Few photographs exist of Mario Confente. Those that do are in black and white and coarse throughout. Viewed together they offer a blurry, unstaged portrayal of a man attending to the mundane details of his life’s work. They serve as proof positive that labor is at the root of all art, and that, as an artist, Confente toiled in relative obscurity.

Confente was a master builder of bicycle frames. The backbone of a bicycle is its frame, upon which wheels and all other components are mounted. Nothing is more vital in determining the ride quality of a bike—its smoothness or stiffness, its springiness or rigidity. Bicycle frame making is a craft equaled perhaps only by the handmade production of musical instruments or firearms in the way in which aesthetic detail directly impacts the performance of what is, in essence, a functional object.

Confente trained under the legendary Faliero Masi in their native Italy during the early 1970s. Today Masi remains a patriarch of the modern road-racing frame and has the distinction of being the personal frame builder of the greatest bicycle racer in the history of the sport, Belgium’s Eddy Merckx. Confente showed such skill at the torch that Masi chose him to head his new American facility in Carlsbad, Calif., in 1973. Confente built Masi frames there for a few short years before the American operation slowed down. He then seized the opportunity to fulfill his lifelong dream of building frames with the Confente marque, and opened his own workshop in Los Angeles.

Confente made his public debut at the 1977 New York City International Bike Show, where his frames stopped cycling purists in their tracks. His bikes represented a masterful combination of two schools of obsession: the Italian fixation with style and artifice, and the puritanical American mania for manufacturing processes and structural integrity. Confente historian Russell Howe interviewed America’s premier frame builders for the Classic Rendezvous website (www.classicrendezvous.com) about that now legendary show, and their impressions are remarkably consistent.
