Blackburn Outpost Cargo Cage

I spent a lot of time looking for the right water bottle cage for my front loader cargo bike (Riese & Muller Load4 75). I commute on it and don't drink while riding, but I wanted something that could hold a lot of different drink options from insulated coffee bottle, to water, to single use plastic bottles. The strong metal cage is perfect for durability. I really appreciated that it has numerous mounting holes spaced down the spine. I was able to use a hidden tracker holder behind the bottle cage to extend it from my mounting location on an inset cargo wall panel and then offset as high as possible over a protruding frame member. I don't love the straps, they are way too long and have to be carefully wrapped up when nothing is being carried. I plan to replace them with a Voile-style strap that's shorter in the near future. However, the straps do work and did a nice job of holding a fast-food plastic cup. I didn't even think about it while riding and several miles later, including an off-road shortcut, the cup hadn't spilled a drop.

This holds my 87 ounce insulated water bottle flawlessly. I love it. My giant water bottle is lowkey my adult security blanket, and it’s awkward to carry it in my backpack. So I’ve been trying to find a cage for it that would securely anchor an 87 ounce insulated water bottle to my bicycle frame as long as I’ve had it. I’m not gonna lie: This thing is overpriced at almost $40 for what is essentially just a piece of aluminum and some quality straps, but it absolutely WILL securely hold up to an 87 ounce water bottle when it’s full (thats about 11 extra pounds by the way) with no problems and honestly the straps would accommodate something even wider, but I’m not sure how much additional width you could fit between your knees before it would become problematic. And anything taller than my 87 ouncer wouldnt fit. But the cage is super adjustable, it fits my gigantic water bottle perfectly, it’d hold any size of Nalgene bottle or any other kind of water bottle effortlessly. Also, it’s literally a two hex key bolt installation that takes about 2 minutes, and the design is totally solid for extra large water bottles.

Low weight & cost and high functionality. I use this mainly for carry a dry bag on my touring bike, and sometime for carrying a large water container. The cage is sturdy and the straps work well. It appears the straps well have a long life. If not, they are easy to replace with Velcro or other straps.

Love the practicality for my exercise bike (Giant Defy 3 2015). It fits my JBL Charge 4 very well and keeps it in place perfectly. The weight is appropriate for the rack, but not mind blowing. That’s the trade off for it feeling very robust. My biggest gripe are the straps. There are no places to secure the straps when tightened down. I just make a few loose knots and they are out of the way. A better solution would have been a bit of velcro or elastic to secure the loose ends.

Returned: got it to hold an external e-bike battery extender and water bottles when not bringing the extender. Couldn’t fit into the space I needed. It’s too wide for many mounting points. If I could I would take off half a star because the included straps are bonkers.

I bought two of these Oupost cargo cages to use on my gravel rig and hardtail that I use for bikepacking. While they're not as light as some other cages out there, they're sturdier which for me means more than saving a little weight. The cages are metal. I have other cargo cages that are a composite material but wouldn't last with some of the rougher conditions I've used these in. Yes, there are only two sets of three mounting holes. You can still mount them to a fork though that has bosses. I like the fact that they can be adjusted by choosing any one of the different mounting holes to keep them clear of chainrings, etc.. They can carry large Nalgene bottles, Klean Kanteens, cargo bags and even a crowler can of your favorite local beer (see picture). I'm purchasing two more cages to mount permanently to the gravel rig so I don't have to swap back and forth anymore. Blackburn did a good job with these although they could do with a third set of mounting holes. I read a lot of people drill a third hole for fork mounting which could save people the time and effort.

I have this on my fat tire commuter ebike that I use to travel from the Bronx to Brooklyn in NYC. This thing is awesome!. It's rock solid and allows me to take my 32oz camelbak water carrier that won't fit standard size bottle cages. I use a 64 oz Wild Wolf Outfitters sleeve as pictured so I can also fit my sunglasses case and a few other items. Keeps everything off my back and makes for a much more comfortable ride with my water readily available when I need a drink. It's attached to my handlebars with the Lumentrail handlebar adapter which is another great product. Neither item has budged since installation which says a lot when you ride around in a city filled with potholes. Yes, the color is a weird, funky mushroom dirt color, but I'm not taking off any stars for that. If it really starts to bothers me, I'll just spray paint it black. Great product, don't hesitate to buy.

Update: the cinch does not stay snug. I’ve tried cinching it down tightly, it will slowly loosen up over the course of a ride. Just put this on my mtb, I wanted something to carry a larger 36oz stainless steel water bottle. Due to the geometry of my specific bike this is only one configuration I can use. Which is good I’m glad there are so many mounting holes. The fit is good, the bracket was nice and straight. The first time using it took a minute to cinch down the water bottle just right where it seems to be locked. But now that I have used it couple times it’s reasonably quick. Definitely not traditional bottle cage quick though. The downside I have is the metal water bottle will be bouncing on the base of the bracket. I will update after 10 miles of trail riding

ボトルケージ対応の小物、道具入れでは入り切らない容器入れを大きくしたくて買いました。ライトをバッテリー別にしているので大きい容器に出来て固定もしっかりしているので満足です。

Top secondo il mio modesto parere, belli anche quando scarichi, robusti li puoi caricare e caricare.

Good stuff 👍

2 años y aguantando. La mejor porta-botella (no la he usado para equipaje pequeño como la marca sugiere) y es excelente. mis botellas de acero de 24 oz, las de 32 oz, las de 34oz y la de 64 oz... todas, todas caben, se ajustan a la perfección y solo me falta tiempo para probar las de plástico de 5lt, a ver si cabe jajaja, la tengo instalada en mi Dahon plegable de 24'' y no estorba, no interfiere en el mecanismo de plegado, lo único es que si está muy justa en mis piernas cuando le pongo la botella de 64 oz (2 lts) pero no es culpa del porta botella, es más por es tamaño masivo de mi growler. Recomendado, estoy por comprar otra para mi bici urbana... lástima que no ofrecen descuento por cliente recurrente.

I own 7 of these - I can't stop buying them and fit them to most of my bikes. I use them to replace the bottle holders as I use a bladder on my back for water when Bikepacking. If your bike has fork mounts then these are a no briainer and I prefer them to other brands as they are robust, the straps are super tough and grippy, on the fork legs I can carry a cook kit and dry bags on the other - underneath the downtube I carry a bottle of fuel for the cooker - owning several means not having to swap them from bike to bike and everything is kept nice and streamlined. If you dont have the braze ons you can of course use zip ties to strap them on - I've used a slice of old inner tube behind then to both protect the fork leg and provide extra grippiness. For bike packing I'd say they were a gamechanger. 1 is none and 2 is one but 7 is still not enough !!
