The Sachs Elan was an epicyclic internal hub gear for bicycles, developed and manufactured by the bicycle division of the German company Fichtel & Sachs. It was considered heavy and production units were plagued with quality issues. The gear hub was discontinued before the turn of the 2000 millennium.
History
[edit]The Elan was introduced 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.
After SRAM Corporation took over ownership of the German bicycle component manufacturer, the Elan was sold under the name Spectro E12.[1][2]
The Elan received a blow with the introduction of the Speedhub 500/14 by the then small family-owned company Rohloff AG of Hessen, Germany, a technically more advanced product, and was discontinued before the turn of the 2000 millennium.
