What is the yellow/black doodad hanging off Lance's fork?

[David Wuertele]

The doodad can be seen on the left side of Lance's fork in:

I don't think it is a sensor for a bike computer, because
there is no magnet on the spokes at that radius. He has does
have a magnet sensor, but it is far closer to the top of his
fork, and its magnet is obvious in the picture.

One theory is that it is a secondary bike computer that is
receiving data from a sensor somewhere else that wouldn't be
a reliable connection if he had it mounted on his bars.

Or maybe it is a secret laser that lance uses to burn out
his competitor's leg muscles. It has to be mounted low so
that it can aim up at the bottom of the competitor's thigh.

Its the transponder for the race organizers to track
the riders.

Holy ****! The detectors must be very close to the bike for
that to work. I guess if the detectors are out on the road
maybe you wouldn't need much power. Do they just put the
detectors at checkpoints or something?

The radio transponders they use at Sea Otter for all the
amateur events go on one's ankle. They have receivers
embedded in carpet-like pads at the start finish line.

Active transponders as small as that can have a range of
twenty meters or more depending on the setup.

Here I was all set to post a joke about it being his "pike pass" (car windshield-mounted transponder for paying tolls), when that's actually pretty close to the truth.

This kind of thing has been around for a few years in running road races, see for example www.championchip.com.
