What's new at sheldonbrown.com
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.
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).
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.
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.
The list of Sturmey-Archer indicator spindles now sorts either on the part number or on the spindle length, with a mouse click.
The cable travel adapter cribsheet has been edited to include more information, and links.
It took a few days to finish — the big page about products of interest seen on the show floor at the Interbike trade show.
Our article about the SRAM G8 hub now also covers the new G9 9-speed.
Additions to the article on internal-gear hubs — more about how to construct a multi-speed hybrid-gearing system using a stock 3-speed hub and two sprockets and/or two chainwheels. It indexes even without index shifters! Photo courtesy of Mark Stonich.
