Has anyone figured out what the progress bar on the status display means?
It seems to move around in ways unrelated to anything else I see happening.
It’s like experience points, you gain levels as you ride/play more on zwift and get access to new things, like right now i’m L7 and riding a “steel” frame bike with “classic” tubies.
how do you get back to the main screen to change your equipment? I believe each time I log in it just reads my power meter and other sensors and goes right to the choose your race.
One way to get to the settings is to pause the workout by stopping. You’ll get the screen showing your ride summary with the “I’m Done” button at the bottom. On the right side, about midway or a little below, are two buttons allowing you to access sensor selection/setup (labeled as “Sensors” I think) and your rider configuration (labeled as “Settings” I think). Click the “Settings” button and you should be able to select from whatever options you have based on your current level.
Hitting the “T” button will take you directly to the CUSTOMIZATIONS menu.
Allan is correct! It’s an experience-point bar that increases the more you play the game.
Greg and Noel both are correct in how you can access that menu during your ride 
Where is this progress bar displayed? I’m not seeing it (or I’m not looking in the right place).
