The Sachs Elan was a epicyclic internal hub gear for bicycles, introduced by the bicycle division of the German company Fichtel & Sachs in 1995 and manufactured until 1998. With its 12 speeds and an overall range of 339%[1] it was the most advanced epicyclic hub gear at the time, and the first hub gear commercially available with more than 7 speeds. However, the Elan was perceived as unreliable and heavy.
After SRAM Corporation took over ownership of the German bicycle component manufacturer, the Elan was sold under the name Spectro E12.[2][1]
The Elan recieved a blow with the introduction of the Speedhub 500/14 by the small family owned company Rohloff AG, a technically more advanced product, and was discontinued before the turn of the millennium.
Specifications
Weight was a full 3.4 kg (7 1/2 pounds) and 4 kg with an integrated coaster brake.[2]
