While devoted to building his site on technical bicycle information, Sheldon also documented his other interests and activities and his family history. Links to these pages are at https://www.sheldonbrown.com/SheldonMemory2019.html and most have been recently updated to display properly in modern browsers.
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.
The Elan 12-speed — biggest, baddest internal-gear hub of them all
All of our pages about fixed-gear and singlespeed bicycles have been updated. Information about derailerless drivetrains including workarounds for frames with vertical dropouts has been consolidated in a single article and expanded. Table of contents for these articles.
Pages about tandems and tandeming Sheldon Brown and family on home-built tandems[/caption] have been updated. We have more about disc brakes, brake levers, Gates synchronizing belts, and details about upgrading a cheap beach-resort tandem to ride with a child.
