TopeakAero Wedge Seat Bag - Strap(Return to Product Page)

I purchased a small bag intending to use it as a tool bag I could leave on the bike. I have a Toppeak Beamrack and found that with the rack as low as I could position it there is still not room for the bag. I kept the bag because I expect to find a use for it in the future and it looks as if it will be durable but I can't comment on how it actually performs. This is not a problem with the bag, just a compatibility issue with two add on accessories. The Beamrack has a raised bar at the front which the various baskets and bags attach to that caused the interference. A flat rack would probably allow the bag to fit, but I like the quick on, quick off mount so that is what stays for now.

The medium size (with zipper expansion if needed) fits nicely within my 145mm saddle dimensions, is secure and well-made. Swallows a bagged 25mm tube, tire tools, multi-tool, wallet and clamshell cellphone, couple tubes of Neosporin, couple individually wrapped sterile wipes, eye drops, cut-tire patch. I've used the zipper'd expansion only once, but it came in handy. (Riding home holding an acquired item in one hand is such a drag.) Would buy again. (Would have preferred dual zippers on the back, but all the other features still add up to best I've used.)

Nothing fancy. They work well, come in various sizes and work. I have 5 or 6 of them on various bikes.

I have a smaller version of this pack for my road bicycle. It has proven to be quite durable over several years' use. I got this larger version for my MTB. The fabric on the inside has already started to tear. The design of this "updated" version of the pack is actually less practical. On the older bags, the seat post strap was adjustable to grip the post tightly. This new version has the strap fixed to the bag, and allows only a very small amount of Velcro to connect. A very poor design change.

Overall this is a pretty good wedge pack. I bought this because the setback post on my Domane SL6 severely limits the underseat packs I can use and this was one of the few that works. The straps do a decent job stabilizing the pack under the rails, but there is some bounce with them. The biggest beef I have with the pack is its hard to unzip the waterproofed zipper because the pack isn't quite long enough to stick out beyond the rear lip of the seat, requiring some mildly annoying fiddling to get it open - definitely not a one-handed job by any stretch. The light loop is well-placed and wide enough to accommodate most taillights. The interior mesh pocket is perfect for a multitool.

Got this size small pack for my wife's new gravel bike. I like the way this style of pack provides a vertical mounting surface for tail lights. She is short so there is little space for a pack between the saddle and the tire. I use the medium pack on my bikes but am much taller, space below the saddle is not an issue. On my wife's bike there is only 1/2" between this pack and the tire so I recommend some changes to the pack design to make it more usable for the "little" people among us. As you can see in the picture of the pack, the zipper pull hangs an inch below which results in it rubbing the tire. Have to leave it partially open to avoid this. A dual pull zipper which closes at the top would eliminate this problem. The rear adjustment straps adjust from the bottom and the excess left over when tightened hang down and rub the tire. Move the adjustment part of the strap to the top to eliminate this. For safety, I bought a Garmin radar/light to alert her of cars approaching. There is no room on her seat post to mount the radar so it has to go on the pack. The tail light mount is on the bottom so the radar would rub the tire if mounted there. Had to move the tail light mount to the top rear of the pack where the Topeak logo was to make room for the radar/tail light. Topeak, are you listening?

I checked w/ BTD, because I wanted a bag that had a durable zipper (unlike the Fizik model I previously had) and one that would fit: 1 road tube, 2 CO2 canisters & valve, & a tire lever. BTD recommended this size.

First: It is HUUUGE! It fits all that with room to spare.

Second, it's too HUUUUGE. It's so big that despite being seated as far up against the bottom of my saddle as possible, it's so wide that it rubbed against my bibs, causing a hole. Not happy as they are Assos bibs.

It's so big, I doubt I would even use this on my MTB.

Third: The straps. In a word, they stink! They're too long. The strap that goes around the seat tube could wrap around it 2-3 times.

This bag is not appropriate for a road bike. It is only appropriate if you ride one of those beach cruiser type bikes with a massively wide saddle.

On the positive side, the zipper works well.

You've got all kinds of junk in the trunk- tubes, tire boots, tire levers, CO2 cartridges, CO2 inflator, house keys, ID... You need one of these, and you need one that isn't going to fall apart after one season. And here you are. Do it. These are tough, ripstop, and the buckles are sturdy. I put in 4-5K miles/year, and this bag shows no signs of real wear. Would purchase again.

Can fit a tube, C02, powerbar inside, a wind jacket when expanded.

