27.2 mm Seat Post/Trunk Bag Recommendations

OK, so I love the Topeak system, but the seat post drives me insane. The 'universal' mount for extra-wide posts, coupled with a bolt on the side, rubs my legs... the wrong way. All the time. I don't have the extra lugs for a rack on all my bikes, and I want to be more flexible about which bike I'm on, anyway, so yes, it has to be seat-post-mounted.


Any recommendations on a non-universal low-profile (near the seat post) seat-post-mounted trunk bag?

How much cargo volume/weight do you need?

For day touring and perhaps lightly loaded commuting, I just picked up one of these from Ortlieb:

Did you get the Large? Can you give an idea of how much stuff can fit into it?
I really like the look of those for kind of a “big day out” bag, but am disappointed that they only make the waterproof one in the Medium size, and am wondering if I could get away with the M…

I got the large, but haven't tried it yet. It looks like you could fit a pair of shoes in it and perhaps a thin jacket, but not quite a 2 liter bottle. It also seems to have provisions for strapping a jacket or such to the outside. The mount, however, doesn't appear too robust. I'd consider a reasonable 5 pound limit there.

The Arkel Seat Bag also looks fairly nice. Bike Burrito is another option.

However, both of those may be smaller than you're looking for.

I have the medium Ortlieb seat bag. You might be able to fit 4 inner tube boxes (700x28) inside it.
