Several months ago, I posted an idea for a slip-on aero seatpost fairing. Several of you pointed out to me that such a thing already exists. Right now, someone is selling a Parkpre time trial bike on ebay with a great example of a plastic seatpost fairing that integrates with the frame. This is a nice frame and the fairing is pretty slick. Still, does anyone know of a product like this that is sold as an accessory?

Also on the web, Cyclelicious has a post about Spezialradmesse, a German bike show. Check out a few pictures here. Cool stuff if you are interested in recumbents and other different pedal powered designs.
