Garmin still leads Tour de France bike computer count

Garmin still sets the tone

Road.cc's look at Tour de France bike computers points to a familiar hierarchy: Garmin remains the dominant presence, with Wahoo still part of the leading group in the peloton. That matters because head units are no longer passive displays. For professional riders, they are central race tools, putting power, heart rate, speed, core body temperature and climb profiles in front of them while the race is unfolding.

The practical consequence is straightforward. When a rider can see effort, terrain and physiological feedback in real time, pacing and tactical decisions become more data-led. On climbs, in breakaways, or during sustained race pressure, that information helps turn a plan into something executable on the road.

New pressure from China

The more interesting market note is the emergence of two Chinese rivals. The source does not name them in the provided summary, but their presence is still significant because it suggests the top end of the peloton's bike computer space is becoming less settled, even while Garmin and Wahoo continue to dominate.

For data-driven cyclists, the takeaway is less about one device and more about the direction of travel: pro-level head units are increasingly judged by how much useful race information they can deliver, and how well riders can act on it.
