Oscar Egg

Oscar Egg (2 March 1890 – 9 February 1961) was a Swiss track and road bicycle racer. He captured the world hour record three times before the First World War and won major road races and stages of the Tour de France and Giro d'Italia. He was also a noted developer of racing bicycles and bicycle components including lugs and derailleurs.

The hour record Between 1907 and 1914 Oscar Egg and Marcel Berthet improved the hour record six times between them. Egg's 1914 mark of 44.247 km then stood until 1933. Egg set all three of his records at the Vélodrome Buffalo in Paris. The track was a 333m outdoor track surfaced with concrete. The sequence was as follows: 20 Jun 1907, Marcel Berthet, Paris, 41.520 km 22 Aug 1912, Oscar Egg, Paris, 42.122 km 7 Aug 1913, Marcel Berthet, Paris, 42.741 km 21 Aug 1913, Oscar Egg, Paris, 43.525 km 20 Sep 1913, Marcel Berthet, Paris, 43.775 km 18 Aug 1914, Oscar Egg, Paris, 44.247 km

Only Chris Boardman has equaled Egg and Berthet's feat of taking the record three times. The last record, set by Egg in 1914, would stand for nearly 20 years until it was broken in 1933 by Francis Faure on a Mochet velocar. This caused such a reaction that Faure's achievement was disqualified by the Union Cycliste Internationale (UCI) in 1934.

Cycling components

Oscar Egg owned a bicycle shop and workshop in Paris, and began manufacturing racing bicycles and components after he retired from racing. In response to the success of the Vélo-Vélocar in the 1930s, Egg created a streamlined recumbent in an effort to be the first to travel more than 50 kilometers in a single hour, but he was beaten to it by Francis Faure in an actual Vélo-Vélocar.

Derailleurs Egg introduced his first derailleur, called Champion, in 1932. It supported as many as 3 different gear ratios and consisted of two parts: a fork mounted near the rear sprocket for moving the chain and a separate tension arm mounted near the front chainring for taking up slack.

By the 1950s, fork-type derailleurs, such as the Egg Super Champion, were superseded by double pulley designs, and production ceased before 1960.

Lugs Egg developed and marketed lugs for the assembly of steel bicycle frames by brazing. Frames exist with decals advertising the fact that they use "Oscar Egg Super Champion Lugs".
