Question: is this bag compatible with ANY rear rack of just the Topeak?
Document: This bags mounts on my separately bought Topeak bike rack. It has space for items like rain jacket and pants; tools and spare tube that I carry on 50-miles rides. One tip for the buyer is to seal the bag with spray on water proofing because is otherwise leaks in rain water. The bag and rack serve as a rear fender in the rain keeping the tire spray off the rider.
The MTX trunk bag met all my expectations. It has plenty of room for a spare inner tube, bike pump and tools. I am also able to carry along extra water and snacks for longer bike road trips. The trunk bag easily attaches to my rear bike rack and locks into place. Well made and worth the price I paid.
Just the right size for a rear carrier and Amazon had the best price too. Sliding the bag onto the rail was easy after the first try. Would recommend to anyone.
Clips on nicely to the compatible rack. Sturdy construction with  double zippers on the main compartments (hard to see in the pictures). Actually holds two gallons of milk (snugly, upright) if the top is left un-zipped (as they stick above the top by several inches).
This pack is sturdy and quick to put on or take off. My old pack Velcroed on and wobbled a lot, which meant i had to work to reinforce it and get it snug. Note: You need to purchase an MTX-compatible rack to use the slide-in, slide-out mount & clip that makes this pack worth the money.
I use trunk bag with the shoulder strap all the time and easily put it in my gym locker. I highly recommend this trunk bag used with the topeak rack of course.
I put it off. I bought a cheaper bag. In the end, I ended up buying this MTX Trunk Bag and it's well worth it. Very nice. Well constructed, fits perfect on the Topeak rack, a must have.
Bought this with the Topeak bike rack and it works really well, holds a lot of stuff, stays securely on the rack, and is easily detached. Only complaint was that it arrived without the strap but Amazon quickly replaced the bag and it's all good.
I love this bag but I didn't realize I had to buy a certain rack to go with it. It will only work with the Topeak Explorer Bike Rack, which is another $33. After I bought the rack and got over spending $80 for the two, I was very, very happy with this system. :)
Very Sturdy bag, but the zipper is terrible, it already broke on mine, I've had it less than 3 months. Also the bottom plastic plate that works with the topeak rack has cracked in half. Its strange because I have another similar bag from topeak that is doing just fine, and they carry the same stuff.
Answer: yes
