The part is a TA Pro 5 Vis ( cyclo-touriste) chain ring set (54,40) with an outer chain guard and another alloy ring between the toothed chain rings. Pictures: http://www.flickr.com/photos/andyruland/5375088153/in/set-72157625748841959/ I have used TA cranks in the past but have never seen this configuration nor can I find any reference to it at several sites. Perhaps someone in the group can shed some light. Thanks Andy Ruland
