New article, derailerless drivetrains
: How to choose frame and rear hub for a happy combination on a bicycle without derailers: a fixed gear, singlespeed, internal-gear hub, coaster brake bicycle — and how to adjust the chain tension. This article compiles information from the articles on fixed-gear and singlespeed bicycles. but adds to it and puts it in one place. Most issues with all derailerless drivetrains are the same, but there are important differences to note, there is new equipment to cover, and there are additional techniques to describe.

SRAM and Sachs Internal-gear hubs
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.
Sturmey-Archer Pages Updated
Major update to the Sturmey-Archer pages:
* fixed links which S-A broke by redoing its Web site (that’s everything about current hubs).
* updated the list of hubs.
* Added new technical information.
Our cribsheet of hub model names and descriptions is a good place to start.
Crib sheet of internal-gear hub cable-pull measurements
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.
Click to re-order spindle list
The list of Sturmey-Archer indicator spindles now sorts either on the part number or on the spindle length, with a mouse click.
More indicator spindles
David Prosser of Sturmey Archer has sent information about a couple of Sturmey-Archer indicator spindles (the chain-pull assembly which shifts the hub). It is now on our indicator spindle page. Thanks David!
Wandering the show floor at the Interbike trade show
It took a few days to finish — the big page about products of interest seen on the show floor at the Interbike trade show.
SRAM G9 Hub
Our article about the SRAM G8 hub now also covers the new G9 9-speed.
Home-brew hybrid gearing
Additions to the article on internal-gear hubs — more about how to construct a multi-speed hybrid-gearing system using a stock 3-speed hub and two sprockets and/or two chainwheels. It indexes even without index shifters! Photo courtesy of Mark Stonich.
