You can get a service manual for your 1982 Chevy Capris, so why can't I get the same thing for a 2019 Trek full suspension bike, is their argument. And they're not entirely wrong, but miss the fact that bikes are modular assemblies and you need only be familiar with the standards for fitting parts, not the details of the specific parts. You can't fit the tail light assembly from a 2010 Honda Civic onto a 2019 VW Jetta, but you can put the derailleur from a 2010 Trek 820 onto a 2019 Pinarello Dogma.
