Trainer desks are ridiculously expensive for the relatively simple task their put up to. If you’ve got some scrap wood hanging around, as I always do, this might actually be a $0 project. Regardless, if you need to head out to the local hardware store this is the build process for a DIY $100 Dream Zwift Desk which can be built at home for your Zwift setup with just a few tools and not much material.
