What's new at sheldonbrown.com
Our Shimano 7-speed hub page is now updated to fix the links which broke when Shimano redid its Web site. We have also added information about new models, and made a few improvements in the text. All of our pages about Shimano internal-gear hubs are now up to date.
Shimano Nexus 4-speed page updated — in our continuing quest to keep up to date with Shimano’s ever-changing Web site, we’ve updated the links and related information on Shimano Nexus 4-speed internal-gear hubs
Sheldonbrown.com provides a forwarding page whenever we consolidate or move material. Not so Shimano, which broke all our links to its technical information. Sigh. We have just repaired our page on Shimano 8-speed internal-gear hubs.

The Shimano 3-speed hub page has been updated with coverage of the SG-3R75 pulley-shifting hub including drive ratios. The gear calculator pages also have been updated.
Our page about Shimano 8-speed internal-gear hubs now includes information on the new hub models. The table listing hubs has a new column indicating which cassette joint or motor unit works with each hub, and which hubs have interchangeable internal parts.
Sheldonbrown.com reader Bruce Dance has contributed some helpful information on compatibility — or the lack of it — among different models. Read it on the 8-speed internal-gear hub page

Major revision to the page about Shimano 8-speed hubs:
— Added information on new hub models and fixed the many links which Shimano broke when it went to its new organization of technical Web pages.
— Linked to a number of documents Shimano abandoned. They’re available in the Internet Archive.
— Located other orphaned information where I could find it elsewhere on the Internet.
All in all, I’ve brought the information on each model of hub together in one place, to the degree possible with what I could find. Please let me know about errors and omissions.

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.
