Shimano Alfine 11-speed page update

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

Shimano 3-speed hubs

We have updated our page about Shimano 3-speed hubs. Shimano redid its Web site and broke all the links to technical information. We have repaired the damage and added a few more links, tips and tricks as well.

Unthreaded bottom-bracket update

Major update to the unthreaded bottom bracket cribsheet: several additional ones covered, broken links repaired. yes, everything from Ashtabula one-piece crank BBs (as shown in the photo) to the Klein Team Super to eccentrics for tandems.

New coverage of Shimano 3-speed

The Shimano 3-speed hub page has been updated with coverage of the SG-3R75 pulley-shifting hub including drive ratios. The gear calculator pages also have been updated.

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.

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!

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.
