Anyone looking for a tail bag for the Stucchi rack might want to consider the 3516-0135 from Moose Racing. Its semi-rigid, fits the rack well, can be removed quickly with finger clips, and can be extended upward by opening a zipper.
Anyone with the Stucchi rack knows that cargo cannot be strapped all the way forward without chaffing the carapace behind the seat. To prevent this, I laced black paracord among the rack rails to standoff the tailbag. Even so located, it does not overhang the rack. Its rather small, but suits my purpose, so I'm happy with it.
My intent was to post a few photos of how it looks on the bike, but the 200KB max attachment allowance for this posting precludes even one picture. If anyone is curious about fit and appearance, send me a message I will email pics. rwake
