My water bottle is a bit tight, going to get a slightly smaller one. Looks to be well made.

I'm a bit uncertain at this point. I was excited to receive this bag, it seemed like a good fit for my fat tire mountain bike.Immediately popped in my tiny multi-tool set, just a cheap one that came with the bike, it's a snug fit but it'll work. Or so I thought, until I installed the bag on my bike and found that I literally cannot get the tools out. They're stuck. In order to access I need to remove the bag from the bike, and remove everything else from the bag to bend the bag far enough to get in to slide the tools at all.Not sure if this is a dealbreaker or not, but it doesn't feel like the bag would be very happy if I made a habit of doing this. Ideally I won't make a habit of needing tools, but I carry them for a reason.It does have enough room for my mini electric pump, a light, and a few other goodies. I wouldn't store my phone there, but I like having it accessible if I pull over without getting off, so that's okay.As some other reviews noted, the "bottle pouch" is a perfectly fine pouch but it has no chance of holding a standard water bottle.Finally, the bag arrived dirty in the places I expect it to get dirty once mounted, so probably someone else had the same thought that I did, returned it, and here it is. Not a big deal, but I'd prefer to see it in the used-but-good-condition section. Not a big deal, if I keep it this is probably the cleanest it'll be anyway.

I bought this because I'd been training this year for a century road bike ride and need more space for gear to cover my bases while out many miles from home, but also to easily carry a third water bottle to stay sufficiently hydrated. It's a pretty good quality bag overall, with some nice elastic organizer spots, and fits my Smith spare lenses in their protective cases. Mounts easily to the rails and seat post.Despite being a fairly larger saddle bag, it doesn't protrude much and thus doesn't inhibit leg movement, or look unsightly. It also is pretty stable with minimal bounce while riding, even on gnarlier roads.About the biggest drawback it has it a water bottle doesn't go in or come out with ease when the pack is partially or totally full, so you can't take the bottle out while riding and have to stop. I'd also say that the zipper pulls merit improvement, because the metal wires in them don't extend far enough into the rubber tab portion, so they bend too easily when pulling them, especially if the bag is chock full and snug to close.All in all I'd buy it again, which sadly I will have to thanks to FedEx losing my bike and equipment on return shipment from the race I recently went to.

Stores a lot of stuff. Tools, tube repair kits, and multi-tool. When riding a fat bike, usually out in the woods. There may come a time when you need to fix a flat or tighten something up. This bag holds all of that. It's a big bag. My only gripe. The velcro straps could be longer were connected to the seat. To allow for a lower stance closer to the wheel. Reason. This bag is wide. Mount too close to the seat and it will rub on the inner part of your legs. Wearing out your shorts.

It’s useful actually, but quality is cheap and not as high as price ( the outside cover of the bag is not same as the picture, only the bottle cover is the same which is shining and looks good)

This is a nice bag for gravel bike riders, it has a carbon fibre look in the sun and it fits a couple of co2 cartridges with adapter. Plus spares tubes and all in one tool. You can slide your I’d and card on the opening. I’m able to unzip and get into the bag without taking out the water bottle. For those who plan on using the water bottle aspect, I wouldn’t count on it. It’s difficult to get a regular size bike bottle into it and out. I’ve added a bear spray adapted water bottle that can stay in permanently. I ride a lot of logging roads in the wild and this is a nice setup for those looking for this type of setup. Since I leave my water bottle in permanently, I was able to zip strap the rear clip on light to a visible position. Otherwise it hangs to low that I doubt a car will see it. Now it’s perfect! Rock bros makes good stuff for the money. I own a number of their cycling products.

Fits my plus size iPhone, a wallet, house keys, a multi tool, a spare tube, a patch kit, with a bit of room to spare. I like how stable it is. My seat post is long, so room is not an issue, but it might be for a road bike.

I have an e-bike and it is not a conventional frame so no bags could fit nor a water bottle holder could be install . This was the solution that meets my need . Seems durable made with quality material , could be a bit bigger to fit my wallet but that is ok .

Fully met expectation. The size was perfect for what I needed it for- MTB spare inner tube, tire levers, hex tools, CO2 cartridge, plier, chain plier, mini-pump. If this had a hook for key chain it would be beyond perfect.
