Product: Topeak Trunkbag DXP
Rating: * * * * * (5 out of 5 stars) : Outstanding!
I’ve used Topeak’s Trunkbag DXP bicycle bag now for six months and everytime I fill this bag to the gills with groceries or work clothes for commuting, I’m impressed.
Every time.
So impressed that I feel compelled to take a photograph of the latest bunch of things I’ve managed to fit in this bag.
Here is what makes Topeak’s DXP bicycle bag a winner. As you’re about to see, it’s not a short list of kudos!
- Topeak’s QuickTrack system rules! The bottom of this bag slides into a track on my Topeak Explorer bicycle rack and snaps securely to the rack. This bag isn’t going anywhere and it becomes ONE with the bicycle rack. No velcro straps (although it has those too for folks that don’t have the Explorer rack) and no stability issues with the bag in the event you decide to attack that hill on the way home and jump out of your saddle.
- The saddlebags or panniers fold up and zip close so that they’re out of the way when you don’t need them. That adds some nice versatility since there are times the cavernous center storage area provides plenty of carrying capacity.
- Reflective striping keeps you visible in low light. The bag has reflective striping all around it and has a nice long vertical stripe when the panniers are down and expanded.
- The cup holder on the end of the bag can store a few extra items or that huge 32 oz drink you just have to grab when you’re almost done with your commute and you’re parched!
- The cup holder on the rear of the bag provides an attachment point for a rear light.
- Just when you think you’ve run out of room, a zipper around the top of the bag opens the “two-stage” top that expands the height of the center section by at least two inches.
- The denier nylon construction continues to hold up well despite what the elements have thrown at it.
On a recent grocery store trip I carried the following items and had room to spare: 2 boxes of cereal, 2 boxes of heat packs, bag of bagels, 4 bananas, six-pack of Jello, bag of coffee, box of cream cheese and a couple of boxes of medicine.
Small grocery store runs are very possible with this bag and the 1,220 cubic inches of storage can be a blessing to bicycle commuters.
But enough talk! Check out these photos so you’ll see for yourself how the Topeak DXP Trunkbag expertly handles your storage needs and dramatically increases the utility of your bicycle.


That is a serious bag!
Wow! I have been thinking about different cargo options for my bike. This looks like a good one. I guess it wouldn’t work quite as well with a different rack, though.
Dottie / Trisha,
This bag is an incredible asset when you need to store a bunch of stuff in a platform that is very stable and full of versatility.
I agree, however, that if you don’t use this bag with the Topeak Explorer bicycle rack you lose some of that stability since the bag is not attaching with the center groove.
Justin,
Great blog. I also have a Trek Valencia… and have a few questions regarding the pannier.
Do you know what the difference is between the EXP and DXP? I guess one is an upgrade from the other…
Also what does the bag look like when it comes off the rack? Is it easy to move around? I really want to get the bag so I can do some proper shopping… but I want to take the bag into the supermarket & therefore wonder how easy it is the carry etc…
I look forward to your reply.
Thanks, Colin
cjay,
The DXP and EXP are similar in that they both have saddlebags that expand out of the side pockets. The DXP is larger – size is the real difference between the two.
When I grocery shop, I use one of those "green" bags instead of getting everything in plastic and then unload the groceries into the DXP bag in the parking lot while its attached to the bike.
When the saddlebags are down, the bag is unwieldy to carry on your shoulder.

Sorry for offtopic
Great site! I use this very same bag on my commutes. It's great, no doubt. Good luck with the commutes!
Thanks for the great review. I just bought the topeak explorer rack and am currently looking for a good bag for commuting to work. Have you used this for transporting a laptop? I see topeak also has a special laptop carrier and am trying to decide between the two.
