Tire sizes too? For some reason we get funny sizes for tires and bike frames in Europe. I don’t really know what they’re based on, they do seen to have some kind of connection to imperial/cistomary but I never really know how it’s measured.
Good point. Forgot about tires. Tire sizes here are a mix of metric and imperial. My tires are 245 40R19, so 245mm wide, 40% sidewall ratio, on a 19" rim.
