TopeakBicycle Saddle Bag, Hard Shell, Synthetic Fabric, Vehicle-Specific Mount, 1 Compartment, Buckle Closure

I really like this bag in size medium. It is very solid on the back of my bike and carries what I need it to carry without things bouncing around inside. A couple of things I think people need to know:- the medium bag barely fits an iPhone 13 pro in a slim case (not pro max, the small one). This is not because of the length of the bag, but because it tapers toward the seat post and gets too narrow to jam the phone in any farther.- as others have said, the Velcro strap that holds one end of the bag to the seat post doesn’t provide much contact between the hooks and loops. If you have a super wide, aero seat post it will probably be fine, but a normal sized seat post allows for about 0.5 inches of overlap between the hooks and loops. The easy solution: wrap it underneath and attach the end of the strap to the other side (I tried to show a picture of each way to attach it).- the screw-on seat attachment is very secure (you probably don’t even need the Velcro at the other end), but you will need a couple of cm or maybe 0.5-0.75 inches of seat rail to attach it. If your seat is adjusted fully forward you will need to consider the version of this bag with a Velcro attachment to the seat.- what fits in the medium bag? One inner tube will take up about half the space with the bag unexpanded. You could probably fit two with a couple tire levers and a co2 canister (depending on the size of your tires of course—mine are 700x42c). I have one inner tube, two tire levers, a couple of patch kits, and a folding hex wrench with room for my wallet and keys. I could fit a co2 canister or two and some other small items (a roll of electrical tape maybe? Or an energy bar?) if I expand the bag. The phone would be a challenge with an inner tube in the bag.-the little mesh pocket on the inside of the lid is more useful than I expected. That’s where I have my hex wrench, one of the patch kits, and the spacer for my disc brakes. It is really handy not to have to dig for that spacer every time I remove the front wheel.

Good size and keeps its shape. Attachment that goes on the seat really streamlines the look of the bag attached to the seat. Easy to put on and off. Quality zippers. Light attaches easily to the middle of the back of the seat. Worth the extra cost.

I previously had a Bontrager saddle bag with a quick release cleat that was starting to look pretty rough and needed to be replaced. That one was a bit difficult to find locally these days so I searched for alternatives. This came up in my search and so I took a chance on it. It feels high quality with a thick outer shell with nice secure mounting both the mount to the saddle rails and then bag to mount. Bag has plenty of room for my essentials, without even using the expansion. I have in it: spare tube, two co2 canisters, co2 head, Speedier tire lever and multi-tool. I also keep my wallet in my saddle bag on rides (with my phone in my jersey pocket). On some rides where I drive to the start I can also squeeze my keys in here. I like knowing I can expand it if necessary if I were doing a long tour and needed to carry any extras. I also love that due to the mount it doesn’t wobble side to side like Velcro-only mounted saddle bags. Those drove me nuts, and I’ll never own one again. We shall see how well this bag holds up, as I’ve only owned it a month or so now- but I gave high expectations. Highly recommend.

Easy to install. Good size for 3 co2 canisters, co2 pump and Allen wrench set. Has nice web pocket for ids. The only downside side is the slanted zipper opening has a loop for a flashing light. When inserting my light it points down toward the back tire instead of toward traffic coming up from behind.

The Topeak Aero Wedge Pack medium sized saddle bag offers plenty of space to hold a spare tube, CO2 pump, toolkit, and tire levers. There is a zipper that you can "open" to expand the inner compartment to hold a little extra. Previously, I had a Bontrager saddle bag, which was a tad smaller. Over time, the Bontrager bag became harder to re-attach and started to sag when a rear light was used.I also have a Topeak Aero Wedge Pack medium sized saddle bag on a hybrid bike. The older version uses straps all around, whereas the new version has the Fixer F25 mount. The new mount creates a cleaner look, does not flop, and easier to attach to the bike. The one drawback to the Topeak Aero Wedge Pack is that when empty, an iPhone 11 Pro Max is a very tight fit. Wish it was a tad longer/bigger to hold a phone properly.The Topeak Aero Wedge Pack also features 3M reflectivity, which is a nice touch. Overall, I believe that Topeak made a good quality saddle bag. Works great with either a road or hybrid bike.

A nice seat bag. Materials seem durable from the fabric to the stitching to the zippers to the attachment system. It's nice looking. There' s a reflective stripe sewn onto the lid / door / whatever you call the opening. There's also a loop you can use to clip on a rear light which is exactly what I did with it. On the inside of the lid, there's a small mesh pocket with elastic. It's big enough for a small wallet which is what I carry in there.What I was able to fit inside.........(with the expansion zipper opened up)1.) A spare inner tube.2.) My wallet.3.) A small bike multitool.4.) 3 tire levers.5.) My iPhone 11 Pro with a case on it.With that stuff the little bag is PACKED! The iPhone fits but doesn't exactly just slide in. Ya gotta sort of wiggle it in. The inner tube doesn't help as the rubber is like a brake creating friction. But it will all fit.However I decided to move my iPhone to a mount on my handlebars where I can see the readout on an app I use to track my route, speed, climbs, and calories. Having the phone out of the seat bag frees up room for a candy bar or two.As for the mount, it was easy to install and it keeps the bag stable and quiet at speed and over bumps as intended. It also allows you to remove or reinstall the bag in seconds. That's handy if you're parking your bike to zip into a store for a few minutes.All in all, this seat bag does exactly what I was looking for. Highly recommended.
