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.
