Oscar Egg

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.

[2] Egg tested an aerodynamic fairing in the form of a tail cone on a bicycle labeled the rocket-bike (vélo-fusée in French) in 1913.

[11] Egg Super Champion derailleurs were marketed in Britain by the Constrictor Tyre and Accessories Company under the name Osgear.

[12] By the 1950s, fork-type derailleurs, such as the Egg Super Champion, were superseded by double pulley designs, and production ceased before 1960.

[14] Other components bearing Egg's name include brakes, cranks, fork crowns, frames, and hubs.
