Rated 3 out of 5 by from Good quality bag, but with one critical flaw I bought this trunk bag together with a matching Topeak Explorer rear rack, thinking that it'd be a slick system. And it is, the bag seems well made and is of a good useful size. However, the flaw I unfortunately discovered is that when using this trunk bag gets in the way of my Ortlieb pannier clips, making it impossible to use both panniers and this trunk bag despite the matching rack. I am undecided if I am going to return it. By itself it still makes a nice day pack. If you don't want/need to use it with panniers then I would still recommend it.

Rated 5 out of 5 by from Great Storage Option Just picked this up and first used it to carry some drinks and take-out breakfast burritos. This is a great size to carry a lunch for two. Depending on how much I'm carrying I can use just the Rack Trunk or with a backpack to keep pack weight light and comfortable. This is the perfects sized cargo bag. As some YouTube reviewers have commented, the side zipper pockets can't hold much. But you can see in my pictures how its enough to hold a phone and I tossed a "mini" wallet that holds a driver's license and debit card when traveling. Nothing I'd keep in there while the bike is unattended but you can find some uses for those pockets. The best thing about this "trunk" is the MTX Quick Track, the ease of securing and removing the bag. I intend to get a second rack for my wife's bike so she can use the bag as well. The inside divider is a nice organizational touch. We used it to protect and organize a portable speaker. The addition of the water bottle holder vs. the previous gen. is really smart. The inside lid pocket is perfect size for a digital reader. The bag handle or shoulder strap also make it a great solution to a quick ride to the grocery store for an item or two. This rack and bag was more $ than I wanted to spend but the quality and usability is better than most others i researched.

Rated 5 out of 5 by from No More Sweaty Back Cool product. Saddlebag slides onto Topeak rack, holds tools, spare tires, lock & lunch. Handle so you can carry it with you. Not sure how weatherproof -- I rode in light rain not heavy downpour. On my (small) frame it touches back of seat, not uncomfortable. Water holder for extra water bottle. Great solution for day rides.

Rated 5 out of 5 by from Great bag, does what it says. Pros: - Ease of use over previous velcro strap-on bags - Secure, snaps in securely - Snap on, snap off. That's it. Easy. Cons: - It lacks the false top that its Velcro predecessor had, which unzipped to raise the top another few inches when needed. Why eliminate that? - The side pockets are next to worthless, as they only allow flat objects (letters, yada) - REI accepted my return with no question! And I purchased the next click up, which offers optional panniers on the sides. (Even then, I still miss the false top).

Are there any adapters or add-ons that allow this bag to be mounted on a rack that's not an MTX QuickTrack?

Asked by: DevNull
This bag needs to be mounted to a MTX QuickTrack; there are no adapters that make it work for a normal bike rack.
