For all those looking for the address for a Rogers Trike conversion kit, this is a web page I found that describes a triker's experiences and the Rogers address. I cannot guarantee that it is still up to date, but it wouldn't surprise me. Maybe I now know what to do with the frame that comes with my Campagnolo 50th anniversary gruppo! The frame is 2 cm too small for me for normal riding, but could work out perfectly for a trike! My experience tells me that you want a smaller seat tube and more cramped top tube on a trike to be able to do all of the acrobatics required to get the handling.
