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.

.
Continuing our updates of Shimano internal-gear hub pages, we have now updated our page about Shimano Alfine 11-speed hubs.

Our page about Raleigh Twenty bicycles has been expanded with two new sections, about the hinge and the rear rack. Find out why the humble and disdained Pletscher rear rack works great on a Twenty, and how to make a replacement for a missing hinge key.

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!
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.

Information has been added to the Creaks, Clicks and Clunks page to help you diagnose several more problems. The page now covers more types of cranks, the noiseless lurches and bumps which occur due to tire damage, chain too wide for the sprockets, worn-out bottom bracket bearings, chain rub on front derailer…
Our Sturmey-Archer 4, 5 and 7-speed hub page has been updated with links to newly-available information on recent 5-speed hubs.

New article about the Shimano Alfine 11-speed hub. Thanks to Bruce Dance for most of the text, also Aaron Goss!

New article about the SRAM Automatix two-speed hub. We have information on maintenance, choice among variant models, and how to adjust the speed at which it shifts automatically.
