What's new at sheldonbrown.com
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.
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.
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
.
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).
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).
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.
Updates to our main page on Sachs and SRAM hubs , and our page on the G8 and G9 hubs. We have located additional technical information from SRAM, and wehave fixed a number of Web links that went bad.
Information the current series of Sturmey-Archer 8-speed hubs has been added to the cribsheet of internal-gear hub cable pull measurements. Not quite the same as for the earlier series! Thanks to David Choma for the measurements!
Major update to the Sturmey-Archer pages:
* fixed links which S-A broke by redoing its Web site (that’s everything about current hubs).
* updated the list of hubs.
* Added new technical information.
Our cribsheet of hub model names and descriptions is a good place to start.
John has added some owner comments to the page on SRAM G8 and G9 internal-gear hubs. Opinions are generally very positive.
