John has compiled an article with dimensions of most kinds of Sturmey-Archer indicator spindle – the little rod and chain which the shifter cable pulls to shift the gears inside the hub. There are over a dozen different indicator spindles, with different lengths, intended for different hubs — but importantly, there is a lot of compatibilty among them.
John has put together a new article about the Shimano Nexus 4-speed internal-gear hub, with links to a parts list and servicing information. This hub has been discontinued, but in case you want to keep one going…
John has added information to the article about Shimano Nexus and Alfine 8-speed internally-geared hubs, describing common failure modes and how to forestall failure; how to determine whether a hub might need service; and also normal noises and “clunks” which these hubs make, to avoid unnecessary alarm.
We present a collection of images of bicycles and parts that Sheldon felt “some folks might find fun to use as a screensaver”. They might be used for desktop images. The images are all 1024 x 768 pixels, horizontal orientation. Sheldon put a 2008 copyright on this page so it is one of the last things he created before his untimely death on February 4, 2008. Though these images have been available since 2008, we only stumbled across them recently and there were no links to them on the site until now.
New article about the SRAM i-Motion 9 internal-gear hub — the only public source of information on how to rebuild this hub, and with links to installation information and (hard to find!) parts lists from SRAM.
Major additions to the article on Shimano Rollerbrakes — advanced instruction on maintenance, more advice about when these brakes are most suitable.
Shimano has some new internal-gear hubs. We’ve updated the Shimano 3-speed page, and the internal-gear hubs page.
We have spiffed up an article about the Rohloff 14-speed internal-gear hub which had been lurking on the Harris Cyclery part of the site and placed it with the other informational articles.
John has written a new article about torque, as it applies to threaded parts, braking and drivetrains.
