Every once in a while we go back and review our pages to deal with product changes and link rot. We just did that with all our pages about Sachs and SRAM internal-gear hubs. You will find product manuals here which are hard to find anywhere else. You can start with our main page about these hubs.
We have updated all of our pages about Sachs and SRAM internal-gear hubs, fixing broken links and, regretfully, indicating that SRAM is now no longer making internal-gear hubs. But many of you are using these hubs, and we are maintaining information on them. Main page with links to others.
Updates to our main page on Sachs and SRAM hubs , and our page on the G8 and G9 hubs. We have located additional technical information from SRAM, and wehave fixed a number of Web links that went bad.
John has added some owner comments to the page on SRAM G8 and G9 internal-gear hubs. Opinions are generally very positive.
Our article about the SRAM G8 hub now also covers the new G9 9-speed.
New article about the SRAM G8 8-speed internal hub gear 
— all you need to know to install this hub: specifications, gear ratios, parts compatibility and availability, how the mechanism works. As far as we know, this is the one place on the Web where you can find all this information. And if you happen to read German, we have an absolutely terrible pun for you too. Achtung, indeed!
There’s more troubleshooting advice now in our article about Sachs/SRAM internal-gear hubs: how to test whether a problem is inside the hub, or only in the shifter and cable — for hubs with 3, 5 or 7 speeds, with pullchain(s) or clickbox.
