Adjustable Suspension: What are the yellow thingies?

Here's a photo of the Adjustable suspension upgrade:

What are the yellow things connected by a cable to the shocks? Do all v2.5 Roadster with the adjustable suspension have them already?

Also, the text in the description talks about setting "your preferences to Comfort or Sport." I thought the shocks just had a 1-10 adjustment. Is there something else?

Those are external reservoirs for the dampers. They are probably filled with nitrogen, which is compressed with the downward stroke of the piston. The valves in these kinds of dampers are outside the piston chamber, which allows them to be adjusted.

Thanks - has anyone adjusted them on their Roadster?
