Review on 🚴 The Ultimate Blackburn Outpost Top Tube Bike Bag: Secure and Spacious Storage for Your Cycling Adventures. by Robert Moloney

Case works great. The mounting holes on the frame matched almost perfectly. I had to tighten it a bit to get the sod screws in, but it helps keep the bag firmly in place. The iPhone 11 Pro Max fits on its side. The back corner of the phone sticks out a bit over the edge, but the lid has some depth so it still closes properly. The only minor downsides are the water resistant zips which can feel heavy and difficult to open while riding and out of one pocket the zip pullers had a small hole which allowed the zips to pop off. This is easily fixed by simply using pliers to close the gaps in the zippers. Overall it does exactly what it's supposed to.
