Why is the Topeak MTX DXP so popular?
The DXP is roomy and versatile.
The MTX DXP is the largest trunk bag from Topeak with a capacity of 1380 cubic inches (22.6 liters). It's more than just a spacious bag though - it's a great storage space. The side panniers fold-up when they aren't needed. The top expands for extra storage. There is a removeable divider in the interior to keep things separate when you need it and it has bungeed storage on top. It's even got a spot on the back for a water bottle.
The MTX system makes it easy-on and easy-off.
No more messing with velcro straps and wondering if you've strapped it down tight enough. This bag just slides right into an MTX rack with an affirming click to know it's secured. Push a button and it slides right back out. Off the bike you've got a carry handle on the top or for longer walks you can attach the included shoulder strap.
Remember to check out the Topeak MTX guide for help picking a rack.

Just What I Needed!
by Bill on October 14, 2020
Product:
Topeak MTX TrunkBag DXP With Expandable Top and Expandable Panniers for MTX Racks
Ownership: a few weeks
Tech Knowledge: somewhat high
Pros
Nice look, big panniers, durable construction. Love how the product fits seamlessly with the MTX rack. It is everything it advertised as. I like the reinforcement of the sides so the bag maintains it's shape. I am very satisfied with this trunk bag.
Cons
Only the Elastic Loop on the bottom of the fold down pannier. The loop needs to have a hook or needs a modification to allow the loop to fit the carrier.
A great interlocking bike rack and bag system

Product:
Topeak MTX TrunkBag DXP With Expandable Top and Expandable Panniers for MTX Racks
Ownership: a month
Tech Knowledge: low
Pros
I am a diabetic, so when I bike I must have food, drink, and a glucometer with me, especially on longer rides. I was hanging plastic bags off the bike (dangerous) or carrying a big backpack (annoying). When I found this online I knew it was the perfect solution. I was not disappointed. It installed quite easily and fits my Liz bike perfectly. There is no chance that it will slide off like velcro strap fasteners can, like I saw on other models. There are pockets for various other items you might need on a ride, water bottle spot, cell phone etc. The panniers have already come in handy when we unexpectedly came across a roadside produce stand on our ride. I love it.
Cons
It wasn't cheap, but you ultimately get what you pay for.
