About Topeak
Topeak has received an avalanche of awards and accolades since its founding in 1991. The company has developed such innovations as the JowBlow floor pumps with SmartHead technology, which sense and automatically adapt to Schrader and Presta valves without swapping out parts; the award-winning Morph series of mini pumps; the ALiEN multitools, which separate into different parts so cyclists can bring only the tools they need; and the Hexus mini tool and Bikamper personal shelter, which received the prestigious Red Dot award for outstanding design. The most important part of the Topeak story, however, is the passion of the founders and employees, who are cyclists, too. The company is dedicated to making the ride better, and focuses on creating products and accessories to help facilitate an escape from the traffic jams, cubicles, and mind-numbing meetings of everyday life.

The reviews for this item were very accurate. This is a well made product. My intended usage for the product was transporting work clothes to my office when I ride to work. So, will they fit?

The main compartment will barely fit two size 13 dress shoes. This is with a little shoving. Size 11-12 should fit perfectly. However, there was then no room for anything more than a single pair of pants. No room for the shirt. I was going to have to unzip one of the side panniers.

A single side pannier fits both size 13 shoes. They take up approximately 3/4 of the horizontal space in the pannier. There is still approximately 2-3 inches left vertically. The front-back depth fits them comfortably with no shoving, pushing, or any stress at all on the material or zipper.

Putting both shoes in side pannier, now leaves the main compartment free for comfortable packing of pants, shirt, belt, wallet, cell phone, etc. I still have the second side pannier completely free for "incidentals.

One final note: The side pannier will in fact fit a 17" MacBook Pro laptop in it. If you intend to do this, I would get a padded slip cover for it, as there is very little protection on the side. But, it is nice to know it fits!

Bear with me. I may still be on a honeymoon with my bike. I started commuting via bike this year and it's all still very exciting to me. I first bought a Topeak rack and just recently this bag. My previous experience with carrying a bag was primarily using bungee cords and backpacks. Lame, scary, inefficient.

What initially allured me to Topeak was the QuickTrack setup. No tying anything down or bungee cords or anything. You simply slide the bag in place and ride. What interested me in this specific bag was the side bags, which can fold into the bag. This is excellent for picking up a few groceries, transporting books, you name it. On a normal grocery run, I can carry the bag on me into the store (via included shoulder strap), with side bags put away. When I am ready to ride; bags come out, groceries in, click and go. Sooo easy.

When the side bags fold out, they Velcro to the hard flap which contains it when zipped. The bag also ties to the bottom of the rack. In the end, the bag is tied down and doesn't slide around at all.

My ONLY beef with the bag is that when I bike, my foot will occasionally brush the bag if it's full. This hasn't been a huge deal, but a slight annoyance.

Otherwise, everything else is great. Lots of space to store stuff, good quality, portable. Everything I could currently ask for!

This whole product line from Topeak is great. The rack is set up so that the bag can be removed and carried with you (shoulder strap provided!) quickly and easily, and snapped securely back into place. The ones with the fold up pannier bags make for a very versatile and compact cargo unit that can handle, one way or another, just about anything. I chose the model with the rigid sides because, apparently some of the earlier models with soft sides kind of scrunched when the pannier bags carried heavier loads. It seemed a reasonable upgrade and worth the price different. I haven't yet really tested the load limits, but so far it has been able to handle everything I have needed for around town shopping etc..But it seems as though it would be perfect for commuters as well, with room for extra clothing, shoes, lunch, laptop, and whatever. They deserve a design award for this baby. They have pretty much thought of everything.

This is an outstanding product but it has to be paired with the custom rack. Together they can't be beat. Slides on and off easily and is completely secure while on the bike.

I can't imagine one without rigid sides either.

The only gripe I have is that the zippers are very likely not going to hold up as long as the rest of the piece and I would have gladly paid more for them to be a better grade. (see review additon below)

I have owned TUMI bags my whole life for this very reason and the zippers on this bag are the only weak link.

I bicycle commute daily 15 miles round trip in Brooklyn, NY so between the elements and riding style necessary to stay alive out there it will need to be tough and I am confident that it will be. (except possibly the zippers...)

One final thing: I ALMOST bought the one with an expanding top but I was afraid that it would have been too big. That was a minor mistake on my part. The bags look much larger in the photos on Amazon than they really are. It is just the right size and I LOAD it up with clothes, computer, food, large Kryptonite lock, camera, dog (just kidding...).

Great product. Well done Topeak.

ADDITION 9/24/09: I have used this bag daily for 17 mile round trip rides in brutal New York City conditions and the zippers and the rest of it have held up beautifully. One of the zipper pulls came off but the zippers themselves have been no problem. I came back to this page as I now need to order the rain cover, something that should really be ordered as part and parcel in the beginning as you will want it if you spend any time at all riding in the rain. The bike's tires kick up all kinds of road dirt and other junk and the bag arrives at the end of the rainy ride filthy and soaked. An almost must-have for anyone who rides with this item in inclement weather.
