    Product: Topeak MTX TrunkBag DX With Expandable Top for MTX Racks
    Ownership: a month
    Tech Knowledge: average


    I've owned this bag for 1 month. Previously I owned the smaller cousin of this bag -- namely the EX version. I use(d) both bags daily, logging several thousand miles with them in the past 30 months. I much prefer this bag because of the expandable top and sturdier and roomier side pockets.

    After about 2 years the top compartment zipper on the EX bag failed, when I over-stuffed the bag. (The zippers on the DX are the same...I really wish they were beefier; they are adequate if the bag is not over-stuffed, however.). The side pockets on the EX version were an expandable mesh with zippers on top....these worked pretty well until the mesh developed holes that got larger and larger due to the things I was carrying, rubbing against the mesh over the years. The DX pockets have solid side panels, are roomier and just a better, more durable design.

    The interior volume of the main storage compartment of the DX is the same as the EX when not expanded.


    Just treat the top compartment zipper and zipper that allows the bag to expand with a little care. Don't overstuff the bag, which will put pressure on the zippers. Also, don't "race" the zippers back and forth when opening and closing the bag too quickly. These suggestions should greatly prolong the life of the bag.

    Other Thoughts

    To me, it's the best bag system out there, with the dedicated and required Topeak rack. (If you are planning on also carrying a side pannier bag or basket, purchase the more expensive, touring version of the rack with the extra, lower horizontal bar for holding the pannier -- or else the pannier or basket will interfere with the ability to slide the Topeak bag onto the rack's track rail.) As I said, I use the Topeak bag and rack every day, and multiple times per day. Not having to deal with Velcro straps or bungee cords is a wonderful thing!..carrying the DX bag while walking around town is very easy too, with the handle at the back of the bag. This handle is well built and will last. I should note that the DX bag is a bit heavier than the EX...but not a deal killer.

    Finally, I wanted to include why I did not buy the still larger bag above the DX with the built-in panniers.....1. The bag is heavier, making it less desirable to walk with...2. The panniers fold into the side pockets taking away storage room and co-mingling with the items being stored...3....The panniers will get dirty, wet and perhaps muddy. I didn't want to deal with cleaning them constantly before stowing them in the side pockets.

    For my "pannier" I use a Basil brand metal basket that I keep locked to the Topeak well!
