## Description

Product Description

Review: 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!
Review: 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!

### ⭐⭐⭐⭐⭐ Well designed, strong and useful bag
*by N***. on May 5, 2011*

When I bought my new bike recently I had one of the smaller ToPeak 6L MTX bags fitted along with an MTX track carrier. I love that bag and it's great for short to medium rides. However, I intend on going for longer rides and also potentially riding to work meetups where I will need to be able to carry more stuff and a change of clothes (I'm sure my colleagues don't want me sitting there in a pool of sweat!) :). I checked around and discovered ToPeak did a series of larger bags, and after reading so many positive reviews on Amazon I decided on this one. I am certainly not disappointed. This is a superb bag! It's 20L compared to my other, which is 6L, so overall there's a lot more room. The top of the bag has an extender zip which allows the top to expand upwards to allow for any larger more awkward items. The side packs can be used in their closed position for smaller items such as a portable hard drive, small notebook, phone etc, or they can be unzipped and fully opened out to work as panniers. Once opened up, the outer sides are fabric (albeit strong weave nylon), and would be great for clothing and lighter items, perhaps even a pair of shoes, but I certainly wouldn't risk putting anything too valuable in them, like a laptop, or heavy like books - I'm not sure they would really hold up to that kind of weight and wouldn't provide enough protection for a laptop or tablet due to the potential for knocking against the side bars of the carrier, not to mention the shock forces of hitting potholes and bumps in the road. When carrying my laptop I would always use a backpack anyway. I also like the little touches with this bag that set it apart, such as the carrying handle on top, and the extra water bottle holder on the back. As with all the MTX bags, this one is a breeze to fit to the MTX track on the carrier, and removes in seconds. Loads of room, very secure, no fear of it falling off during a ride. Excellent product overall.
