What about something from this page? I ordered the candy bar bag, which seems like it is NEVER going to get here. But one of the seat bags would be big enough, maybe the banana bag?

It just feels so good to get the Camelback off my back, I can't even imagine going back.

My basic setup is a small seat bag with a couple tubes, multi tool, quick stick tire tool on the back, and Bento Box for cell, Jelly Belly Sport Beans, and my camera or an energy bar on the top tube. I can only fit one bottle on my frame. Topeak Road Morph (tiny) frame pump. That stuff satys there and never changes or gets removed.

Then I have a Topeak Seatpost rack, quick release. I have a small bag and a big bag with zip out panniers with side supports that will hold up to 20# of stuff. I use that for very long rides, but the small bag is enough to holds plenty of stuff for any ride up to 100 miles. I am really happy with that system. I don't take the rack off, ever, and it has bungie straps that could hold a lot of clothing as you warm up. Or a rain jacket just in case. Or a ziplock with snacks.

But I wanted more stuff to be more accessable without stopping, because I felt like I wasn't eating enough on long rides because I didn't want to stop, but couldn't fit enough of a variety in my Bento box, and then someone here suggested a handlebar bag, which I am anxious to try out! And I think that might be good for Centuries, too, and I won't feel like I shouldn't be taking my camera, etc. because of space.
