I sent a note off to the source asking about the metal unit (the link page is for the Delrin) and about what shipping would be for multiple units. Maybe my red suspenders are showing, but paying $40 to ship a $10 part just makes me squirm!

I also wonder why there is such a gap in the Givi bag selection between a 4-litre and the next step up (15 and higher). From the photos, I'd rather like a bag in the 8-10 litre range for the way I ride the Norge and the gear I like to carry up front. The 4 just seems to small, and the 15 is just a bit too much. Hey, where's Goldilocks when I need her?
