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.
Why did this crash happen?
Gear Calculator now supports 12-sprocket cassettes
Update to our gear calculator. It now supports custom 12-sprocket cassettes, and has a listing for the stock SRAM 12-sprocket cassette. Not that we really think that thin sprockets, with a flimsy chain, are a good idea!
More tire sizes
We’re added some bicycle tire sizes (mostly, rare Dutch sizes) to the ISO cross-reference list in our tire-sizing article. We think we have all currently available sizes covered, but if you know of others, please let us know.
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.

More info on SRAM internal-gear hubs
More information on the SRAM S7 internal-gear hub — a reader has sent us links to step-by-step rebuilding information and model comparisons, with photos. The text is in Russian but the photos tell the story and then there’s Google Translate. We’ve also checked an updated all the links on the page.
Sheldon’s journal dusted off
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
