What are those small yellow cylinders hanging off the right side of rear wheels?

Just a guess

Are they timing chips like they use in Marathons? I know for the NYC marathon, the runners tied a chip to their shoes that gave them their split times and their final time.

Amazingly, I have one of them...

But I thought it looked more cylindrical on video.

It's a transponder

I believe that is what it is called. Used for timing.
