Outpost Bike Frame Bag (Black,

I've only just installed this on my Specialized Crosstrail (XL frame), but the Large size is great, and fits the frame very well when opened all the way. The bag is of a higher quality than I expected, as are the zippers. Zippers seem weatherproofed/rubber-seamed. Nice long side access pocket on the left, large compartment opening on the right. Right side also has small stretchy outer stash pockets, might fit some small snacks. Inner compartment has a Velcro divider flap to loosely section/divide items top/bottom. I have a 3L water bladder, my bike lock, pump, and plenty of room for some other items like a battery pack, lights, etc. if needed. I primarily bought this to get the backpack (and water bladder) off my back, and it does the trick. See my photo showing the top-down view — no issues with the bag being too wide while riding, even with all that stuff crammed in there. The opening to allow cables or a drinking tube to exit the bag is nice, but it's angled in such a way (facing towards the rear) that the tube has to wind back and forth to exit. It works, but opening facing forward would work better I think. A very small complaint. I needed to buy an extension for my water bladder hose so it reached to a comfortable length to drink from while riding. Plenty of attachment loops on the bag, to use with reposition-able Velcro loops to attach to your frame as needed. Worked great for me. I had been unimpressed with any of the other reasonably-priced, non-custom frame bags available. I even looked into a custom frame bag. But for the price I paid for this, I am very happy with the bag and will definitely consider this Blackburn product line for future bag purchases if it holds up over time as I put it into actual use.

Bought this for my daughters Super 73 eBike. It fits perfectly. The zippers seem high quality and work great. The pockets are spacious and adjustable. The bike looks more complete with this bag as it fits inside the big open void of the Super 73 where it seems like an engine should be.

I love this bag. For the price its very sturdy and accomodating. The bungie flaps on the side work great for my wallet and phone when I dont have it mounted to my handlebar. I replaced the velcro and tension straps that came with it and now attach the bag to my frame using 3 bungie cords of correlating colors to lace the bag and hold it there a little more evenly. Theres a matching top tube bag and also a rolltop/dryroll saddlebag that blackburn sells that matches this as well. The expansion feature works well and theres a velcro middle section that functions as a shelf within the bag. Easily carries several tubes, a pump, a wallet sized first aid kit, my lock and chain, and a few other tools with room to spare. Also the zippers open from the front to the back in case you should need to run a wire from a portable battery in your framebag to your phone/headlight/etc on your handlebar.

I agonized over which frame bag to buy based on all the different brands and sizes available. I wanted a bag that would maximize my luggage carrying capacity in the open triangular space between my top tube and bottom of frame for long bike tours, so I purchased the Large Blackburn Outpost Frame Bag. When it arrived, I was initially disappointed because it seemed too small for my XL-size bike frame, and too large for my wife's small bike frame. When fully opened, the large bag extended all the way to the bottom of the seat tube on my wife's bike and interfered slightly with her chain sprocket. Rather than returning the bag, I put it on my XL-size frame (it was 5 inches above my chain sprocket when fully extended), packed it full, and took it on a long ride. Even though the bag was slightly smaller than I wanted, I was very impressed with its stability and sturdiness so I'm going to keep it for bike touring and every-day use. For the large bag, you need at least 19 inches of space from your seat tube extending along the bottom of your top tube towards the front of the bike. The front of the bag then drops straight down approximately 3 inches in its front so you need to make sure you have at least 3 inches of space between your top tube and the bar that comes up from the bottom towards the front of the bike where the front of your bag is going to be. The large bag when fully opened extends approximately 10.5 inches down along the seat tube, so make sure you have at least 10.5 inches of space along the seat tube between your top tube and the top of your chain. The width of the bag seemed perfect. It was very close but didn't rub my legs when pedaling when it was completely full. I didn't purchase the medium sized bag but the website says the medium is 2 inches shorter in length than the large, so you probably need at least 17 inches of space extending from your seat tube along the bottom of your top tube towards the front of the bike to fit the medium bag, with all the other dimensions being the same as for the large bag. The Blackburn bag may not fit as well as more expensive customized-made bags, but the Blackburn costs a lot less, is very sturdy, and designed well. I haven't tried it in the rain, but would expect it to keep light rain out......but would put my precious belongings in a plastic bag inside if I encountered heavy downpours.

This is my first frame bag and I am liking it. After years of carrying backpacks and slings, this frame bag has made me realize that these kinds of bags are better. The quality of this bag is great and while it isn't 100% waterproof, it will work for me. It holds a bunch of stuff, specially expanded and looks great while doing it. I have a 52 cm Kona Rove DL and it fits the bike well. It obstructs the water bottle holders that are on the frame but my Kona comes with bottle holders on the sides of the front frame, so not a huge loss. It fits my regular size u-lock, snacks, bike tools, safety kit with plenty of space left. I didn't want or need to spends hundreds of dollars on a frame bag, and so far this Blackburn is proving me right.

Just finished a tour of the Baja with this frame bag as part of my bike touring setup. Excellent quality, fit and usefulness. I was actually surprised at how good this piece was. It's just under 7 litres when expanded, and although not a huge amount of space, it took all of my t-shirts and soft items, freeing up space elsewhere. It became an integral part of the set up and I'll be using this for years to come on future rides. There have been some reviews stating it is not the actual size of 19.5". This is true as I measure 18.75". This is not a problem as far as form or function is concerned IMO.

Robust

Love the size and look. Well built and very convenient

Utilisé pendant 7 jours sur un trip en velo. Tres bonne qualité. Ne gene pas les jambes quand on pedale. Accès facile par fermeture éclair. Une grande poche principale (2 chambres a air, 1 trousse à pharmacie, 1 boîtier de lunettes y logent sans pb). 1 petite pochette laterale, pratique pour un couteau ou des papiers d'identité ou téléphone, et des petites pochettes extérieures ouvertes pour y mettre les barres céréales!!

サーリーのロングホールトラッカーで使用。 フレームがやや大きい(５８ｃｍ）ので、全ての取り付けベルトが届きませんが使用にはほぼ差し支えありません。 容量の小さな状態でも500ｃｃ缶が３本余裕で入ります。容量を大きくすると小さめのコッフェル、バーナー、多少の食材程度はすべて飲み込んでくれるので 自炊系プチサイクリングで活躍してくれています。 あまり重いものを入れると車体を振ったときに思った以上に左右に動くので-0.5。
