It does pretty well holding stuff! When I went on a long ride recently I had a crystal Geyser water (I always feel better having that extra water - I guess I need to get another holder somewhere!), about 5 gu's and my camera, plus a few other odds and ends and it all fit fine. Its a topeak. I saw it on Caligurl's bike and really liked it because it wasn't very bulky. It also stands out from the bars a bit so I can still have my computer etc attached to my bars w/no interference. So far, I've been really pleased w/it.

btw, that basket for the back of the bike is really cute! If you get it, I'd love to see a picture on your bike!
