Shimano 8-speed Internal-Gear Hubs
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.

The cable travel adapter cribsheet has been edited to include more information, and links.
Bottom bracket information revised
We’ve added David Richardson’s photo of damage to a Shimano Octalink V1 crank from installing it on a V2 spindle to the bottom-bracket database. Also, we’ve coordinated bottom-bracket threading standards tables in the several files where they appear.

New cribsheet page with dimensions of unthreaded bottom brackets, and compatibility information.

Biopace chainrings
We like Shimano Biopace non-round chainrings, and they are reliably available on eBay. We have expanded our article on how to choose and use them.
Shimano Nexus 4-speed
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…
