Perfect size! Great mounting system! Clever fold-out panniers!
OK,I have been using this bag daily on my work commute for about a month now, and I absolutely love it!I respect something that is well engineered and this bag certainly is that!That said, this bag is made to be used with Topeak MTX racks. If you don’t have one of these, either buy one, or look for a different bag.While I gave this bag 5 stars, it is not perfect, but certainly worthy of 5-stars.First the good points:-Perfect size for what I wanted. I love the fact that I can have a clean looking bag on the rack that has fairly large panniers ready to fold out when needed. The main bag is pretty good sized. The bag comes with a velcro divider, that can be placed anywhere, but I don’t use it as I prefer the single large space. That space will accommodate a carton of 12 eggs (actually 2 cartons). It will also hold a full sized iPad, although that has to go in at an angle, so it limits what else can be carried with it. It can also hold a medium size U-lock.-The easy click mounting on the rack is fabulous! Very easy to take on and off and very secure when mounted. The panniers include shock cords to loop around the bottom of your rack, so they are also very sturdy when utilized. The quick release is a very simple design, but works great. It also appears that if the spring ever broke, it would be replaceable by just removing one screw. I doubt that will be necessary, but I always like having repair options.- The panniers are well designed and hold enough for my needs. One pannier is able to accommodate a medium weight jacket or a pair of pants and shirt with ease. One pannier will also easily hold a pair of size twelve shoes. I have stuffed a fair amount of groceries in there, and it has held up fine so far, but I will revise this review in 6 months or so to see if any problems arise.OK, so what could be better?Well, I guess the zippers could be beefier. A few reviews knocked the bag for the zippers. Honestly, they seem pretty good to me. They are all double-zippers, which is nice.They open and close easily, but I suppose heavier duty ones would be better. Also, the handle on top does make the top zipper support all the weight of the bag when carrying that way. I guess this might stress the zipper over time, but if you use a bit of caution, I don’t think it will be an issue.One last thing I wanted to point out is that you can store a little bit off stuff in the side pockets even with the panniers folded up. I was storing my spare tube in there and it fit fine, but you certainly don’t have a lot of extra room as the panniers take up most of it.All in all, a very clever design that I think is worthy of 5 stars!I hope you found the review helpful and feel free to ask any questions. Cheers!

Never leave home without it!
These are great bags that work great with the Topeak rack. Just slide in and click. Easy peasy. I have one for each bike and they hold small first aid kit, lock, small tool assortment and depending on the day a shirt, possible rain jacket, workout clothes etc. Perfect size bag for bringing along the essentials plus

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.

Compré esta trunkbag en julio de 2019 y la busqué ahora por curiosidad de ver cuánto habÃa subido de precio, pero sentà que merece una reseña. En estos casi cuatro años de uso, ha probado ser súper resistente y duradera, está hecha con materiales de verdadera calidad y, salvo detalles de uso, se mantiene intacta. Las alforjas laterales te permiten meter de todo, tus tennis, una toalla grande, una caja de cereal (por si la quieres para hacer las compras). Se la recomiendo a todo ciclista urbano que quiera una solución para no trae mochila en la espalda, o a quien quiera hacer rodadas largas.

Muy buena compra y a pesar de que su tamaño, tiene un espacio aceptable para guardar cosas
Bruno Castillo M. –
Muy buena calidad.
Iñaki –
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.
