Bridgestone 1982 Catalog
Thanks to Daniel den Hartog for his PDF of the 1982 Bridgestone Bicycles catalog, now online from the Bridgestone table of contents page along with all the other catalogs from 1985 through 1994 and a wealth of other information.
Sachs Elan/SRAM E12 Internals
John has posted a new article about the mechanism of the Sachs Elan/SRAM E12 12-speed internal-gear hub; the largest, heaviest, most complicated internal-gear hub ever marketed — flawed execution of a brilliant design concept. The unusual way this hub establishes its ratios carries an important lesson. In connection with that article, John has updated his article about the history of the Elan, his main page about Sachs/SRAM hubs and the internal-gear calculator.
More about Sachs/SRAM hubs
John has prepared a new page about the Sachs Orbit hybrid-gear hub and added information about this hub to internal-gears.html and sachs-internal.html; also links to Karsten Stielow’s very interesting Web pages about Sachs and SRAM hubs.
