I was looking at the pic's that I took at the Giro and started to notice all the bikes were fitted with these things. Have a look at this pic and see if you know that these are. What I am referring to is the white plastic looking tab on the left side chain stay. All the bikes at the Giro that I have photos of are fitted with these things.

Ride On!

These devices are used for timing. Another person would most likely be able to describe them better than I would but they from what I know they are used at the finish line and most likely intermediate sprints to help determine the finishing order.

I'm not sure if they can give any mid-race feedback.

If you searched through the old forums there have been a number of threads about these as it came up last Giro.

No GPS, just an ID liek the ones used to go through toll booths. It tells the machine at the finish line who you are, the rest is up to a real computer.

Is it just me, or does the Saeco rider #159 look like a chubby junior rider?
Timing chips, I thinkbrider

Used extensively in triathlon, they are an identifier of the person, and will trip a timing mechanism at the finish (or possibly points in between). Triathletes usually wear these on their ankles on velcro straps (they're given at each race, but are considerably smaller). Due t the proximity of the receiver (triathlons use something akin to an airport security scanner), the units here may need to be larger to send out a stronger signal.

But this is basically guess work. I may be way off base.
Thanks for the confirmation on what I was assuming!! (nm)GeoCyclist
