Good Bag

I've put it through the wringer

I like the bag. It does stay straight on the bike and hauls exactly what I wanted it to. The only problem I have experienced is the small end has created a worn spot on the top tube of my bike that's pretty significant. If you can tolerate that it's a great bag. I ride 100 miles a week.. Tony

Perfect size, doesn't wobble

I bought this because during the summertime I prefer a looser fitting tech t-shirt over a jersey, and needed to make up for the lack of pocket space. This bag is nice and sturdy, and doesn't wobble on the frame. I only have a single 1/4 inch spacer underneath my stem and had no issues with the front buckle. I haven't had any issues with my knees hitting the bag as I'm pedaling either, but there is some very slight rubbing if I'm climbing out of the seat. The bag is large enough to fit two inner tubes, phone, ID/credit card, a gel, a couple of fig newtons, and some beef jerky. If you put your extra tubes in a saddle pack though you could fit more snacks. The way the zipper is positioned you could also carry a portable charger and run a cord to your bike computer. It's awesome to have your stuff right there in front of you, instead of having to blindly fumble with jersey pockets or try and pull something out of your saddle bag on the go. I haven't had this long enough to comment on whether it's going to mar the frame long-term, but the lack of wobbling leads me to believe no. There's also a felt piece where the front bottom corner contacts the frame/headset that's intended to prevent any scratches or paint rubbing.
