Dear Karl,

"Here's a print of a photo of my Organic Engines Vapor with the ZZIPPER installed. The installation went quite easily. I had it installed within a half an hour of opening the box.

All in all this is an excellent product. I have not had enough riding to make any real claims, but it does seem to make the headwind and flat ground riding quicker."
