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.
I’ve responded to a request from a reader for more information about quick-release skewer lengths by going further, with a major expansion of the article about quick releases. The article now covers wheel installation, secondary retention devices including the much-derided “lawyer lips”, and much more. — http://sheldonbrown.com/skewers.html — John Allen, for sheldonbrown.com
The list of Sturmey-Archer indicator spindles now sorts either on the part number or on the spindle length, with a mouse click.
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!
New article on spoke patterns which avoid excessive spoke angles
with large hubs such as electrically-assisted bike hub motors.
New page on how to measure a hub and rim to get the numbers to enter into a spoke-length calculator.
Major revision of the page on rim sizing to determine what tires will fit
Our article about the SRAM G8 hub now also covers the new G9 9-speed.
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.
