Update to the 10-speed cassette page

Major update of the 10-speed cassette page — covers new models and an additional brand.

Shimano 9-speed cassettes

One-ramp sprocket for Shimano Hy0perglide cassette — One-ramp sprocket for Shimano Hyperglide cassette

Two-ramp 15T sprocket for Shimano Hyperglide cassette

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.

SRAM Automatix 2-speed hub

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.

Thanks to Jeff Meredith and Michael Wilson for the measurements!

SRAM and Sachs Internal-gear hubs

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.

Addition to page on SRAM G8 and G9 hubs

John has added some owner comments to the page on SRAM G8 and G9 internal-gear hubs. Opinions are generally very positive.

Edit to cable travel adapter cribsheet

The cable travel adapter cribsheet has been edited to include more information, and links.

SRAM G9 Hub

Our article about the SRAM G8 hub now also covers the new G9 9-speed.

SRAM G8 Hub

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!
