BlackburnOutpost Bike Frame Bag

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.

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.

I've been using this bag on my commuter for a couple months now, and I absolutely love it. The stock velcro attachment system was just okay, and I preferred to zip tie my bag to my frame, as you can see from my picture. Because this bag has so many attachment points it is held very securely within my frame this way.The construction of this bag feels durable, and after months of use it shows very little sign of wear.Having the option to expand and collapse the bag has also come in very handy, especially since it takes less than 30 seconds to make the switch.The design of the pockets is perfect for my uses: -One zipper on the right opens large central space. -Left side zipper opens thin but long pocket. -Two external right side stretchable pouches.The removable velcro interior "brace" keeps the bag from bulging out of the sides, and this works well to keep the bag away from my knees.Absolutely looking forward to getting my hands on more bags from this Blackburn line!

This is a solidly made frame bag, the zippers work great and have lasted a couple years so far. The expanding main compartment is very useful when you have a long trip and need to pack more stuff than usual. Fits my gravel bike frame perfectly and is easy to install. Have not had any issues with stuff getting wet inside either.

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 a great bag; a couple things they don't market well enough: the walls are made of a sturdy foam material so the bag keeps it's shape even with heavy items; and there is a small pocket on the non-drive side for things like keys, wallet, and phone. The only thing i'm disappointed about is the size is slightly off. The Large is supposed to be 19.25" long but is only 18.5", leaving about a 1" gap on my 54cm kona sutra. Despite that, i would still recommend this bag.

Me equivoqué de tamaño

Bottima borsa , con in più L estensione per bagaglio extra

This is a great frame bag, especially for the money, well made and fits plenty in. I would definitely recommend this bag especially if you are just dipping your toes into bikepacking. You definitely won't regret buying the blackburn frame bag.

I already have one smaller for my other bike, imI love this bag!
