Florescent green/yellow thing near riders' BB?
 
I've noticed that all of the Tour riders have some device attached to the bottom of their bikes, near the bottom bracket. It's a florescent yellow/green cylindrical object of some sort. What is it?

Thanks,

Scott

I believe it is a gps type device that tracks where the riders are on the course.

if you're talking about a yellow plasticky thing on the chainstay (tends to be closer to hub than BB), then its a tracking device.

Cool, thanks.

That is a transponder which chief use is to determine finishing order across the line. With all of the helicopters, motorcycles and camera's, I don't think they need gps to find out where the riders are.:)
