Excellent bag for so many occasions!!
First off: Despite the photos, THIS IS NOT the MTX 2.0 bag. I thought it was, which is why I bought it. Although the descriptions don’t mention anything about it being the original style, I’m kind of glad that I got this one instead. From what I was reading & seeing in videos on YouTube, this version has 2 zippers on either sides of the pockets, whereas the MTX 2.0 only has the one, so you have to zip and unzip it the entire way. I know it’s kind of pedantic, but to me I actually like that small quality-of-life feature. Outside of that and the MTX type, they are practically identical, so I am not going to take off any stars.The bag itself is excellent quality!! Despite it not being waterproof, the main compartment seems like it has a waterproof lining to it. Do not take that as fact though because I haven’t tested that aspect of it. Also, the adjustable divider inside is super nice to have, and the pockets on top, the expandable top, and the bungie laces on top are absolutely amazing.The panniers seem to hold a very large amount, and I could even get my laptop and several books inside, so this will be perfect for bike-packing. They also fold up nice and clean into the side pockets, and there’s even room left over if you wanted to put some smaller things inside like a wallet, keys, small tools, handcuffs, mice, etc.It also even has a nice shoulder strap so you can carry the bag with you when you leave the bike. (May be a little more cumbersome with the panniers out)My main concern (I haven’t used it on any rides yet) is the lack of any kind of Velcro (or similar) fastener for it attach to the sides of the rack. It does, however, have a bungie cord at the bottom of the panniers with a looped end which you can use to fasten to the bottom of the rack where it attaches to the frame, but on my Salsa Journeyer it’s way too long and I can’t attach it to anything, so I’m going to have to find a solution for this.Gorgeous bag, very well made, and HIGHLY recommended!

Solid Quality with a reasonable price
This is my second Topeak bag. My first was nice enough that it ended up on my wife’s bike. It is not a huge amount of space on the top , but it works well. I stuff items in there that I might need and for riding the trails that is perfect. (I put in glasses a rain coat, a hat with plenty of room. The paniers I use only occasionally, but they are perfect for going to the store and picking up a few items – they won’t hold a weeks worth of groceries, but they do hold enough to eliminate car trips for me when I need to get there for a few items. I found the quality of the bag to be good. Nothing to complain about. There is a tag on the back of the bag and I use that to hang a light on. That works well. If they actually made a place to clip a light that would be great, but the tag works well enough for me. I have never had any bag loosen or fall off And the clip has always been easy to connect and detach. (I also have my rack slightly tilted towards the front as Topeka recommends). I use this bag on trails but am not an really rough and tumble biker. For me the bag is a good size and for almost all trips eliminates the need for a back pack or something else. The first bag I bought has worked well for a couple years now, so I expect the second to do the same. While they are pricey, I did check out other bags and I find the quality to be excellent and the price to be very competitive with comparable products.

Amazing fourth dimensional bag!
I exaggerate only slightly; it does seem that the Topeak MTX Trunk Bag DXP is larger on the inside than it is on the outside. I am using the DXP with the Topeak Explorer Bike Rack attached to my Specialized Sirrus hybrid bike.I’ve only had the DXP for 2 days, so I can’t speak to how it will stand up to long term wear and tear, although it does seem to be very well made. I am in love with this bag! My first outing was to the local farmer’s market. Parking near the market is very limited, so getting there by bike works prefectly. I locked up the bike and strolled through the market, picking up a long loaf of French bread, a huge bunch of Swiss chard, arugula and basil. I grabbed a bag of tomatoes and some fresh mozzarella. Returning to the bike, I wan’t sure that everything would fit, since I already had a couple of bottles of water, some tools and other items in the bag. Amazingly, everything fit. The bread and the bunch of swiss chard were too tall to close the zippers on the side bags, but everything rode safely and securely.A couple of hours later, I went out to the grocery store and bought a good sized cart full of items. I loaded the DXP: in one side bag went a 5 lb bag of flour sandwiched between 2 bottles of wine and topped with a bag of limes and a wedge of cheese. In the other side bag went a box of dishwashing detergent, a half gallon of milk a 1/4 of a watermellon and a bag of lemons. I filled the top compartment with a dozen eggs topped with a large bag of tortilla chips. All of the zippers closed! The side bags have an expandable pleat running through the center that allows them to grow to fit the contents. The weight distribution is terrific; with most of the weight lower than the top of the rear wheel, the effect on balance isn’t noticeable. When I reached home, I was happy that I could just unsnap the DXP from the rack and carry it into the kitchen. No bags required!The final outing of the day was an expedition to the municipal pool for a swim. I carried the towels, bathing suits, sun screen, goggles, shower stuff and a few other odds and ends for me and my girlfriend. Once we were there, I could take the DXP right into the locker room. Very nice!The DXP has a mesh pocket on the rear end for a water bottle, another mesh pocket on the top for small items, a small bungee net on top for things too long to fit in the top compartment and a small strap on the back that I use to clip my Planet Bike Blinky Super Flash Tail Light. Inside the cover of the top compartment is a small pocket that I use for a few tools.The side panels are well designed. Folded up, there is enough room for a Kryptonite Evolution Series 4 Standard Bicycle U-Lock with Bracket (4-Inch x 9-Inch) (if you seperate the U from the bar) or some small items. This U lock will also fit in the top compartment. Once you open them, the rigid side covers fold against the rack stays and prevent the nylon bags from hitting the spokes. For extra insurance, there is an adjustable bungee at the end of each side bag that can be snapped onto the bottom of the rack.This is a really great piece of gear!

Muy buena compra y a pesar de que su tamaño, tiene un espacio aceptable para guardar cosas

Muy buena calidad.

Lo primero es que hay que tener un porta equipajes de la misma marca, ya que éste lleva un rail por donde se desliza la bolsa.Perfecto para cuando no necesito mucha capacidad de carga y puedo dejar las alforjas en casa. En mi caso, puedo llevar esta bolsa más las dos alforjas sin problemas.

Perfect.

As an enthusiastic cyclist who often commutes and occasionally indulges in longer journeys, storage is a key concern. The Topeak MTX DXP Trunk Bag has not only met but surpassed my expectations. Here’s a rundown of my experience:Pros:Robust Design: Made with high-quality materials, the bag has withstood various weather conditions, from sunny days to unexpected rain showers, keeping my belongings safe and dry.Spacious Compartments: The bag is thoughtfully designed with multiple compartments, allowing me to organize my items efficiently. The expandable panniers are particularly useful for those days when I have a little extra to carry.Quick-Release System: Mounting and unmounting the bag from my bike is a breeze, thanks to the MTX QuickTrack system. It’s both secure when in use and easy to detach when needed.Reflective Features: Safety on the road is paramount, and the reflective strips on the bag ensure visibility during low-light conditions or nighttime rides.Sturdy Zippers: The zippers are smooth and durable, ensuring easy access to my items without any snagging issues.Cons:Weight: While the bag offers ample storage, when fully loaded, it does add a noticeable weight to the bike. However, given its storage capacity and durability, this is a minor trade-off.In summary, the Topeak MTX DXP Trunk Bag has been a game-changer for my cycling trips. It seamlessly combines functionality with safety features, ensuring that my rides are both convenient and secure. For cyclists in need of reliable storage solutions, I can’t recommend this bag enough!
