What is the device behind the saddle on all the riders' bikes in the 2015 tour? I'm seeing it on almost every bike. It looks standardized and electronic.

This is a special device that gathers the following data, according to this article:
the stage winner’s top speed, average speed and time per kilometer
the fastest riders up key climbs
the speed of the winner at the finish line
the top speed achieved by a rider on the day
average speed across all riders

Why isn't one of the big guys like Garmin already doing this, or rather, why didn't they beat Dimension Data to the punch?– ebrohmanJul 7, 2015 at 17:04

Most likely because they are already sponsoring a team and there's only so much money in the marketing budget. Plus having title sponsorship of a team will deliver far more impressions than an unbranded foxtail device bolted to the back of a saddle.– ChrisLJul 7, 2015 at 18:35

They are GPS trackers with a wireless data connection, GSM or EDGE would be enough for the data rate, but it might be something faster. The company supplying them is Dimension Data you can sign up for a free data report at the end of each stage here.

GSM (i.e. 2G, 64 channels per antenna) is no longer supported in some advanced parts of the world (Germany IIRC), the frequencies are reused for faster mobile communication technologies. Apr 9, 2019 at 8:40
