Campagnolo is an Italian manufacturer of bicycle components with headquarters in Vicenza, Italy, one of the most prestigious names in cycling. The components are organised as groupsets (gruppi) and are a near-complete collection of a bicycle's mechanical parts. Campagnolo's highest grade groups are Record (Super Record up to 1985), followed by Chorus.
Founded by Tullio Campagnolo, the company began in 1933 in a small Vicenza workshop. The founder was an bicycle racer in Italy in the 1920s and he conceived several ideas while racing, such as the quick release mechanism for bicycle wheels, derailleurs, and the rod gear for gear changing. Gino Bartali made a strong impression as he won mountainous races while using this gear. Campagnolo has 135 patents. 
At the end of the 1950s Campagnolo started to manufacture magnesium parts such as wheels for sports cars like Alfa Romeo, Ferrari, and Maserati, and also built chassis for NASA satellites in 1969. Campagnolo Milestones
Campagnolo worked closely with the famous racer Eddy Merckx, and produced special lightweight parts for his bike used to beat the world one hour record in 1972.
Despite having lagged in innovations such as indexed gears, and combined brake and gear levers in the 1980s, Campagnolo introduced its Ergopower gears.
The late 1990s and early 2000s saw Campagnolo start using carbon fibre parts in groupsets, and the development of wheelsets. In 2004 Campagnolo introduced a complete Compact drivetrain with smaller chainrings, to enable lower gears than traditional drivetrains. Campagnolo is developing electric shifting.
Campagnolo has focused on road cycling and track cycling. Campagnolo's last foray into mountain-biking was the ill-fated Record-OR groupset. Campagnolo sponsors many teams in the UCI ProTour, such as Caisse d'Epargne, Cofidis, Quick Step-Innergetic (Tom Boonen, Paolo Bettini), and Lampre. Campagnolo is associated with the victories of Eddy Merckx, who used Campagnolo almost exclusively, and was friendly with Tullio Campagnolo.

1987 The last year of Super Record until 2008
1989 Campagnolo introduces its mountain bike groupset, heavier and less advanced than those made by Shimano and SunTour.
1992 Introduction of Ergo Power levers, combining brake lever and a shift lever to answer Shimano's STI levers
1993 Delta brakes discontinued
1994 Campagnolo leaves the mountain bike components business

2004 Carbon-fibre cranks for Record and Chorus groups
2005 10-speed Centaur and Chorus shift and brake levers introduced for flat bar road bikes
2006 Hollow external bearing crankset announced
2007 Introduction of 10-speed Mirage and Xenon component groups, new Ultra-Torque components
2008 Introduction of 11-speed Record, Super-Record and Chorus groups
Fulcrum Wheels, a company owned by Campagnolo, produces wheelsets compatible with Campagnolo and Shimano cassettes.
The ErgoBrain is a cyclocomputer compatible with the Ergo shifters. It displays cadence, gear used, as well as the normal functions of a cyclocomputer.
