Perfect size for me as it has plenty of room for your gear and you can unzip it to expand its size a bit.
Big enough to keep all of my flat repair stuff for off-road, including a Lezyne pump with room to spare.
One downside is that the strap that goes around the seatpost doesn't have an attachment to keep the excess strap from flapping around - it does firmly attach to the seatpost, though. Ideally it would have some Velcro or something to keep the very end snug. I just tuck it in, but it's not an ideal solution.
This saddle bag is very nice and has a lot of room to put a few inner tubes, multi tool, and your CO2 inflator and cartridges. It has an expandable zipper around the middle if you need to add more stuff. I would have given the bag a 5 star rating, but I don't like the long straps that dangle on both sides. Perhaps they could have put a bit of Velcro on both straps so they won't dangle and flap in the wind.
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).
Medium fits tube, multitool, tire levers & spare CO2. Strap mount is secure. Strap on the back handy for the tail-light.
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.
Like this bag....fits under the seat nice and tight. Lots of room and I really like the loop on the back to clip my rear light on! Good price too! Great little bag!
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.
Very high quality, well designed - things fall into bag. Size seems small for medium. Able to get allen wrenchs, tire tool, ID, cell phone, tube and a patch. Tight fit for those items. Handy mesh holds a key or other small item. Didn't get the larger one because i heard they hit the thigh on pedal stroke.
I trust and like Topeak products but this is not one of them. I like the size and features of the bag. It fits everything I need for my gravel bike. I like the expandable zipper. However the strap for the seat post easily wears through the stitching that attaches it to the bag and you find that the bag now sways around uncontrollably making it not very functional and a waste of money. Look elsewhere.
Needed to replace my pack that had totally worn out over the last 10 years, couldn't find the exact match for it at Planet Bike, so I tried this Topeak pack, very pleased! It has a better profile to attach to the bike and the volume was just right without the expansion feature. A single zipper instead of a dual zip like the last one, but it seems smooth, we'll see if I get the same distance out this on as I did the last one.
Holds what needs to be held and doesnt become undone from under the saddle.
Use it on my rd bike. Spare tube, tire tool,valve remover, small bike tool. Just what I need
Perfect size for two tubes, two H2O cartages, cartridge filling devise and two tire irons.
Fits well
With changing temps in Colorado, I can store a light jacket in addition to my tube and levers
I bought this one to have as a backup of another of the same make, model, and size. The seams are separating on the other one and there is noticeable wear where the velcro seatpost strap makes contact with the bag material. Still, I'm buying another one because I like the size and overall design of this bag. And, I suppose, the devil you know is better than the devil you don't know.
I'd been looking for something this size for a long time. Perfect for all I want to carry!
This is a good size for a spare kit. Id get the large if you want to stick an second tubeadditional CO2 cartridges.
The Topeak Aero Wedge Pack-Strap is an excellent seat bag with room for 2 tubes, tire levers, CO2 cartridges, nitrile gloves and a multi-tool in a size medium bag without even having to use the expansion feature. The straps allow quick & easy transfer from one bike to another and make for a very secure attachment. The zipper opening is sturdy & reliable and it is easy to attach a clip-type tail light to the back of the bag. Over the years I have purchased 5 of these for the bikes in our family and they have proven to be both durable & reliable as well as being an attractive unit. They also have kept the contents dry when I have been caught in a rainstorm. Highly recommended!
