It has a large capacity and i have ridden in several heavy storms and it is fully waterproof. I normally use it to hold my sleeping pad, compressed down sleeping bag, jacket, and 1-2 sets of clothing. It's only been on 3-4 rides so far and no rain sto...  Read More

The seatpost strap is all velcro, so it's easily adjusted to make this work. Then connected the main strap as normal. It's a plastic u of sorts - looking the side of the bag, the u sits sideways and reinforces both the top and bottom walls.

Easy to install. Doesn't look obvious to me, tho. I also like the way it looks. It’s kind of rugged looking.

After a single days use the material that comes into contact with the seat post was fraying and developing holes. It seems like the straps that you tighten work themselves loose over time with the jitter and shake of riding. I've definitely spent a fa...  Read More

The mounting system is great if you have toppeak rack! The slide system is nice but topeak needs to figure out what’s up with the rattling. It slides on the track nicely, but it will make a slight rattling noise at the rear of the bag where it meets t...  Read More

The dx version has two side zipper pockets. The panniers allow me to carry my laptop.

The bottle holder on the back turns out to be key for me! If you get one of these make a handle that uses the clasps on each end. One negative is i don't see a built in place to put a lock on it to keep the bag from being stolen or the contents stolen...  Read More

The bag is so versatile. Also really handy and easy to take on and off in two seconds. Aha its also very easy to clean.

Maybe it's prohibitively expensive? Is it a psychological consumer thing? This is like complaining a cat doesn't bark or fetch the paper, and a dog doesn't catch mice or purr. It's purely a marketing ploy to * buyers into having to replace stuff they ...  Read More

The pannier stripe does not show any reflectance or conspicuity. The side pockets are a joke they are just zippers on the side of the bag and are unusable. After the 6th day of use the zipper became fully separated and would no longer close.

You have to velcro the straps around the frame and this is where the frustration stated. No velcro loops or places to thread straps or bungees. Maybe with those two rear bottle holder straps or shoulder strap.

Must be time dilation. Be wary. You've been warned.
