Jerry Moos asks:
The Ti Duopar listed raises a question. I've acquired several Duopars on eBay lately, none titanium. The one on Hilary's photo looks very similar to mine. Exactly what parts of the Ti model are Ti? Can you tell the difference in a photo, or do you have to hold it and feel the weight difference?
---------------------
Using a magnet, the jockey wheel cage is Ti, as are the top and bottom plates that the primary parallelogram arms mount to are Ti (my work area is in the basement. A couple of cyclometer wheel magnets make their homes hanging from the sheet metal duct over my head, always handy for this application).
I have not weighed the two versions, largely because I can't find the steel "Eco" unit.
