 = 1989 plus some other examples.
The original Campagnolo Timeline first appeared in a 1995 series of articles in the AEoleus Butterfly 'zine printed by Gabe Konrad. The original contributors were Gabe Konrad, Frank Berto, Ron Sheperd, Dale Brown, and Chuck Schmidt. In 1998 it was taken over by Chuck Schmidt and added to the Velo-Retro website. Since then, many people have made contributions to the Timeline: Hilary Stone, Peter Johnson, Richard Sachs, Dave Walker, John Barron, Dan Ulwelling, Tom Dalton, Hiroshi Ichikawa, Satoru Masada, Dr. Akihiko Amaki, Steven Maasland, Jan Heine, Marc Borel and Ted Ernst among others.
I would greatly appreciate any assistance you the reader can offer in updating this timeline as this is the only way the accuracy of this timeline can be improved. Chuck Schmidt
