Looking at Trek Madone frames I see on the off-side chainstay that there is something called a "Duotrap" by Bontrager - can anyone tell me what this thing is and what it does?

Unfortunately like a lot of Trek stuff they do a very poor job of explaining its actual use. Is it a cadence sensor? Is it a speedo? One of the outside comments mentioned that it pairs with Strava. Well, I think that I used Strava at one time and didn't like that everyone in the world had access to your courses and speeds.
