I have no added another hub from the Sutherland’s lost pages to to our Internet republication of Sutherland’s Handbook of Coaster Brakes and Internal-Gear Hubs — : the Shimano coaster-brake 7-speed. Here’s a page from the almost-finished draft – John Allen.
Sutherland’s planned to cover new internal-gear hubs in the 6th Edition (1996) of its Handbook, but then left them out. In straightening up my office recently, I found the nearly finished draft pages. We have permission, and we’ll be adding them to our Internet republication of Sutherland’s Handbook of Coaster Brakes and Internal-Gear Hubs — including trouble charts and comparative parts lists not to be found elsewhere. First hub is now online: the Shimano 4-speed – John Allen.
We have a much expanded description of how to rebuild a freewheel, now a new article and no longer just a paragraph in our main article on freewheels.
Every once in a while we go back and review our pages to deal with product changes and link rot. We just did that with all our pages about Sachs and SRAM internal-gear hubs. You will find product manuals here which are hard to find anywhere else. You can start with our main page about these hubs.
We have updated all of our pages about Sachs and SRAM internal-gear hubs, fixing broken links and, regretfully, indicating that SRAM is now no longer making internal-gear hubs. But many of you are using these hubs, and we are maintaining information on them. Main page with links to others.
As of 2018, fatbikes and disk brakes have led to several new axle-length standards. The problem of disk brakes’ pulling the hub out of the front dropouts has been addressed with thru axles, which insert into a fork with a hole rather than a slot at the end of each blade. Our chainline page and cribsheet as well as our frame spacing page and cribsheet are now updated to cover these developments.
Our gear calculator is now updated to cover the newest cassettes from Shimano, SRAM and SunRace. — Still to update: the French- and German-language versions.
Our Shimano 7-speed hub page is now updated to fix the links which broke when Shimano redid its Web site. We have also added information about new models, and made a few improvements in the text. All of our pages about Shimano internal-gear hubs are now up to date.
We have updated our article about Sturmey-Archer 4, 5 and 7-speed internal-gear hubs to reflect changes in hub availability and new documentation.
