Blackburn Outpost Bike Frame Bag

At first I was looking for a hard-shell frame bags, so that it doesn't look "soggy" when empty. I found a few, but they all turned out to be too small, I barely could fit my chain lock in there. I gave up and decided to try this bag. For me it ticks all the boxes - decent size, holds the shape very well (eventhough it's not a completely hard-shell) and I was also able to hook the portable Schwinn pump under it (which I couldn't do with hard-shell bags I've tried)!It also comes with a separator in the main compartment, which "velcroes" to the sidewalls at any location. I removed it almost immediately - I think it's an afterthought, as it prevents the bag to be fully opened - you have to always undo one of the sides, otherwise this separtor just pulls the walls together and you have very small opening. It does not seem to affect the sturdiness anyhow, so not a big deal.It is worth mentioning that this bag is exact copy of Roswheel Attack frame bag, except that Roswheel sells for $20 less. The reason why I decided to spend extra is purely because of style - I don't want blue expandable compartment on my black frame. If you don't care - consider Roswheel as a viable and cheaper alternative.

As I take day rides on trails, or ride to the post office or coffee shop I wanted adequate storage that I could keep an eye on while riding (I have heard stories of seat bags failing without the riders knowledge). I also wanted storage for my cable lock, tools, and whatever without losing storage for my water bottle. After a lot of searching and research I decided on the Small Blackburn Frame Bag for my medium frame Giant Roam Bicycle. It is perfect! Expands so the coiled cable lock fits in, has a divider, and small left side compartment. It uses the space on my bike well without consuming it. The bag has multiple attachment points for straps and it came with three additional straps that I did not yet use.It seems durable and well constructed and it is not prone to bulging, which is huge for me. I don't want my legs rubbing against anything. This bag is narrow enough to avoid any rub, yet really large and accommodating for a small size bag. It is available in a medium or large if your bike or needs are different than mine.I am always willing to pay for quality, and though not cheap, the Blackburn Frame Bag it is well worth the moderate price. Its the only thing I could find outside of a custom made bag that did exactly what I wanted. Highly recommended.

I like that this frame bag expands when the extra room is needed. Unfortunately for me, I had to order the small bag to keep it from interfering with the rear suspension shock and linkage that is inside of the "big triangle" on my frame. I really could use a bigger bag to hold my locks and air pump.

Great product but even in the small size I still couldn’t access my bottles. I have a 48 bike frame so it’s always a challenge. But if you decide to do a ride with a hydration pack and no bottles with this bag, that would be a win. You could also put the hydration bladder into the bag. I might try this bag again for a long race in the future. For now still looking for other options as I’m not sure how much stuff I want to add to my bike frame. And I don’t believe I could feel my legs touching the bag either when I put it on at home. Nice bag otherwise.

The small, when expanded, fits great as a wedge bag, filling the front part of the triangle. It's plenty big enough for a days ride while still letting me access my water bottle while pedaling. It's not a perfect fit, as there is a bit of a gap between the bottom bar and the bag, but it's not that bad for a non-custom bag. My frame is a medium, 54cm. I think the medium bag would be too long and not allow access to a bottle.Very durable and solidly built, especially since it costs half as much as other bags.My only complaint is the small pocket is short, only a little taller than a credit card. I was it was tall enough to store my phone so I don't have to put it in the main compartment.

Allows for enough space for a large bottle and to carry the bike using the over the shoulder technique for races. However the Velcro straps are barely long enough to feel confident on my xl frame.

Great bag, did what I needed it to do for my bike and looks really nice. I like the zippers, really sturdy and I also like the extension to correctly fit the frame of my specialize sirrus x 2.0 bike. I would recommend if your looking for a good bag on the market to hold your things while you focus on the road.

This replaced a different, smaller triangle bag that wasn't quite big enough. That bag also had very weak Velcro top tube straps that kept coming undone. Not so with this one. It fits everything I need, including my thick Samsung Galaxy Fold3. Velcro straps are nice and strong. The waterproof nature has been tested twice in heavy downpours (much to my displeasure). Everything inside was completely dry, on both sides.
