Major update to our page on Shimano and Shimano-compatible 9-speed cassettes. We’ve fixed broken links from when manufacturers updated *their* Web pages, and updated information on availability.
New article about the SRAM Automatix two-speed hub. We have information on maintenance, choice among variant models, and how to adjust the speed at which it shifts automatically.
Added information on four hubs to the internal-gear hub cable pull cribsheet:
Shimano Alfine 11-speed
SRAM G9
Sturmey-Archer S3X
Sturmey-Archer ASC
Thanks to Jeff Meredith and Michael Wilson for the measurements!
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.
NEW – Crib sheet of internal-gear hub shifter cable pull measurements
The main thing this shows is that there is very little compatibility, though there is *some* — mostly among three-speeds, though not always among them either. I thank Alex Wetmore and Jeff Bertolet for help with this page.
John has added some owner comments to the page on SRAM G8 and G9 internal-gear hubs. Opinions are generally very positive.
The cable travel adapter cribsheet has been edited to include more information, and links.
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!
New section on how the SRAM i-Motion 9 hub works in the article about that hub.