Would have preferred the XL size, but this one still works with the dropper seat post all most all the way down.

Zippers feel a bit cheap and snag if there is any load, but otherwise well designed.

Even works with a Mtn bike fender on seatpost below, if seat is up high.

Overall happy, just wish zippers were beefier and size was a bit larger for an extra layer like a wind vest.

I have several different brands, and this is is among my favorites. Straps hold the bag firmly in place, and it has a small pocket on the opening flap. My only suggestion for improvement would be on the elastic loops underneath, I use these to hold a spare tire and the could be a little more generous in size. Better yet, have an adjustable nylon strep with a buckle for easy attachment and removal.

The medium version is perfect if (like me) you want to carry 2x-tubes, 3x CO2, inflator, tire levers and a mini-tool. Mounting is easy and stable (go w the strap & buckle option). Bag size will not bump your legs if properly mounted.

These kind of packs have been around for a long time and it's quite obvious that Topeak knows what will sell and at what price. Does it have what I needed in a pack? Well yea pretty much. Is the quality there? Really it's just acceptable. The zipper is good starting point. That's a cheap zipper folks. It also catches on the fabric. A nice YKK zipper is what you want but they of course cost a little more.

Another cheap feature is the velcro strap that connects to the seatpost. Those can really chew up shorts and after you cut the extra off so it doesn't catch you have to sew the end so it doesn't come loose at the end. I went ahead and ran a bead of silicone on the edges to ensure my shorts are protected from abrasion. Looks nice if you tape the middle to keep it neat.

While I had the silicone out I coated the elastic bands on the bottom for holding a pump. I had planned to use them and know they loose elasticity over time and the silicone will slow that process.

The ends of the saddle rail straps need a loop sewed on one for the other to thread through. Otherwise they flop around underneath. Not very aero Topeak. Just use a o-ring on yours.

One other feature that needed modification was the tailight holder. I commute at night and tailights need to aim straight back, not at the ground. So I made a little rubber wedge with ridges and glued it on. Keeps it nice and straight now. A little side note is that expanding the bag tends to have the same effect so if you use that you may be in luck.

The bag is a little difficult to open once attached as someone else noted otherwise I have no problem with the design. I wish they had a medium without the expanding bit as I find it plenty big already.

The reflective band is nice as is the saddle rail attachment except for the lack of a loop.

It was between this and and a Timbuk2 xt but there was no pump holder on that one. I ended mounting the pump elsewhere as my pump is the large sized Lezyne and looks a little lame sticking out. But BTD was sold out of the size and color I wanted anyway on the Timbuk2. Such is life. It's just a bike bag anyway. Someday maybe an aspiring bag maker will read a review such as this and will decide they are going to make a great bag. It's not that hard. I mostly fixed this one except for the zipper. I'll just have to keep my fingers crossed on that.

Oh and while you are creating the perfect bag make lots of cool colors and extra in medium sizes. Why is medium always sold out? Okay now I'm just getting greedy.

If you look at most bags you'll see that even after all these years most have some of these flaws so this is not to single out Topeak alone. I knew this bag would not be a great bag. You just try to figure out what will supply the most feat

Will using this Topeak Aero Wedge Pack for the Dirty Kanza and other Gravel Grinders. Pack has lots of storage for a seat pack.

Pack is very well made and very durable. Ability to expand makes it very versatile. Hold all the essentials tire stuff yet also has room for gels and more. My third pack from this manufacturer.

The thing I don't like is you have to unhook the bag from your seatpost to get anything in or out. Very inconvenient.

This is my second bag. First one had one of the straps wear out around the seat rail but lasted for years.

Its good for a couple tubes, levers, multitool, cartridges, and a few other odds and ends.

Fits nicely under seat.

I was looking for a large bag to replace an old performance wedge. This fits pretty much everything for me. Tube, 2Co2's, levers, keys, cell, patch kit, gloves, small wallet, eye glasses, and pretty good size first aid kit. I like the straps under the bag because it holds my pump (mini-morp).

It's big and ugly on the back of your road saddle, but it holds a lot of tubes, tools, and other stuff, so you'll probably never get stranded. After they're done mocking it, my friends all wish they had one. The loop strap on the back is also a convenient place to put your rear taillight when you're riding in the dark. I've got a couple of these bags now- they really work great.

I bought this product to be able to carry a spare tube, my tire irons, and a few bike tools. This bag easily accomodates all of these items with a tad to spare. I like the styling and rugged construction, and use the light strap on the back for one of my rear flashers. This is a good product.
