Sachs was a European conglomerate that bought up many of the formerly independent French parts makers, including Atom/Maillard/Normandy (hubs, pedals, freewheels) Huret (derailers) and Sedis (chains.) Sachs also made multi-speed internal-gear hubs in 3-, 5-, 7- and 12-speed versions.Their "3 x 7" hub was a hybrid system, a 3-speed internal hub that took a 7-sprocket cassette, providing 21 speeds with only one chainwheel.A major contribution was to discard the idea that a tandem should be as much like a solo bike as possible, with a short wheelbase for good handling.By increasing the room for the stoker, Santana made the tandem much more pleasant to ride. There is a third type of valve, very rarely seen in the U.If the threads do not extend full length, technically it is a "bolt" but only pedants insist on this distinction.

The bicycle division was sold to the SRAM Corporation, in November 1997.
Most of the products formerly called "Sachs" are now called "SRAM." Up-to-date information is on the SRAM site.
Before Santana came onto the scene, there had been low-quality nass-produced American tandems, mediocre mass-produced French ones and a few high-grade custom ones from English and European makers.
Santana undertook a major rethinking of tandem design.
