I’ve been biking more for fitness and I’m looking to take a multi-day trip this year. While looking at route options, I found a well-researched site called Bay Area Bikepacking with ride reports and photos from routes I could reach without driving a car. To keep track of these, I added the site to San Francisco Bay Area bicycle routes, along with some more ambitious ones from Bikepacking.com.

I stumbled across a great gearing calculator on Observable by Tyson Anderson called the Bicycle Drivetrain Analyzer and added it to Web bicycle resources. It leans heavily on visualization to show any number of drivetrain gear combinations, overlap, and spacing, primed for comparison. Only Shimano groupsets are built-in options, but it also supports manually specifying any kind of cassette or chainring combination.

I’m adding a stream of entries to the site so it can hold ephemeral thoughts and for others to follow changes. These entries show up for RSS users when significant changes are made or I have something to share. I’ll try to keep them short and leave the long-winded content for notes.
