Major update to Shimano 8-speed IG hub page

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.

Updated information on drivetrain compatibility

Our article about cassettes has been updated to include information on 11-speed systems. Interesting — all major brands of 11-speed casettes now have the same sprocket spacing. Most rear derailers and shifters are not compatible, though. We can tell you which ones are.

Sheldon Brown self-portrait, January 9, 2007

Sheldon Brown kept an online journal for several years. He coded it himself in html rather than using blog software. Sheldon reviewed books, movies, concerts and TV programs, as well as describing his travels and other interests including, of course, bicycles and bicycling. Harriet is in the process of dusting off the journal, reformatting it for easier reading, repairing broken links, etc.

Pages which have been redone as of now are those from January and February 2006 through January – February 3, 2008
