I own the medium size and this was a gift for my son in a small size which he loves. Very durable and capacious.
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.
Perfect size for two tubes, two H2O cartages, cartridge filling devise and two tire irons.
Fits well
Fits nicely under seat.
With changing temps in Colorado, I can store a light jacket in addition to my tube and levers
The medium is tight for anything more than a tube and a few tools. It's virtually impossible to squeeze in a wallet and cellphone. But my biggest frustration is the placement of the zipper. With the bag snugged up tight under the seat (which I assume is how it's supposed to work) you have to squeeze your fingers between the bottom of the seat and the bag to open or close it.
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.
Holds what needs to be held and doesnt become undone from under the saddle.
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 use for under seat storage for tools, keys, wallet and whatnot. I like it a lot it does what it was designed to do.
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.
