YMMV Review

This review is for the combination of the Topeak MTX TrunkBag DXP and Super Tourist DX Tubular Rack. I have separated some of the comments out individually but much of the review is about both and how they work together.

Design ★★★★☆

I was pleasantly surprised by this setup. There are several MTX bags to choose from depending on the size you are interested in. There are also several racks you can get that work with this system. I purchased the largest of the bags because I figured it was better to have more room if needed. For the rack I purchased the one that would work best for touring as well as commuting. When I tour I do not use this bag system so I needed a rack that would accommodate my other panniers.

Loaded for Touring

The MTX Bag has a rail on the bottom and a hook in the front so it can interface with the MTX racks. It just slides on from back to front and clips into the bar at the front of the rack. The bag has many features which help it adjust to your carrying needs. First off the inner compartment is all fleece lined and has an internal divider. This internal divider can be moved around inside the compartment or removed all together. It has Velcro attachments which allow it to be adjusted and it will stay in place when attached. The top of the main compartment has an expandable lid which allows it to accommodate larger loads. On the top of the lid there is also a carrying handle, mesh pocket and bungee cords for attaching loose articles on the go. In the back of the pack there is a small water bottle pocket and an attachment for a rear light. There are also side pockets on each side of the bag. They can hold a small amount of stuff when zipped up and can also zip open into side panniers to carry a much larger load. This allows this MTX bag to be as small as the smallest of the collection, but expandable to be the largest. The bag uses a durable 600 denier fabric for durability and it is treated with a Teflon coating to repel water and dirt.

Rack from Side Showing Attachment Points

The Super Tourist rack is built like a standard touring rack. There is a solid fender deck to block spray from below. This decking also features the MTX racking system to interface with the appropriate bags. The rack attaches to the bike via eyelets near the axel and adjustable bars that attach to the seat stays. Setup is a breeze as long as your bike has the braze-on attachment points. Otherwise you may have to get creative. The rack has two lower bars for attaching side panniers and bars down the side to keep the panniers away from the tire and secure them. It is made out of a hollow aluminum for strength and weight.

Performance ★★★★☆

I have been mainly using this system on my commute to work. It is 16.1 miles each way so I need to carry clothing to change into as well as my food. I originally used a backpack but it was starting to hurt my back and I liked the idea of not having a sweaty back when I got to work. The bag and rack interface really well and I have had no issues with them. The bag is easy to get on and off, slightly more difficult when the top pocket is extended but you get used to it. I generally do not need to use the side panniers due to the large volume that the main pocket can hold. When I do need the panniers they can be easily zipped out. While I have not ridden in too much rain I have had no issues when I have got caught in a downpour or snowstorm. Everything inside has stayed protected and dry. I have managed to spill some food on the inside and it has cleaned up fairly well, depending on the substance. I have really liked having the moveable separator inside the compartment; this allows me to keep my important stuff separate from my food. I guess if I really needed to I could use a side pocket as well. The water bottle pocket in the back is nice if you need to carry more liquid. I personally have not needed to so that is where I have stored my repair kit. There is a cinch cord at the top so I can securely put everything in there.

Top of Rack

The rack is more of an install it and forget about it piece. With the appropriate attachment points already on my bike, it was easy to install. It has been solid with the MTX bag and I have used it on my touring trip as well. The lower bars worked well with my side panniers and I bungee corded my tent and sleeping gear to the top of the rack during my trip. I even strapped a pizza up there for a short trip. I never had any issues with the rack. It has been solid and has all the parts you would expect it to have.

Overall ★★★★☆

While I have not had any issues with any of the pieces, the bag is a bit on the heavy side. My only other gripe would be the side pockets when the panniers are not extended. There is not much room in there but then you can just extend the panniers. I am really nitpicking here. The bag and rack have both been really durable and solid performers so far. Fortunately I have not crashed so I cannot attest to their durability to withstand a crash. As a commuting setup I would definitely recommend these. They even work well for light touring and in some cases fully loaded touring depending on how you set up your bike. The rack by itself works well in all cases. While I opted for the largest of the bags, your mileage may vary depending on your plans.

Long Term Check-In

    This rack is very light and strong. Looks great. It is advertised as fitting all size frames. Maybe it does, but I wouldn’t know because it doesn’t fit either of my bikes, because they don’t have threaded holes in the rear stays. I assumed (wrongly) that when they said it came with “all of the hardware to fit it” there would be clamps for my rear stays. Not so. I’m very disappointed. Since having this issue, I see that other reviewers on the web have found the same problem. It is likely to be common because there are a lot of bikes without threaded rear stays (more without than with?).
