When I began building bikes 10 years ago, Sheldon's site was already like an old book in the library.
It was a reference for older topics, such as recently when I needed to understand the internal workings of a Sturmey Archer hub to fix one.
However, it hasn't been of much help for the new developments from the past 15 years since his passing.
While less organized and sometimes messy, YouTube and many other sites can answer any bike mechanic question. Even ChatGPT generally provides good answers
yeah, same here. I do have one cheap French threaded BB bike and another 20+y old road bike with Shimano 600, so I'm a regular visitor of Sheldon's. But for anything 10y old and less, it's straight to Park Tool's Youtube channel to admire Calvin Jones' moustache wax. However, even Park Tool doesn't have the sheer volume of reference data and simple tables of measurements that Sheldon has gathered over the years.
The people who run the site now are adding new material to it. I built a new bike this year and actually found a lot of useful info for modern components on the site. Maybe our bike types don't overlap much, but I've personally found it useful still.
