Our Sturmey-Archer 4, 5 and 7-speed hub page has been updated with links to newly-available information on recent 5-speed hubs.
Update to 5-speed hub information
Tag: internal-gear
Shimano Alfine 11-speed hub
New article about the Shimano Alfine 11-speed hub. Thanks to Bruce Dance for most of the text, also Aaron Goss!
SRAM Automatix 2-speed hub
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.
Gear Calculator updated and now also in German
The Sheldon Brown gear calculator is updated and improved: more tire sizes are covered including fatbikes, 29ers, 29+ and monster bikes, and we now have a version in German, as well as French.
Additions to the Shimano 8-speed IG hub page
Sheldonbrown.com reader Bruce Dance has contributed some helpful information on compatibility — or the lack of it — among different models. Read it on the 8-speed internal-gear hub page
.
Additions to the Gear Calculator
New crank lengths have been added to the Gear Calculator and Internal Gear Calculator, so they can calculate gain ratios for children’s bicycles with cranks down to 100 mm (less than 4 inches).
More hubs in cable-pull cribsheet
Added information on four hubs to the internal-gear hub cable pull cribsheet:
Shimano Alfine 11-speed
SRAM G9
Sturmey-Archer S3X
Sturmey-Archer ASC
Thanks to Jeff Meredith and Michael Wilson for the measurements!
Shimano 4-speed hub gears
Expanded coverage of Shimano Nexus 4-speed hub gears — we now have rebuilding information, translated from manuals in German which are the only ones we could find online — complete instructions for both the freewheeling/Rollerbrake version and the coaster brake version. Thanks go to Patricia Morris for assistance with translation.
New tire sizes in Gear Calculator
Several tire sizes have been added to the Gear Calculator:
Fatbike sizes: 26 inch tires, 26 x 3.8, 4.0, 4.25, 4.7
Wide 29ers: 29 x 2.7 and 3.0
32 inch and 36 inch (common on unicycles).
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.
