This is the latest description of what I'm trying to do.
I've worked on this website for 5 years, and it is still evolving. The basic idea is a structure which explains how standard bikes fit together. By "structure" I mean a database where you can look stuff up. By "fit together" I mean documenting the main interfaces. What cassettes are available for my bike? What cranksets could be used on this bike? By "Standard" I mean bikes which adhere to the standard interfaces that have been around for decades, and for which parts are readily available. For example my "standard bike" is one with a steel frame, BSA bottom bracket, 135mm rear dropouts, quick release wheels, etc.

The intended audience is mechanically minded people seeking to maintain a fleet of standard bikes. People who are already working on their bikes, have done upgrades and repairs. The kind of people who watch the excellent bike repair videos on Youtube. Or research various questions with ChatGPT. These people typically own dozens of bike tools, and might have a little inventory of spare parts.

There are various organizations that encourage people to work on their own bikes such as "Our Community Bikes". They have dozens of bins of used parts, and have expertise in fitting them together.

What does this website have that is unique? I'm hoping to organize the main interfaces into a systematic database. As opposed to the knowledge being scattered in repair videos or ChatGPT. So you know exactly where to look up basic questions such as "what are the dimensions of a standard Shimano 8-9-10 freehub, and what cassettes are available?

What experience do I have? I have a bunch of bikes I have bought over the years and have maintained and upgraded. Anybody that makes heavy use of a bike is going to have encountered lots of need for maintenance and upgrades.

We use our bikes almost every day. Small utility trips, less than 10 km such as groceries, shopping On weekends we often do full day "destination" trips using Vancouver's extensive bike infrastructure. And then a few overnight touring trips a year. So our bikes have fenders, carriers and low gears. We leave the bikes locked for hours at various trailheads. They would have a relatively low resale value, so they are not targets for bike thiefs.

The bikes are steel frame with standard parts.
