Modern bicycle computers are a far cry from the initial speedos many of us used way back when. From speed and distance to everything including GPS navigation, Bluetooth, Wi-Fi, and a host of performance metrics, modern head units are more like mini-computers than simple bicycle computers.

With all that computing power comes a vast range of data fields and metric options including current, live, and max speed, power, heart rate, and cadence, to name but a few. Most head units now offer custom workout pages giving riders options to chop and change the exact metrics on show.

With so much choice, though, the most difficult thing is often deciding just what to have on any given page. Many riders will opt for multiple pages with varying displays offering a host of live, average and max data.

Over the past week, we have collected a range of head unit displays to get a look at which data fields the world’s best riders in the Tour de France prefer to have in view mid-stage.

While all the obvious fields such as distance, power, and heart rate appeared throughout the bunch, a lot of riders now prefer to have the course map and navigation functions front and centre. The maps feature gives riders an idea of the course that lies ahead but, interestingly, of all the head units we saw, not a single rider opted to include an elevation feature on their screen.

Here’s what we saw.
